2015-01-22drm/radeon: bind fan control on CI cards to hwmon interface (v2)Oleg Chernovskiy1-10/+43
This adds a possibility to control fan on CI parts via exported hwmon variables. Note that automatic ucode fan management pauses if you choose to enable manual fan control. Use with caution! v2: agd5f: fix formatting, squash in: minor fix for pwm1_enable exposed value Track smc control in addition to fan mode This fixes pwm1_enable being constantly set to 1 because of enabled smc control also handle the case where smc fan control is disabled.

2013-12-24drm/radeon/pm: move pm handling into the asic specific codeAlex Deucher1-0/+6
We need more control over the ordering of dpm init with respect to the rest of the asic. Specifically, the SMC has to be initialized before the rlc and cg/pg. The pm code currently initializes late in the driver, but we need it to happen much earlier so move pm handling into the asic specific callbacks. This makes dpm more reliable and makes clockgating work properly on CIK parts and should help on SI parts as well. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2013-12-24drm/radeon/dpm: switch on new late_enable callbackAlex Deucher1-21/+0
Right now it's called right after enable, but after reworking the dpm init order, it will get called later to accomodate loading the smc early, but enabling thermal interrupts and block powergating later after the ring tests are complete. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2013-12-24drm/radeon/dpm: add late_enable for CIAlex Deucher1-0/+29
Make sure interrupts are enabled before we enable thermal interrupts. Also, don't powergate uvd until after the ring tests. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
