Anyway, this is a collection of lots of small fixes that slipped from the previous pull request. All fixes are about ASoC, and the majority of changes are corrections of the wrong access types in ALSA ctl enum items. They are mostly harmless on 32bit architectures, but actually buggy on 64bit. So we addressed all these now in a shot. The rest are various small ASoC driver fixes. Among them, only two changes have been done to ASoC core, and both of them are trivial.

Equivalent change to the radeon driver. Note that with radeon this caught a bug in the dri3 DDX implementation, which asked for vblank interrupts when the pipe is off.

2016-03-08drm/radeon: Switch to drm_vblank_on/offDaniel Vetter
These should be functionally equivalent to the older per/post modeset functions, except that they block out drm_vblank_get right away. There's only the clock adjusting code (outside of pageflips) in readone which uses drm_vblank_get. But that code doesn't synchronize against concurrent modesets and instead handles any such races by waiting for the right vblank to arrive with a short timetout. The longer-term plan here is to switch all kms drivers to drm_vblank_on/off so that common code like pending event cleanup can be done there, while drm_vblank_pre/post_modeset will be purely drm internal for the old UMS ioctl. Note that with this patch Michel uncovered a bug in the dri3 implementation of the DDX (it does vblank waits when the pipe is off), which had to be fixed first.

2016-03-08drm: introduce pipe color correction propertiesLionel Landwerlin
Patch based on a previous series by Shashank Sharma. This introduces optional properties to enable color correction at the pipe level. It relies on 3 transformations applied to every pixels displayed. First a lookup into a degamma table, then a multiplication of the rgb components by a 3x3 matrix and finally another lookup into a gamma table. The following properties can be added to a pipe : - DEGAMMA_LUT : blob containing degamma LUT - DEGAMMA_LUT_SIZE : number of elements in DEGAMMA_LUT - CTM : transformation matrix applied after the degamma LUT - GAMMA_LUT : blob containing gamma LUT - GAMMA_LUT_SIZE : number of elements in GAMMA_LUT DEGAMMA_LUT_SIZE and GAMMA_LUT_SIZE are read only properties, set by the driver to tell userspace applications what sizes should be the lookup tables in DEGAMMA_LUT and GAMMA_LUT. A helper is also provided so legacy gamma correction is redirected through these new properties. v2: Register LUT size properties as range v3: Fix round in drm_color_lut_get_value() helper More docs on how degamma/gamma properties are used v4: Update contributors v5: Rename CTM_MATRIX property to CTM (Doh!) Add legacy gamma_set atomic helper Describe CTM/LUT acronyms in the kernel doc v6: Fix missing blob unref in drm_atomic_helper_crtc_reset Signed-off-by: Shashank Sharma <shashank.sharma@intel.com> Signed-off-by: Kumar, Kiran S <kiran.s.kumar@intel.com> Signed-off-by: Kausal Malladi <kausalmalladi@gmail.com> Signed-off-by: Lionel Landwerlin <lionel.g.landwerlin@intel.com> Reviewed-by: Matt Roper <matthew.d.roper@intel.com> Acked-by: Rob Bradford <robert.bradford@intel.com> [danvet: CrOS maintainers are also happy with the userspacde side: https://codereview.chromium.org/1182063002/ ] Reviewed-by: Daniel Stone <daniels@collabora.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: http://patchwork.freedesktop.org/patch/msgid/1456506302-640-4-git-send-email-lionel.g.landwerlin@intel.com
