Subject: drm/radeon/dpm: add pre/post_set_power_state callbacks (6xx-eg)
X-Git-Tag: v3.11-rc1~65^2~60^2~64
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=98243917d7cd64be923aad76c563de7e23b0b386;p=karo-tx-linux.git

drm/radeon/dpm: add pre/post_set_power_state callbacks (6xx-eg)

For r6xx-evergreen, they are no-ops as they don't support
any dynamic state adjustment.
