- Split old freq field into a tv_freq and a radio_freq. Prevents
that a radio tuner is initialized with a tv frequency or vice versa.
- When switching to radio mode initialize the tuner with the last

As a result of these changes the tuner module now remembers the
last set radio and TV frequencies, which is what you would expect
to happen.
- Move out of range frequencies to the closest valid frequency as per
v4l2 API spec.
- Fix incorrect initial radio frequency (multiplier is 16000, not 16)
- Add boundary check for out of range frequencies.
- Use new flag to check if the order of the CB and freq. depends on
the last set frequency. That is needed for some tuners or you can
get static as a result. The flag is added for those tuners where I know
that the datasheet indicates that this is necessary.
- For this new check use the last set div value, not the last frequency
as radio frequencies are always much higher due to the 16000 multiplier.

Seems that the CS5530A chip used in Geode GX1 systems has some crazy feature
that causes SMI traps when accessing the PCI configuration space of the video
device. Various GX1 BIOSes seem to use this 'feature' to hide the real BARs
of the device. This patch disables these traps (in an early PCI fixup) so
that Linux sees the real, physical BARs and not the virtual ones provided by
the BIOS.
This should allow the GX1 framebuffer driver to work on more systems that have
different BIOSes as the driver no longer guesses at what the virtual BARs
mean.
I'm not entirely sure it the correct solution as I can neither test regular
VGA console nor the X's 'cyrix' video driver so there might be some breakage
there -- probably best to get some more testers before applying it.

On a Dell Latitude CPi-A I noticed a strangeness wrt. the handling of an
external monitor by the neomagic framebuffer driver, namely when the laptop is
docked in a C/Dock II with the lid shut.
A cold boot would result in the BIOS configuring the video chip to use the
"external monitor only" mode, yet neofb would default to "internal LCD only".
An attempt for a quick fix by using the Fn-F8 keystroke to toggle the display
combination modes resulted in a reproductible hard lock, powering down being
the only solution.
The attached patch makes neofb probe the register for the current display
mode, using that value as a default if nothing was specified as kernel/module
parameter.

This fixes http://bugzilla.kernel.org/show_bug.cgi?id=5854
Root cause:
The dell_rbu driver creates entries in /sys/class/firmware/dell_rbu/ by
calling request_firmware_nowait (without hotplug ) this function inturn
starts a kernel thread which creates the entries in
/sys/class/firmware/dell_rbu/loading , data and the thread waits on the
user action to return control back to the callback fucntion of dell_rbu.
The thread calls wait_on_completion which puts it in a D state until the
user action happens. If there is no user action happening the load average
goes up as the thread D state is taken in to account. Also after
downloading the BIOS image the enrties go away momentarily but they are
recreated from the callback function in dell_rbu. This causes the thread
to get recreated causing the load average to permenently stay around 1.
Fix:
The dell_rbu also creates the entry
/sys/devices/platform/dell_rbu/image_type at driver load time. The image
type by default is mono if required the user can echo packet to image_type
to make the BIOS update mechanism using packets. Also by echoing init in
to image_type the /sys/class/firmware/dell_rbu entries can be created.
The driver code was changed to not create /sys/class/firmware/dell_rbu
entries during load time, and also to not create the above entries from the
callback function. The entries are only created by echoing init to
/sys/devices/platform/dell_rbu/image_type The user now needs to create the
entries to download the image monolithic or packet. This fixes the issue
since the kernel thread only is created when ever the user is ready to
download the BIOS image; this minimizes the life span of the kernel thread
and the load average goes back to normal.

This is a 2.6 patch that adds support for the watchdog timer built into the
EPX-C3 single board computer manufactured by Winsystems, Inc.
Driver details:
This is for x86 only. This watchdog is pretty basic and simple. It is
only configurable via jumpers on the SBC, and it only has either a 1.5s or
200s interval. The watchdog can either be auto-configured to start as soon
as the machine powers up (bad idea for the 1.5s interval!) or it can be
enabled and disabled by writing to io port 0x1ee. Petting the watchdog
involves writing any value to io port 0x1ef.
The only unfortunate thing about this watchdog (and it is not at all
uncommmon in watchdogs that linux supports) is that it is not a PCI or
ISA-PNP device and as such it isn't at all probeable. Either the watchdog
exists as 2 bytes at 0x1ee, or it doesn't. Thus, using this driver on a
machine that doesn't have that watchdog can potentially hang/crash the

Problem report (against 2.4.x driver) from Jeff Layton
<jlayton@redhat.com>:
An OEM noticed that the U6 qla2200 driver would hang for
around 2 minutes at boot time and then proceed normally. I
found that the delay was occurring when loading the new
firmware into the card, and was due to a
schedule_timeout(10) added to the bottom of the polling
loop.
Some testing showed that the load ram operation on the card
was very quick (on the order of a couple of jiffies), but
the sleep in the polling loop was making each operation take
around 25-30.
The attached patch corrects this by making it skip sleeping
during the load ram operation, since I believe we only do
that when the module is plugged in. It also skips sleeping
if the mbox_int flag got set during the current loop.
This corrected the hang on my test setup, and OEM also
confirmed that it corrected the problem for them.

