2020-03-18drm/core: Add drm_afbc_framebuffer and a corresponding helperAndrzej Pietrasiewicz
The new struct contains afbc-specific data. The new function can be used by drivers which support afbc to complete the preparation of struct drm_afbc_framebuffer. It must be called after allocating the said struct and calling drm_gem_fb_init_with_funcs().

2020-03-18drm/core: Allow drivers allocate a subclass of struct drm_framebufferAndrzej Pietrasiewicz
Allow allocating a specialized version of struct drm_framebuffer by moving the actual fb allocation out of drm_gem_fb_create_with_funcs(); the respective functions names are adjusted to reflect that fact. Please note, though, that standard size checks are performed on buffers, so the drm_gem_fb_init_with_funcs() is useful for cases where those standard size checks are appropriate or at least don't conflict the checks to be performed in the specialized case. Thanks to this change the drivers can call drm_gem_fb_init_with_funcs() having allocated their special version of struct drm_framebuffer, exactly the way the new version of drm_gem_fb_create_with_funcs() does.

2020-03-16drm/edid: Distribute switch variables for initializationKees Cook
Variables declared in a switch statement before any case statements cannot be automatically initialized with compiler instrumentation (as they are not part of any execution flow). With GCC's proposed automatic stack variable initialization feature, this triggers a warning (and they don't get initialized). Clang's automatic stack variable initialization (via CONFIG_INIT_STACK_ALL=y) doesn't throw a warning, but it also doesn't initialize such variables[1]. Note that these warnings (or silent skipping) happen before the dead-store elimination optimization phase, so even when the automatic initializations are later elided in favor of direct initializations, the warnings remain. To avoid these problems, lift such variables up into the next code block. drivers/gpu/drm/drm_edid.c: In function ‘drm_edid_to_eld’: drivers/gpu/drm/drm_edid.c:4395:9: warning: statement will never be executed [-Wswitch-unreachable] 4395 | int sad_count; | ^~~~~~~~~ [1] https://bugs.llvm.org/show_bug.cgi?id=44916 v2: move into function block instead being switch-local (Ville Syrjälä) Signed-off-by: Kees Cook <keescook@chromium.org> [danvet: keep the changelog] Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/202003060930.DDCCB6659@keescook

In that case current code would count that as external rgb device, which in turn would make probing the rockchip-drm device fail.

2020-03-10drm/dp_mst: Fix drm_dp_check_mstb_guid() return codeLyude Paul
We actually expect this to return a 0 on success, or negative error code on failure. In order to do that, we check whether or not we managed to write the whole GUID and then return 0 if so, otherwise return a negative error code. Also, let's add an error message here so it's a little more obvious when this fails in the middle of a link address probe. This should fix issues with certain MST hubs seemingly stopping for no reason in the middle of the link address probe process.

2020-03-10drm/dp_mst: Make drm_dp_mst_dpcd_write() consistent with drm_dp_dpcd_write()Lyude Paul
Noticed this while having some problems with hubs sometimes not being detected on the first plug. Every single dpcd read or write function returns the number of bytes transferred on success or a negative error code, except apparently for drm_dp_mst_dpcd_write() - which returns 0 on success. There's not really any good reason for this difference that I can tell, and having the two functions give differing behavior means that drm_dp_dpcd_write() will end up returning 0 on success for MST devices, but the number of bytes transferred for everything else. So, fix that and update the kernel doc.

2020-03-10drm/panel-simple: Fix dotclock for Ortustech COM37H3MH. Nikolaus Schaller
The currently listed dotclock disagrees with the currently listed vrefresh rate. Change the dotclock to match the vrefresh. There are two variants of the COM37H3M panel. The older one's COM37H3M05DTC data sheet specifies: MIN TYP MAX CLK frequency fCLK -- 22.4 26.3 MHz (in VGA mode) VSYNC Frequency fVSYNC 54 60 66 Hz VSYNC cycle time tv -- 650 -- H HSYNC frequency fHSYNC -- 39.3 -- kHz HSYNC cycle time th -- 570 -- CLK The newer one's COM37H3M99DTC data sheet says: MIN TYP MAX CLK frequency fCLK 18 19.8 27 MHz VSYNC Frequency fVSYNC 54 60 66 Hz VSYNC cycle time tv 646 650 700 H HSYNC frequency fHSYNC -- 39.0 50.0 kHz HSYNC cycle time th 504 508 630 CLK So we choose a parameter set that lies within the specs of both variants. We start at .vrefresh = 60, choose .htotal = 570 and .vtotal = 650 and end up in a clock of 22.230 MHz. Reported-by: Ville Syrjala <ville.syrjala@linux.intel.com> Signed-off-by: H.

2020-03-10drm/meson: Add YUV420 output supportNeil Armstrong
This patch adds support for the YUV420 output from the Amlogic Meson SoCs Video Processing Unit to the HDMI Controller. The YUV420 is obtained by generating a YUV444 pixel stream like the classic HDMI display modes, but then the Video Encoder output can be configured to down-sample the YUV444 pixel stream to a YUV420 stream. In addition if pixel stream down-sampling, the Y Cb Cr components must also be mapped differently to align with the HDMI2.0 specifications. This mode needs a different clock generation scheme since the TMDS PHY clock must match the 10x ratio with the YUV420 pixel clock, but the video encoder must run at 2x the pixel clock. This patch enables the bridge bus format negociation, and handles the YUV420 case if selected by the negociation.
