Tomi,
Resending the patchset.
Checkpatch was not complaining at my end. Probably the mail server is
mangling the patches. I will send a tarball separately.
The only change in this version is that i've put the Video memory
initialization code in the board file.
The TSC2005 stuff is still thereas without it panel is not detected.
The merge conflict with TSC2005 patches if happens is very trivial to resolve.
regards,
-roger
These patches get the N900 LCD panel working.
Applys cleanly on 2.6.34-rc3
Changes since v2:
-Added Video mem init in board file
Changes since v1:
-Added Backlight control
Pre-requisites:

https://patchwork.kernel.org/patch/86319/
https://patchwork.kernel.org/patch/86320/

The SDI Display subsystem needs access to the vdds_sdi supply
regulator. This is TWL4030's VAUX1 supply on RX-51.

* [PATCHv3 3/5] OMAP: RX51: Add Touch Controller in SPI board info

To: Tomi.Valkeinen; +Cc: tony, linux-omap, linux-fbdev
From: Roger Quadros <roger.quadros@nokia.com>
The Touch controller and LCD Panel share the same SPI bus 1.
So, we need to define the touch controller in the SPI board info
else, the SPI bus will be contended due to invalid state of
Touch controller's Chip Select thus preventing the LCD panel
from working.