This is the second version of the patch to address Christoph's comments.
Instead of doing the lib, I just kept everything in scsi_trnapsort_iscsi.c
like the FC and SPI class. This was becuase the driver model and sysfs
class is tied to the session and connection setup so separating did not
buy very much at this time.
The reason for this patch was becuase HW iscsi LLDs like qla4xxx cannot
use the iscsi class becuase the scsi_host was tied to the interface and
class code. This patch just seperates the session from scsi host so
that LLDs that allocate the host per some resource like pci device
can still use the class.
This is also fixes a couple refcount bugs that can be triggered
when users have a sysfs file open, close the session, then
read or write to the file.

When James Smart fixed the issue of the userspace scan atributes
crashing the system with the FC transport class he added a patch to
let the transport class check if the parent is valid for a given
transport class.
When adding support for the integrated raid of fusion sas devices
we ran into a problem with that, as it didn't allow adding virtual
raid volumes without the transport class knowing about it.
So this patch adds a user_scan attribute instead, that takes over from
scsi_scan_host_selected if the transport class sets it and thus lets
the transport class control the user-initiated scanning. As this
plugs the hole about user-initiated scanning the target_parent hook
goes away and we rely on callers of the scanning routines to do
something sensible.
For SAS this meant I had to switch from a spinlock to a mutex to
synchronize the topology linked lists, in FC they were completely
unsynchronized which seems wrong.

This adds a bitbanging spi master, hooking up to board/adapter-specific glue
code which knows how to set and read the signals (gpios etc).
This code kicks in after the glue code creates a platform_device with the
right platform_data. That data includes I/O loops, which will usually
come from expanding an inline function (provided in the header). One goal
is that the I/O loops should be easily optimized down to a few GPIO register
accesses, in common cases, for speed and minimized overhead.
This understands all the currently defined protocol tweaking options in the
SPI framework, and might eventually serve as as reference implementation.
- different word sizes (1..32 bits)
- differing clock rates
- SPI modes differing by CPOL (affecting chip select and I/O loops)
- SPI modes differing by CPHA (affecting I/O loops)
- delays (usecs) after transfers
- temporarily deselecting chips in mid-transfer
A lot of hardware could work with this framework, though common types of
controller can't reach peak performance without switching to a driver
structure that supports pipelining of transfers (e.g. DMA queues) and maybe

* There's now a "struct spi_driver". This increase the footprint
of the core a bit, since it now includes code to do what the driver
core was previously handling directly. Documentation and comments
were updated to match.
* spi_alloc_master() now does class_device_initialize(), so it can
at least be refcounted before spi_register_master(). To match,
spi_register_master() switched over to class_device_add().
* States explicitly that after transfer errors, spi_devices will be
deselected. We want fault recovery procedures to work the same
for all controller drivers.
* Minor tweaks: controller_data no longer points to readonly data;
prevent some potential cast-from-null bugs with container_of calls;

This is a driver for the ADS7846 touchscreen sensor, derived from
the corgi_ts and omap_ts drivers. Key differences from those two:
- Uses the new SPI framework (minimalist version)
- <linux/spi/ads7846.h> abstracts board-specific touchscreen info
- Sysfs attributes for the temperature and voltage sensors
- Uses fewer ARM-specific IRQ primitives
The temperature and voltage sensors show up in sysfs like this:
$ pwd
/sys/devices/platform/omap-uwire/spi2.0
$ ls
bus@ input:event0@ power/ temp1 vbatt
driver@ modalias temp0 vaux
$ cat modalias
ads7846
$ cat temp0
991
$ cat temp1
1177
$
So far only basic testing has been done. There's a fair amount of hardware
that uses this sensor, and which also runs Linux, which should eventually
be able to use this driver.
One portability note may be of special interest. It turns out that not all
SPI controllers are happy issuing requests that do things like "write 8 bit
command, read 12 bit response". Most of them seem happy to handle various
word sizes, so the issue isn't "12 bit response" but rather "different rx
and tx write sizes", despite that being a common MicroWire convention. So
this version of the driver no longer reads 12 bit native-endian words; it
reads 16-bit big-endian responses, then byteswaps them and shifts the
results to discard the noise.

