Revert "drm: atmel-hlcdc: enable sys_clk during initalization."

2020-01-06T18:54:27+00:00

This reverts commit d2c755e66617620b729041c625a6396c81d1231c ("drm: atmel-hlcdc: enable sys_clk during initalization."). With commit "drm: atmel-hlcdc: enable clock before configuring timing engine" there is no need for this patch. Code is also simpler.

drm: atmel-hlcdc: prefer a lower pixel-clock than requested

2020-01-06T18:54:27+00:00

The intention was to only select a higher pixel-clock rate than the requested, if a slight overclocking would result in a rate significantly closer to the requested rate than if the conservative lower pixel-clock rate is selected. The fixed patch has the logic the other way around and actually prefers the higher frequency. Fix that.

drm: atmel-hlcdc: enable clock before configuring timing engine

2020-01-06T18:53:24+00:00

Changing pixel clock source without having this clock source enabled will block the timing engine and the next operations after (in this case setting ATMEL_HLCDC_CFG(5) settings in atmel_hlcdc_crtc_mode_set_nofb() will fail). It is recomended (although in datasheet this is not present) to actually enabled pixel clock source before doing any changes on timing enginge (only SAM9X60 datasheet specifies that the peripheral clock and pixel clock must be enabled before using LCD controller).

drm: atmel-hlcdc: use double rate for pixel clock only if supported

2020-01-06T18:52:53+00:00

Doubled system clock should be used as pixel cock source only if this is supported. This is emphasized by the value of atmel_hlcdc_crtc::dc::desc::fixed_clksrc.

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

2019-09-08T17:04:23+00:00

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
