[PATCH v1 0/6] Add support for PMICs used on Tegra 3 devices

Greetings!

I have one more improvement for these drivers which is implementation
of do_poweroff ability directly into them. I have tested it already and it is
a trivial task. What is non trivial is that pmic can be not responsible for
poweroff if the device uses 2 or more pmics.

Solution I am looking into is use of 'system-power-controller' device tree
property to indicate PMIC used for poweroff function. Issue I have encountered
is how to properly convert dts prop into #ifdef to be able to hide or expose
do_poweroff at will, and if this is allowed at all in u-boot.

Best regards,
Svyatoslav R.
