In prevision of adding support for YUV formats, set the YUV to RGB colorspace conversion coefficients if required and don't bypass the CSC engine when converting. The BT601 coefficients from the A33 BSP are copied over from the backend code. Because of module inter-dependency, we can't have the frontend use these coefficients from the backend directly.

Both the backend and the frontend need the BT.601 CSC coefficients for YUV to RGB conversion. Since the backend has a dependency on the frontend (and not the other way round), move the coefficients there so that both can access them without having to duplicate them. Signed-off-by:

Since all the RGB input formats have the same value for the DATA_FMT field of the INPUT_FMT register, we can group them when the format is known to be RGB. Here, we assume that a non-YUV format is RGB, because the hardware does not support any other colorspace than RGB and YUV. Use the DRM format info structure to check whether the format uses a YUV colorspace. Signed-off-by:

The helper returning the input mode needs to know the number of planes for the provided format. Passing the fourcc requires iterating through the format info list in order to return the number of planes. Pass the DRM format info structure directly instead to all helpers related to configuring the input format, since it's available to the caller. Also rename the input format in the caller function to keep things consistent. Signed-off-by:

Checking for the number of planes is not sufficient to en ensure that the format is a packed YUV422. Use explicit fourcc helpers for the check instead. Signed-off-by:

Display engine drivers often need to distinguish between different types of YUV sub-sampling. This introduces helpers to check for common sub-sampling ratios in their commonly-used denomination from the DRM format info. Signed-off-by:

Paul Kocialkowski authored
It is often useful to check whether the DRM format info retrieved from the DRM framebuffer matches a specific YUV planes disposition. This introduces helpers to quickly check that a provided format info matches a YUV format with a specific disposition, in commonly-used terminology. The intent of providing helpers taking the format info instead of the fourcc alone is to avoid the overhead of iterating through all formats when the whole format info structure is available. As a result, these helpers are very simple so they are made inline. Signed-off-by:

The name powerdown-gpios is the standard property name for the functionality covered by the previous pwdn-gpios name. This rename should be safe to do since the linux driver supporting the binding (lvds-encoder.c) never implemented the property, and no dts file names it. At least not upstream. Reviewed-by:

In file included from arch/ia64/include/asm/irqflags.h:14, from include/linux/irqflags.h:16, from include/drm/drm_util.h:35, from drivers/gpu/drm/qxl/qxl_cmd.c:28: arch/ia64/include/asm/pal.h: In function 'ia64_pal_tr_read': arch/ia64/include/asm/pal.h:1703:64: error: implicit declaration of function 'ia64_tpa'; did you mean 'ia64_pal'? [-Werror=implicit-function-declaration] PAL_CALL_PHYS_STK(iprv, PAL_VM_TR_READ, reg_num, tr_type,(u64)ia64_tpa(tr_buffer)); ^~~~~~~~ ... So we have a situation where we do not pull in <linux/types.h> when building for alpha and for ia64 we need even more definitions are required. Two invasive fixes where considered: - Change all declarations of arch_irqs_disabled_flags() to use bool - Add include of <linux/types.h> to all files that uses bool for arch_irqs_disabled_flags To invasive with a too high pain/benefit ratio, so dropped. They would not cover ia64 either. Some less invasive fixes was also considered: - Add include of <linux/types.h> to drm_util.h - Add include of <linux/interrupt.h> to drm_util.h The first was dropped as this did not cover the ia64 case. The latter was considered the best option as there could be other similar cases and we would like the header files below include/drm/ to be selfcontained. So we end up pulling in a lot of stuff not needed, but this is the price we pay in drm/ because the kernel headers are not all selfcontained. While at it, ordred the includefiles in drm_util in alphabetical order. Build tested with alpha,ia64,arm,x86 with allmodconfig and allyesconfig. v2: - fix ia64 build, changed to include interrupt.h - sort include files alphabetically Fixes: 733748ac37b45 ("drm: move drm_can_sleep() to drm_util.h") Signed-off-by:

Something that I completely missed when implementing the new MST VCPI atomic helpers is that with those helpers, there's technically a chance of us having to grab additional modeset locks in ->compute_config() and furthermore, that means we have the potential to hit a normal modeset deadlock. However, because ->compute_config() only returns a bool this means we can't return -EDEADLK when we need to drop locks and try again which means we end up just failing the atomic check permanently. Whoops. So, fix this by modifying ->compute_config() to pass down an actual error code instead of a bool so that the atomic check can be restarted on modeset deadlocks. Thanks to Ville Syrjälä for pointing this out! Changes since v1: * Add some newlines * Return only -EINVAL from hsw_crt_compute_config() * Propogate return code from intel_dp_compute_dsc_params() * Change all of the intel_dp_compute_link_config*() variants * Don't miss if (hdmi_port_clock_valid()) branch in intel_hdmi_compute_config() Signed-off-by:

On i965gm we need to adjust max_vblank_count dynamically depending on whether the TV encoder is used or not. To that end add a per-crtc max_vblank_count that takes precedence over its device wide counterpart. The driver can now call drm_crtc_set_max_vblank_count() to configure the per-crtc value before calling drm_vblank_on(). Also looks like there was some discussion about exynos needing similar treatment. v2: Drop the extra max_vblank_count!=0 check for the WARN(last!=current), will take care of it in i915 code (Daniel) WARN_ON(!inmodeset) (Daniel) WARN_ON(dev->max_vblank_count) Pimp up the docs (Daniel) Cc: stable@vger.kernel.org Cc: Inki Dae <inki.dae@samsung.com> Cc: Daniel Vetter <daniel@ffwll.ch> Signed-off-by: -

The CMA helper is already using the drm_fb_helper_generic_probe part of the generic fbdev emulation. This patch makes full use of the generic fbdev emulation by using its drm_client callbacks. This means that drm_mode_config_funcs->output_poll_changed and drm_driver->lastclose are now handled by the emulation code. Additionally fbdev unregister happens automatically on drm_dev_unregister(). The drm_fbdev_generic_setup() call is put after drm_dev_register() in the driver. This is done to highlight the fact that fbdev emulation is an internal client that makes use of the driver, it is not part of the driver as such. If fbdev setup fails, an error is printed, but the driver succeeds probing. Cc: Marek Vasut <marex@denx.de> Signed-off-by:
