This series adds support for the Tegra2x's display peripheral. This supports the LCD display on Seaboard and we use this to enable console output in U-Boot on the LCD.
I tested this on Seaboard, and found a couple of minor issues:
- Nothing sets up the environment to enable LCD output; I had to execute:
setenv stdout serial,lcd
... in order to see anything on the display. I'd expect patch 16/16 to cause this to happen automatically?
It's probably best to fix this by revising patch 16 rather than later, since I presume this is trivial to fix?
OK, skipping this as per your next message.
- The display works fine for cold boot, or hitting the physical reset
button, but when I execute "reset" at the U-Boot prompt, or "reboot" within Linux, the display is messed up; it looks like the LCD isn't able to sync to the timings sent by the display controller or something similar.
Since this is slightly a corner case, it may be OK to fix it later (but not much later; reboot is very useful to me.)
Yes I also noticed this, and I think we discussed it with the previous version also. Sorry I didn't add this to the commit message. It seems odd that a s/w reset would put it into a different state that a physical reset. I am not too sure how to approach this problem - I wonder if it might be one for Nvidia to look at?
I'll provide review comments on the patches themselves later.
