This series moves these two drivers over to use driver model for video.
This involves the following steps: - Sync up some device tree files with Linux - Implement a proper PWM driver - Clean up and unify the driver code - Modify the existing drivers to work with driver model
The tegra20 display driver uses device tree bindings invented in 2011 before Linux had this or anyone was able to agree a standard. It seems possible to move it to the new bindings (like tegra124) except for the issue of time delays between stages. It isn't clear how this should work, and Linux implements this by including all LCD definitions in the kernel source code, and not using any delays. This causes strange display artifacts on the display when starting up, but perhaps is harmless to the display. Future work will sync up the device tree more for seaboard, and thus tidy this up for nvidia boards.
A bug in the keyboard driver is also fixed by this series. The series is tested on seaboard and nyan-big, the two boards I have which support a display.
This series is available at u-boot-dm/tegra-working.
