The usbtouchscreen module implements a driver for the TSC-10 DM USB
touchscreen controllers, but assumes a 2-byte response for the
CMD_RESET and CMD_RATE commands, when they can be only a single byte
when no EEPROM is connected.
The driver worked with an earlier controller revision, but new
revisions of the controller fail.
It seems the problem is that the early controller had the
SEL4/EEPROM-CS pin high, but the new controller has it down, making
the response different.
Without the fix, the controller would answer the single byte 0x06
(ACK), making the init fail with -ENODEV because buf[1] is 0xFF (as
initialized before).
As the single byte is the only thing we need to check it was ok, there
is no need to verify the second byte.
The [0x15 0x01] case is the NAK [0x15] response for when there is no
data in the EEPROM [bit-0 of second byte set], so I let that be, as I
don't have any controller with an EEPROM.
With this patch, both the earlier and latest controller work the same.
Note: This was previously submited as BUG #11961 [1] on the bugzilla
tracker, but rebased to version 2.6.27.4 and with unnecessary comments
and printk's removed.

The appletouch driver has grown up from supporting only a couple of
touchpads into supporting many touchpads, which can have different
number of sensors, different aspect ratios etc.
This patch cleans up the current driver code and makes it easy to
support the features of each different touchpad.
As a side effect, this patch also modifies the 'Y' multiplication factor
of the 'geyser3' and 'geyser4' touchpads (found on Core Duo and Core2
Duo MacBook and MacBook Pro laptops) in order to make the touchpad
output match the aspect ratio of the touchpad (Y factor changed from 43
to 64).

Review comments were incorporated to improve the driver.
1. Some data was eliminated that was not needed.
2. Renaming of variables for clarity.
3. Removed unneeded type casting.
4. Changed to use dev_err rather than other I/O.
5. Merged together some functions.
6. Added kerneldoc format to functions.

When booting Linux on a txx9 board with VxWorks boot loader, it crashes in
prom_getenv(), as VxWorks doesn't pass firmware parameters in a0-a3 (in my
case, the actual leftover values in these registers were 0x80002000,
0x80001fe0, 0x2000, and 0x20).
Make the parsing of argc, argv, and envp a bit more robust by checking if
argc is a number below CKSEG0, and argv/envp point to CKSEG0.

- Setting the TFS pin selector for SPORT 0 based on whether the selected
port id F or G. If the port is F then no conflict should exist for the
TFS. When Port G is selected and EMAC then there is a conflict between
the PHY interrupt line and TFS. Current settings prevent the conflict
by ignoring the TFS pin when Port G is selected. This allows both
