Dear Mike Dunn,
This patch adds a config option CONFIG_SYS_LCD_PXA_NO_L_BIAS, which causes the lcd controller initialization code to leave as an ordinary gpio the line that is typically configured as the lcd L_BIAS alternate function (this is the gpio 77 line).
For some reason (I don't have a datasheet), the lcd device on the palmtreo680 board does not use the L_BIAS line. PalmOS does not configure the gpio 77 line for the L_BIAS alternate function, and if it is configured as such, the lcd does not work.

The other option would be to pull the GPIO setup from the driver. That'd be the best.
Best regards, Marek Vasut
