[PATCH V9 2/3] powernv: Add support to set power-shifting-ratio

This patch adds support to set power-shifting-ratio which hints the firmware how to distribute/throttle power between different entities in a system (e.g CPU v/s GPU). This ratio is used by OCC for power capping algorithm. Signed-off-by: Shilpasri G Bhat --- Documentation/ABI/testing/sysfs-firmw
