X-Git-Tag: v2.6.35-rc1~451^2~38
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=49e02b7306cb7e01965fe5f41ba0f80085142f6e;p=pandora-kernel.git

drm/radeon/kms/pm: add additional asic callbacks

- pm_misc() - handles voltage, pcie lanes, and other non
clock related power mode settings.  Currently disabled.
Needs further debugging

- pm_prepare() - disables crtc mem requests right now.
All memory clients need to be disabled when changing
memory clocks.  This function can be expanded to include
disabling fb access as well.

- pm_finish() - enable active memory clients.
