On GLK the plane CSC controls moved into the COLOR_CTL register. Update the code to progam the YCbCr->RGB CSC mode correctly when faced with an YCbCr framebuffer. The spec is rather confusing as it calls the mode "YUV601 to RGB709".

2018-03-02drm/i915: Correctly handle limited range YCbCr data on VLV/CHVVille Syrjälä2-18/+73
Turns out the VLV/CHV fixed function sprite CSC expects full range data as input. We've been feeding it limited range data to it all along. To expand the data out to full range we'll use the color correction registers (brightness, contrast, and saturation). On CHV pipe B we were actually doing the right thing already because we progammed the custom CSC matrix to do expect limited range input. Now that well pre-expand the data out with the color correction unit, we need to change the CSC matrix to operate with full range input instead. This should make the sprite output of the other pipes match the sprite output of pipe B reasonably well. Looking at the resulting pipe CRCs, there can be a slight difference in the output, but as I don't know the formula used by the fixed function CSC of the other pipes, I don't think it's worth the effort to try to match the output exactly. It might not even be possible due to difference in internal precision etc. One slight caveat here is that the color correction registers are single bufferred, so we should really be updating them during vblank, but we still don't have a mechanism for that, so just toss in another FIXME. v2: Rebase v3: s/bri/brightness/ s/con/contrast/ (Shashank) v4: Clarify the constants and math (Shashank) Cc: Harry Wentland <harry.wentland@amd.com> Cc: Daniel Vetter <daniel@ffwll.ch> Cc: Daniel Stone <daniel@fooishbar.org> Cc: Russell King - ARM Linux <linux@armlinux.org.uk> Cc: Ilia Mirkin <imirkin@alum.mit.edu> Cc: Hans Verkuil <hverkuil@xs4all.nl> Cc: Shashank Sharma <shashank.sharma@intel.com> Cc: Uma Shankar <uma.shankar@intel.com> Cc: Jyri Sarha <jsarha@ti.com> Cc: "Tang, Jun" <jun.tang@intel.com> Reported-by: "Tang, Jun" <jun.tang@intel.com> Cc: stable@vger.kernel.org Fixes: 7f1f3851feb0 ("drm/i915: sprite support for ValleyView v4") Reviewed-by: Shashank Sharma <shashank.sharma@intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20180214192327.3250-5-ville.syrjala@linux.intel.com

In bind the psr handler gets registered first before the core analogix_dp_bind() gets called. So it should be the other way around in unbind, first unbind the analogix_dp and then unregister the psr.

2018-03-01drm/bridge: analogix: Do not use device's drvdataJeffy Chen4-69/+74
The driver that instantiates the bridge should own the drvdata, as all driver model callbacks (probe, remove, shutdown, PM ops, etc.) are also owned by its driver struct. Moreover, storing two different pointer types in driver data depending on driver initialization status is barely a good practice and in fact has led to many bugs in this driver. Let's clean up this mess and change Analogix entry points to simply accept some opaque struct pointer, adjusting their users at the same time to avoid breaking the compilation.

2018-02-26drm/pl111: Remove reverse dependency on DRM_DUMB_VGA_DACThierry Reding1-1/+0
DRM_DUMB_VGA_DAC is a user-visible symbol. Selecting it can cause unmet direct dependencies such as this (on i386, randconfig): warning: (DRM_PL111) selects DRM_DUMB_VGA_DAC which has unmet direct dependencies (HAS_IOMEM && DRM && DRM_BRIDGE && OF) This is because DRM_DUMB_VGA_DAC depends on OF while DRM_PL111 does not. It does indirectly depend on OF via the ARM and ARM64 dependencies, but since it can also be enabled under COMPILE_TEST, randconfig can find a case where DRM_PL111 is selected without pulling in OF and not meeting the dependency for DRM_DUMB_VGA_DAC. Since select is "heavy handed", DRM_DUMB_VGA_DAC is going to be enabled regardless of the above warning and causes the following build error: ../drivers/gpu/drm/bridge/dumb-vga-dac.c: In function 'dumb_vga_probe': ../drivers/gpu/drm/bridge/dumb-vga-dac.c:207:13: error: 'struct drm_bridge' has no member named 'of_node' vga->bridge.of_node = pdev->dev.of_node; See Documentation/kbuild/kconfig-language.txt, "reverse dependencies".
