Add support for the COLOR_RANGE property on planes. This property selects whether the input YCbCr data is to treated as limited range or full range. On most platforms this is a matter of setting the "YUV range correction disable" bit, and on VLV/CHV we'll just have to program the color correction logic to pass the data through unmodified. v2: Rebase 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: Uma Shankar <uma.shankar@intel.com> Cc: Shashank Sharma <shashank.sharma@intel.com> Cc: Jyri Sarha <jsarha@ti.com> Reviewed-by:

Add support for the COLOR_ENCODING plane property which selects the matrix coefficients used for the YCbCr->RGB conversion. Our hardware can generally handle BT.601 and BT.709. CHV pipe B sprites have a fully programmable matrix, so in theory we could handle anything, but it doesn't seem all that useful to expose anything beyond BT.601 and BT.709 at this time. GLK can supposedly do BT.2020, but let's leave enabling that for the future as well. v2: Rename bit defines to match the spec more closely (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: Uma Shankar <uma.shankar@intel.com> Cc: Shashank Sharma <shashank.sharma@intel.com> Cc: Jyri Sarha <jsarha@ti.com> Reviewed-by:

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". I'm going to assume that just means it's going to use the YCbCr->RGB matrix as specified in BT.601 and doesn't actually change the gamut.

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:

While A83T HDMI PHY seems to be just customized Synopsys HDMI PHY, H3 HDMI PHY is completely custom PHY. However, they still have many things in common like clock and reset setup, setting sync polarity and more. Add support for H3 HDMI PHY variant. While documentation exists for this PHY variant, it doesn't go in great details. Because of that, almost all settings are copied from BSP linux 4.4. Interestingly, those settings are slightly different to those found in a older BSP with Linux 3.4. For now, no user visible difference was found between them. Signed-off-by:

Current polarity configuration code is cleary wrong since it compares same flag two times. However, even if flag name is fixed, it won't work well for resolutions which have one polarity positive and another negative. Fix that by properly set each bit according to each polarity. Since those two bits are not described in any documentation, relationships were obtained by experimentation. Fixes: b7c7436a ("drm/sun4i: Implement A83T HDMI driver") Signed-off-by:

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. Signed-off-by:

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".
