[ARM] 3848/1: pxafb: Add option of fixing video modes and spitz QVGA mode support
Add the ability to have pxafb use only certain fixed video modes (selected on a per platform basis). This is useful on production hardware such as the Zaurus cxx00 models where the valid modes are known in advance and any other modes could result in hardware damage. Following this, add support for the cxx00 QVGA mode. Mode information is passed to the lcd_power call to allowing the panel drivers to configure the display hardware accordingly (corgi_lcd already contains the functionality for the cxx00 panel). This mirrors the setup already used by w100fb. Signed-off-by: Richard Purdie <rpurdie@rpsys.net> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
