[RFC PATCH 0/4] ufs: set power domain performance state when scaling gears

[Krzysztof Kozlowski]

Hi,

This is a proof-of-concept/RFC for changing the performance state
of power rails when scaling gears.

So far I added it as a parallel method to scaling clocks, thus
freq-table-hz stays in DTS, however OPP table should be probably
replace freq-table-hz entirely.

Best regards,
Krzysztof
