2019-12-20drm/stm: ltdc: move pinctrl to encoder mode setYannick Fertré
The pin control must be set to default as soon as possible to establish a good video link between tv & bridge hdmi (encoder mode set is call before encoder enable).

2019-12-16drm/bridge/synopsys: dsi: driver-specific configuration of phy timingsHeiko Stuebner
The timing values for dw-dsi are often dependent on the used display and according to Philippe Cornu will most likely also depend on the used phy technology in the soc-specific implementation. To solve this and allow specific implementations to define them as needed add a new get_timing callback to phy_ops and call this from the dphy_timing function to retrieve the necessary values for the specific mode. Right now this handles the hs2lp + lp2hs where Rockchip SoCs need handling according to the phy speed, while STM seems to be ok with static values. changes in v5: - rebase on 5.5-rc1 - merge into px30 dsi series to prevent ordering conflicts changes in v4: - rebase to make it directly fit on top of drm-misc-next after all changes in v3: - check existence of phy_ops->get_timing in __dw_mipi_dsi_probe() - emit actual error when get_timing() call fails - add tags from Philippe and Yannick changes in v2: - add driver-specific handling, don't force all bridge users to use the same timings, as suggested by Philippe Suggested-by: Philippe Cornu <philippe.cornu@st.com> Signed-off-by: Heiko Stuebner <heiko.stuebner@theobroma-systems.com> Reviewed-by: Philippe Cornu <philippe.cornu@st.com> Tested-by: Yannick Fertre <yannick.fertre@st.com> Reviewed-by: Neil Armstrong <narmstrong@baylibre.com> Link: https://patchwork.freedesktop.org/patch/msgid/20191209143130.4553-2-heiko@sntech.de

2019-09-09drm/stm: ltdc: add pinctrl for DPI encoder modeYannick Fertré
The implementation of functions encoder_enable and encoder_disable make possible to control the pinctrl according to the encoder type. The pinctrl must be activated only if the encoder type is DPI. This helps to move the DPI-related pinctrl configuration from all the panel or bridge to the LTDC dt node.

2019-09-08drm/bridge: panel: Infer connector type from panel by defaultLaurent Pinchart
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 <laurent.pinchart@ideasonboard.com> Reviewed-by: Boris Brezillon <boris.brezillon@collabora.com> Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Link: https://patchwork.freedesktop.org/patch/msgid/20190904132804.29680-3-laurent.pinchart@ideasonboard.com

2019-05-20drm/fourcc: Pass the format_info pointer to drm_format_plane_cppMaxime Ripard
So far, the drm_format_plane_cpp function was operating on the format's fourcc and was doing a lookup to retrieve the drm_format_info structure and return the cpp. However, this is inefficient since in most cases, we will have the drm_format_info pointer already available so we shouldn't have to perform a new lookup. Some drm_fourcc functions also already operate on the drm_format_info pointer for that reason, so the API is quite inconsistent there. Let's follow the latter pattern and remove the extra lookup while being a bit more consistent. In order to be extra consistent, also rename that function to drm_format_info_plane_cpp and to a static function in the header to match the current policy.

The DRM_STM driver can be built independently of the framebuffer layer, but it causes a Kconfig warning: WARNING: unmet direct dependencies detected for FB_PROVIDE_GET_FB_UNMAPPED_AREA Depends on [n]: HAS_IOMEM [=y] && FB [=n] Selected by [y]: - DRM_STM [=y] && HAS_IOMEM [=y] && DRM [=y] && (ARCH_STM32 [=n] || ARCH_MULTIPLATFORM [=y]) Selecting FB_PROVIDE_GET_FB_UNMAPPED_AREA actually has no effect if CONFIG_FB is disabled, so we can make it a conditional 'select' instead.

2019-01-24drm: Split out drm_probe_helper.hDaniel Vetter
Having the probe helper stuff (which pretty much everyone needs) in the drm_crtc_helper.h file (which atomic drivers should never need) is confusing. Split them out. To make sure I actually achieved the goal here I went through all drivers. And indeed, all atomic drivers are now free of drm_crtc_helper.h includes. v2: Make it compile. There was so much compile fail on arm drivers that I figured I'll better not include any of the acks on v1. v3: Massive rebase because i915 has lost a lot of drmP.h includes, but not all: Through drm_crtc_helper.h > drm_modeset_helper.h -> drmP.h there was still one, which this patch largely removes. Which means rolling out lots more includes all over. This will also conflict with ongoing drmP.h cleanup by others I expect. v3: Rebase on top of atomic bochs. v4: Review from Laurent for bridge/rcar/omap/shmob/core bits: - (re)move some of the added includes, use the better include files in other places (all suggested from Laurent adopted unchanged). - sort alphabetically v5: Actually try to sort them, and while at it, sort all the ones I touch. v6: Rebase onto i915 changes. v7: Rebase once more.

2018-10-25drm/stm: Use drm_fbdev_generic_setup()Noralf Trønnes
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. drm_fbdev_generic_setup() handles mode_config.num_connector being zero. In that case it retries fbdev setup on the next .output_poll_changed.

Add mode_valid() function to filter modes according to available pll clock values and "preferred" modes. It is particularly useful for hdmi modes that require precise pixel clocks. Note that "preferred" modes are always accepted: - this is important for panels because panel clock tolerances are bigger than hdmi ones and there is no reason to not accept them (the fps may vary a little but it is not a problem). - the hdmi preferred mode will be accepted too, but userland will be able to use others hdmi "valid" modes if necessary.
