2020-07-14drm/tilcdc: Use standard drm_atomic_helper_commitDaniel Vetter
Gives us proper nonblocking support for free, and a pile of other things. The tilcdc code is simply old enough that it was never converted over, but was stuck forever with the copypasta from when it was initially merged. The riskiest thing with this conversion is maybe that there's an issue with the vblank handling or vblank event handling, which will upset the modern commit support in atomic helpers. But from a cursory review drm_crtc_vblank_on/off is called in the right places, and the event handling also seems to exist (albeit with much hand-rolling and probably some races, could perhaps be converted over to drm_crtc_arm_vblank_event without any real loss). Motivated by me not having to hand-roll the dma-fence annotations for this. v2: Clear out crtc_state->event when we're handling the event, to avoid upsetting the helpers (reported by Jyri). v3: Also send out even whent the crtc is getting disabled. Tilcdc looks a bit like conversion to simple display helpers would work out really nice.

2020-03-18drm: convert .debugfs_init() hook to return void.Wambui Karuga
As a result of commit 987d65d01356 (drm: debugfs: make drm_debugfs_create_files() never fail) and changes to various debugfs functions in drm/core and across various drivers, there is no need for the drm_driver.debugfs_init() hook to have a return value. Therefore, declare it as void. This also includes refactoring all users of the .debugfs_init() hook to return void across the subsystem. v2: include changes to the hook and drivers that use it in one patch to prevent driver breakage and enable individual successful compilation of this change.

2020-02-26drm/bridge: Extend bridge API to disable connector creationLaurent Pinchart
Most bridge drivers create a DRM connector to model the connector at the output of the bridge. This model is historical and has worked pretty well so far, but causes several issues: - It prevents supporting more complex display pipelines where DRM connector operations are split over multiple components. For instance a pipeline with a bridge connected to the DDC signals to read EDID data, and another one connected to the HPD signal to detect connection and disconnection, will not be possible to support through this model. - It requires every bridge driver to implement similar connector handling code, resulting in code duplication. - It assumes that a bridge will either be wired to a connector or to another bridge, but doesn't support bridges that can be used in both positions very well (although there is some ad-hoc support for this in the analogix_dp bridge driver). In order to solve these issues, ownership of the connector should be moved to the display controller driver (where it can be implemented using helpers provided by the core). Extend the bridge API to allow disabling connector creation in bridge drivers as a first step towards the new model. The new flags argument to the bridge .attach() operation allows instructing the bridge driver to skip creating a connector. Unconditionally set the new flags argument to 0 for now to keep the existing behaviour, and modify all existing bridge drivers to return an error when connector creation is not requested as they don't support this feature yet. The change is based on the following semantic patch, with manual review and edits. @ rule1 @ identifier funcs; identifier fn; @@ struct drm_bridge_funcs funcs = { ..., .attach = fn }; @ depends on rule1 @ identifier rule1.fn; identifier bridge; statement S, S1; @@ int fn( struct drm_bridge *bridge + , enum drm_bridge_attach_flags flags ) { ... when != S + if (flags & DRM_BRIDGE_ATTACH_NO_CONNECTOR) { + DRM_ERROR("Fix bridge driver to make connector optional!"); + return -EINVAL; + } + S1 ... } @ depends on rule1 @ identifier rule1.fn; identifier bridge, flags; expression E1, E2, E3; @@ int fn( struct drm_bridge *bridge, enum drm_bridge_attach_flags flags ) { <... drm_bridge_attach(E1, E2, E3 + , flags ) ...> } @@ expression E1, E2, E3; @@ drm_bridge_attach(E1, E2, E3 + , 0 ) Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Boris Brezillon <boris.brezillon@collabora.com> Acked-by: Sam Ravnborg <sam@ravnborg.org> Reviewed-by: Tomi Valkeinen <tomi.valkeinen@ti.com> Tested-by: Sebastian Reichel <sebastian.reichel@collabora.com> Reviewed-by: Sebastian Reichel <sebastian.reichel@collabora.com> Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200226112514.12455-10-laurent.pinchart@ideasonboard.com

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.

2019-08-28drm: Stop including drm_bridge.h from drm_crtc.hBoris Brezillon
We are about to add a drm_bridge_state that inherits from drm_private_state which is defined in drm_atomic.h. Problem is, drm_atomic.h includes drm_crtc.h which in turn includes drm_bridge.h, leading to "drm_private_state has incomplete type" error.

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.

2018-11-01drm/tilcdc: 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.

This fixes setting the clock divider on the TI OMAP-L138 LCDK board. The clock drivers for OMAP-L138 are being covernted to the common clock framework. When this happens, clk_set_rate() will no longer return an error. However, on this SoC, the clock rate cannot actually be changed because the clock has to maintain a fixed ratio to the ARM clock. So after attempting to set the clock rate, we need to check to see if the new rate is actually close enough. If not, then follow the previous error path to adjust the divider in LCDC IP block to compensate for not being able to change the parent clock rate. Tested working on a TI OMAP-L138 LCDK board.
