Changes made as suggested by Eric Miao (including fix to map_io
silly mistake!).
Originally designed by Intel, now sold by Crossbow (www.xbow.com).
Very little actually on board. The patch includes sensors and
similar as found on commonly occurring daughter boards.
Some of the drivers are not in mainline as yet as they are either
part of the IIO subsystem or need a lot of work before submission.
What is the position wrt to putting them in i2c board configs etc?
Support for these boards has been maintained outside the kernel
for a long time, but now that there is a good da9030 pmic driver
available the last major hurdle no longer exists.
All comments welcomed.
The Imote2's big brother (stargate2) will follow once any problems
with this one have been cleaned up and a few bits and bobs have
been added to the da903x driver. Hopefully the cc2420 driver will
get cleaned up and submitted in the not too distant future as
well.

Some smart panel requires a delay between command sequences, while PXA
LCD controller didn't provide such one, let's emulate this by software.
A software delay marker can be inserted into the command sequence, once
pxafb_smart_queue() detects this, it flushes the previous commands and
delay for a specified number of milliseconds.

For smart panels (LCD panel with internal framebuffer), the following
LCCR3 register bits have different meanings than the parallel one:
LCCR3_PCP - controls the L_PCLK_WR polarity
LCCR3_HSP - controls the L_LCLK_A0 polarity
LCCR3_VSP - controls the L_FCLK_RD polarity
To keep minimum change to the original parallel timing, the .lcd_conn
flags and 'pxafb_mode_info.sync' are re-used to reflect this:
LCD_PCLK_EDGE_{RISE,FALL} - configures LCCR3_PCP
sync & FB_SYNC_{HOR,VERT}_HIGH_ACT - configures LCCR3_{HSP,VSP}

The S3C64XX timer is running at the wrong rate due to the
assumptions made in the timer initialisation about the way
the pwm dividers work. This means that time on the S3C64XX
runs twice as fast as it should.
Fix the problem by moving to using the clk framework to setup
the pwm timer clock muxes, as the pwm-clock code has all the
necessary knowledge of how the timer clock inputs are routed.

The S3C64XX series has a new TCFG divider setting to allow the clock

TCFG divider settings and provide any other per-arch data that the
