drm: allow passing possible_crtcs to drm_writeback_connector_init()

2022-05-01T23:12:59+00:00

Clients of drm_writeback_connector_init() initialize the possible_crtcs and then invoke the call to this API. To simplify things, allow passing possible_crtcs as a parameter to drm_writeback_connector_init() and make changes to the other drm drivers to make them compatible with this change. changes in v2: - split the changes according to their functionality changes in v3: - allow passing possible_crtcs for existing users of drm_writeback_connector_init() - squash the vendor changes into the same commit so that each patch in the series can compile individually changes in v4: - keep only changes related to possible_crtcs - add line breaks after ARRAY_SIZE - stop using temporary variables for possible_crtcs changes in v5: - None changes in v6: - None changes in v7: - wrap long lines to match the coding style of existing drivers - Fix indentation and remove parenthesis where not needed - use u32 instead of uint32_t for possible_crtcs Signed-off-by: Abhinav Kumar Acked-by: Liviu Dudau Reviewed-by: Dmitry Baryshkov Reviewed-by: Laurent Pinchart Patchwork: https://patchwork.freedesktop.org/patch/483501/ Link: https://lore.kernel.org/r/1650984096-9964-2-git-send-email-quic_abhinavk@quicinc.com Signed-off-by: Dmitry Baryshkov

drm-misc-next for v5.18: UAPI Changes: Cross-subsystem Changes: - Improve performance of some fbdev ops, in some cases up to 6x faster. Core Changes: - Some small DP fixes. - Find panels in subnodes of OF devices, and add of_get_drm_panel_display_mode to retrieve mode. - Add drm_object_property_get_default_value and use it for resetting zpos in plane state reset, removing the need for individual drivers to do it. - Same for color encoding and color range props. - Update panic handling todo doc. - Add todo that format conversion helpers should be sped up similarly to fbdev ops. Driver Changes: - Add panel orientation property to simpledrm for quirked panels. - Assorted small fixes to tiny/repaper, nouveau, stm, omap, ssd130x. - Add crc support to stm/ltdc. - Add MIPI DBI compatible SPI driver - Assorted small fixes to tiny panels and bridge drivers. - Add AST2600 support to aspeed.

drm: rcar-du: Don't restart group when enabling plane on Gen3

2022-03-03T12:06:04+00:00

On Gen3 hardware enabling a VSP plane doesn't change any register that requires DRES to take effect. Avoid a group restart in that case. Signed-off-by: Laurent Pinchart Reviewed-by: Kieran Bingham

drm: rcar-du: Drop LVDS device tree backward compatibility

2022-03-03T09:26:35+00:00

The rcar-du driver goes to great lengths to preserve device tree backward compatibility for the LVDS encoders by patching old device trees at runtime. The last R-Car Gen2 platform was converted to the new bindings commit edb0c3affe5214a2 ("ARM: dts: r8a7793: Convert to new LVDS DT bindings"), in v4.17, and the last RZ/G1 platform converted in commit 6a6a797625b5fe85 ("ARM: dts: r8a7743: Convert to new LVDS DT bindings"), in v5.0. Both are older than commit 58256143cff7c2e0 ("clk: renesas: Remove R-Car Gen2 legacy DT clock support"), in v5.5, which removes support for legacy bindings for clocks. The LVDS compatibility code is thus not needed anymore. Drop it. Signed-off-by: Laurent Pinchart Reviewed-by: Kieran Bingham

drm/rcar: plane: Remove redundant zpos initialisation

2022-02-25T16:57:01+00:00

The rcar-du KMS driver will call drm_plane_create_zpos_property() with an init value depending on the plane type. Since the initial value wasn't carried over in the state, the driver had to set it again in rcar_du_plane_reset() and rcar_du_vsp_plane_reset(). However, the helpers have been adjusted to set it properly at reset, so this is not needed anymore.

drm: rcar-du: Add support for the nomodeset kernel parameter

2022-01-27T18:15:50+00:00

According to disable Documentation/admin-guide/kernel-parameters.txt, this parameter can be used to disable kernel modesetting. DRM drivers will not perform display-mode changes or accelerated rendering and only the system framebuffer will be available if it was set-up. But only a few DRM drivers currently check for nomodeset, make this driver to also support the command line parameter.
