Applied to u-boot-tegra/next (along with some other pending Tegra patches for clocks/PLL/SPI/ums/etc.). I added T210/P2571 support to this patchset.

PTAL.  Also, there doesn't appear to be a 'gpu at 0,57000000' property in any t124/t210 DT file. Is that coming in another patch or one I missed?

Thanks,

Tom
