drm/simple-kms: Standardize arguments for callbacks

2019-10-24T11:55:56Z

Passing the wrong type feels icky, everywhere else we use the pipe as the first parameter.

drm/bridge: panel: Infer connector type from panel by default

2019-09-08T17:04:23Z

The drm panel bridge creates a connector using a connector type explicitly passed by the display controller or bridge driver that instantiates the panel bridge. Now that drm_panel reports its connector type, we can use it to avoid passing an explicit (and often incorrect) connector type to drm_panel_bridge_add() and devm_drm_panel_bridge_add(). Several drivers report incorrect or unknown connector types to userspace. Reporting a different type may result in a breakage. For that reason, rename (devm_)drm_panel_bridge_add() to (devm_)drm_panel_bridge_add_typed(), and add new (devm_)drm_panel_bridge_add() functions that use the panel connector type. Update all callers of (devm_)drm_panel_bridge_add() to the _typed function, they will be converted one by one after testing. The panel drivers have been updated with the following Coccinelle semantic patch, with manual inspection and fixes to indentation. @@ expression bridge; expression dev; expression panel; identifier type; @@ ( -bridge = drm_panel_bridge_add(panel, type); +bridge = drm_panel_bridge_add_typed(panel, type); | -bridge = devm_drm_panel_bridge_add(dev, panel, type); +bridge = devm_drm_panel_bridge_add_typed(dev, panel, type); ) Signed-off-by: Laurent Pinchart Reviewed-by: Boris Brezillon Signed-off-by: Sam Ravnborg Link: https://patchwork.freedesktop.org/patch/msgid/20190904132804.29680-3-laurent.pinchart@ideasonboard.com

drm/pl111: Support grayscale

2019-08-09T07:15:05Z

Migrating the TI nspire calculators to use the PL111 driver for framebuffer requires grayscale support for the elder panel which uses 8bit grayscale only. DRM does not support 8bit grayscale framebuffers in memory, but by defining the bus format to be MEDIA_BUS_FMT_Y8_1X8 we can get the hardware to turn on a grayscaling feature and convert the RGB framebuffer to grayscale for us.

drm/pl111: Drop special pads config check

2019-08-03T09:59:54Z

This drops the check of the surplus "pads" configuration from the device tree that is completely unused in the DRM driver. This was only used to work around limitations in the earlier fbdev driver.

drm/pl111: pl111_vexpress.c: Add of_node_put() before return

2019-07-15T23:26:43Z

Each iteration of for_each_available_child_of_node puts the previous node, but in the case of a break from the middle of the loop there is no put, thus causing a memory leak. Hence add an of_node_put before the break. Issue found with Coccinelle.

Split out to make the functional changes stick out more. All places where DRIVER_PRIME was used have been removed in previous patches already. v2: amdgpu gained DRIVER_SYNCOBJ_TIMELINE. v3: amdgpu lost DRIVER_SYNCOBJ_TIMELINE. v4: Don't add a space in i915_drv.c (Sam) v5: Add note that previous patches removed all the DRIVER_PRIME users already (Emil). v6: Fixupe ingenic (new driver) while applying.
