The powered rtc is accesseded via i2c so this requires IC2_TEGRA=y in order to work

Shouldn't the rtc module have a dependency on I2C and do a request_module on it? Building it into the kernel works, but only because the i2c-tegra module is doing a subsys_initcall instead of just plain module_init. Seems somewhat tenuous.

Looking at the i2c-tegra driver, I think it should be OK to built in as it seems to have the proper device tree matches in place. I'm curious if you tested this on any of the other boards that are built in the multiboard armv7 kernels though.

We should really be using KMS and modesetting here, is there a reason for this?
