Is it possible to get the tegra core patches applied? These seem to work
enough to get a system running and once the PM fixes are in there should
be no problems running big-endian tegra?
I don't think it's enough. Upstream kernel doesn't accept half working
solutions. It's not only PM that needs fixing, but i2c, timer, reset
handler and possibly more. You are enabling big-endian across all tegra
generations, but tegra2 won't boot at all for example. Patches must be
tested on all hw before applying. And nit: big-endian should be enabled
after all dependencies resolved.
Ok, we hadn't found any issue with the reset. I thought we had the
timer fix in this series. Most of the other drivers didn't use
any __raw code so we're reasonably confident they will work.
I didn't see any issues with the i2c from visual inspection, what's
wrong with it in big endian?
I've sent patch.
