NAK for this patch.
You are using drivers/soc/* as a dump yard for your SOC code which
is not the intention we created drivers/soc/.
Its really for subsystem drivers which doesn't have appropriate
home in Linux kernel today. From your above patch ...

This should go into drivers/idle/*. if you have dependencies, please sort
them out.

subsystem: drivers/power/reset/
For tegra/*pm*/, you can use drivers/power or drivers/base/power/
For SMP boot, ARMv8 expecting to have either PSCI based implementation or
device tree based boot scheme. you can move towards that model if possible.
Please find appropriate subsystem to move your SOC code and if you don't
find an appropriate subsystem, we can discuss adding that under drivers/soc.
The drivers/soc/* isn't a dumping ground so please don't abuse it.

Santosh