This is the core of a small SPI framework, implementing the model of a
queue of messages which complete asynchronously (with thin synchronous
wrappers on top).
- It's still less than 2KB of ".text" (ARM). If there's got to be a
mid-layer for something so simple, that's the right size budget. :)
- The guts use board-specific SPI device tables to build the driver
model tree. (Hardware probing is rarely an option.)
- This version of Kconfig includes no drivers. At this writing there
are two known master controller drivers (PXA/SSP, OMAP MicroWire)
and three protocol drivers (CS8415a, ADS7846, DataFlash) with LKML
mentions of other drivers in development.
- No userspace API. There are several implementations to compare.
Implement them like any other driver, and bind them with sysfs.
The changes from last version posted to LKML (on 11-Nov-2005) are minor,
and include:
- One bugfix (removes a FIXME), with the visible effect of making device
names be "spiB.C" where B is the bus number and C is the chipselect.
- The "caller provides DMA mappings" mechanism now has kerneldoc, for
DMA drivers that want to be fancy.
- Hey, the framework init can be subsys_init. Even though board init
logic fires earlier, at arch_init ... since the framework init is
for driver support, and the board init support uses static init.
- Various additional spec/doc clarifications based on discussions
with other folk. It adds a brief "thank you" at the end, for folk
who've helped nudge this framework into existence.
As I've said before, I think that "protocol tweaking" is the main support
that this driver framework will need to evolve.
From: Mark Underwood <basicmark@yahoo.com>
Update the SPI framework to remove a potential priority inversion case by
reverting to kmalloc if the pre-allocated DMA-safe buffer isn't available.

This patch changes device_shutdown() to use the newly introduced safe
reverse list traversal. We experienced loops on system reboot if we had
removed and re-inserted our device from the device list.
We noticed this problem on PPC405. Our PCI IDE device comes and goes a lot.
Our hypothesis was that there was a loop caused by the driver->shutdown
freeing memory. It is possible that we do something wrong as well, but
being unable to reboot is kind of nasty.

Add bus_type probe, remove and shutdown methods to replace the
corresponding methods in struct device_driver. This matches
the way we handle the suspend/resume methods.
Since the bus methods override the device_driver methods, warn
if a device driver is registered whose methods will not be
called.
The long-term idea is to remove the device_driver methods entirely.

- Tunertype struct redefined to allow one or more tuner_params structs
per tuner definition, one for each video standard.
- Each tuner_params struct has an element containing an arbitrary
amount of tuner_ranges.
(this is needed for dvb tuners - to be handled later)
- A tuner_range may be referenced by multiple tuner_params structs.
There are many duplicates in here. Reusing tuner_range structs,
rather than defining new ones for each tuner, will cut down on
memory usage, and is preferred when possible.
- tunertype struct contains an element, has_tda988x.
We must set this for all tunertypes that contain a tda988x
chip, and then we can remove this setting from the various
card structs.
- Improves tuners array memory usage efficiency.
- Right now, all tuners are using the first tuner_params[] array element
for analog mode. In the future, we will be merging similar tuner
definitions together, such that each tuner definition will have a
tuner_params struct for each available video standard. At that point,
the tuner_params[] array element will be chosen based on the video
standard in use.

At least some versions of the via-velocity hardware only support
checksumming IPv4 frames in hardware. However, the driver is currently
setting the NETIF_F_HW_CSUM flag, which indicates support for more than
just IPv4. This results in errors when trying to use IPv6 over
via-velocity hardware.

I believe I see the race Michael refers to (tlb_choose_channel
may set head, which tlb_init_slave clears), although I was not able to
reproduce it. I have updated his patch for the current netdev-2.6.git
tree and added a version update. His original comment follows:
Our systems have been crashing during testing of PCI HotPlug
support in the various networking components. We've faulted in
the bonding driver due to a bug in bond_alb.c:tlb_clear_slave()
In that routine, the last modification to the TLB hash table is
made without protection of the lock, allowing a race that can lead
tlb_choose_channel() to select an invalid table element.

This patch allows the Atmel driver to work correctly with wpa_supplicant
and other programs that require some conformance with WEXT-18. It
should not affect current behavior of the driver. The patch does four
things:
1) Implements SIOCSIWENCODEEXT, SIOCGIWENCODEEXT, SIOCSIWAUTH, and
SIOCGIWAUTH calls for unencrypted and WEP operation
2) Accepts zero-filled addresses for SIOCSIWAP, which are legal and
should turn off any previous forced WAP address
3) Sends association and de-association events to userspace at most of
the appropriate times
4) Fixes erroneous order of CIPHER_SUITE_WEP_* arguments in one location
which are actually unused anyway
