drm/radeon: bind fan control on CI cards to hwmon interface (v2) 2015-01-22T15:38:48+00:00 Oleg Chernovskiy algonkvel@gmail.com 2014-12-07T21:10:46+00:00 36689e57502bd4de86abe5e55fff60b974416a52 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.

On boards with a high default fan speed this should reduce fan noise. Manual fan control is not enabled yet. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
