* drm/radeon/dpm: fix incompatible casting on big endianAlex Deucher2013-10-231-2/+2
| | | | | | | | | We use u16 for voltage values throughout the driver so switch the table values to a u16 as well. Fixes an incompatible cast error in ci_patch_clock_voltage_limits_with_vddc_leakage() picked up by coverity. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

* drm/radeon: use sw CTS/N values for audio on DCE4+Alex Deucher2013-10-231-0/+1
| | | | | | | | | | | Use the driver calculated CTS and N values rather than having hardware generate them. This allows us to use the modeline pixel clock rather than the actual pll clock when setting up the dto for audio. Fixes problems with audio playback rate on certain asics if the pll clock does not match the pixel clock exactly. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

* drm/radeon: rework audio optionAlex Deucher2013-10-183-31/+58
| | | | | | | | | | | | | | | | | | | | | | In 3.12 I changed audio to be enabled by default, but you still had to turn it on via xrandr. This was confusing to users so change it to minic the previous behavior: - audio option is set to -1 (auto) by default which is the current 3.12 behavior (audio is enabled but requires xrandr to turn it on). - if audio = 1, the audio is enabled without needing to mess with xrandr (previous behavior) - audio = 0 disables audio It retains the new feature of allowing the user to enable audio on the fly with xrandr, but turns audio on automatically if radeon.audio=1 is set which is what most users expect.
