On SDM845 and SC7180 DSI needs to express a performance state requirement on a power domain depending on the clock rates. Use OPP table from DT to register with OPP framework and use dev_pm_opp_set_rate() to set the clk/perf state. dev_pm_opp_set_rate() is designed to be equivalent to clk_set_rate() for devices without an OPP table, hence the change works fine on devices/platforms which only need to set a clock rate.

2020-07-30drm/msm/dpu: ensure device suspend happens during PM sleepKalyan Thota1-0/+2
"The PM core always increments the runtime usage counter before calling the ->suspend() callback and decrements it after calling the ->resume() callback" DPU and DSI are managed as runtime devices. When suspend is triggered, PM core adds a refcount on all the devices and calls device suspend, since usage count is already incremented, runtime suspend was not getting called and it kept the clocks on which resulted in target not entering into XO shutdown. Add changes to force suspend on runtime devices during pm sleep. Changes in v1: - Remove unnecessary checks in the function _dpu_kms_disable_dpu (Rob Clark). Changes in v2: - Avoid using suspend_late to reset the usagecount as suspend_late might not be called during suspend call failures (Doug). Changes in v3: - Use force suspend instead of managing device usage_count via runtime put and get API's to trigger callbacks (Doug). Changes in v4: - Check the return values of pm_runtime_force_suspend and pm_runtime_force_resume API's and pass appropriately (Doug). Changes in v5: - With v4 patch, test cycle has uncovered issues in device resume. On bubs: cmd tx failures were seen as SW is sending panel off commands when the dsi resources are turned off. Upon suspend, DRM driver will issue a NULL composition to the dpu, followed by turning off all the HW blocks. v5 changes will serialize the NULL commit and resource unwinding by handling them under PM prepare and PM complete phases there by ensuring that clks are on when panel off commands are being processed. Changes in v6: - Use drm_mode_config_helper_suspend/resume() instead of legacy API drm_atomic_helper_suspend/resume() (Doug). Trigger runtime callbacks from the suspend/resume call to turn off the resources. Changes in v7: - Add "__maybe_unused" to the functions to avoid compilation failures.

2020-02-26drm/bridge: Extend bridge API to disable connector creationLaurent Pinchart1-2/+2
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 <[email protected]> Reviewed-by: Boris Brezillon <[email protected]> Acked-by: Sam Ravnborg <[email protected]> Reviewed-by: Tomi Valkeinen <[email protected]> Tested-by: Sebastian Reichel <[email protected]> Reviewed-by: Sebastian Reichel <[email protected]> Acked-by: Daniel Vetter <[email protected]> Signed-off-by: Tomi Valkeinen <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]

git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk updates from Stephen Boyd: "There are a few changes to the core framework this time around, in addition to the normal collection of driver updates to support new SoCs, fix incorrect data, and convert various drivers to clk_hw based APIs. In the core, we allow clk_ops::init() to return an error code now so that we can fail clk registration if the callback does something like fail to allocate memory. We also add a new "terminate" clk_op so that things done in clk_ops::init() can be undone, e.g. free memory. We also spit out a warning now when critical clks fail to enable and we support changing clk rates and enable/disable state through debugfs when developers compile the kernel themselves. On the driver front, we get support for what seems like a lot of Qualcomm and NXP SoCs given that those vendors dominate the diffstat. There are a couple new drivers for Xilinx and Amlogic SoCs too. The updates are all small things like fixing the way glitch free muxes switch parents, avoiding div-by-zero problems, or fixing data like parent names. See the updates section below for more details. Finally, the "basic" clk types have been converted to support specifying parents with clk_hw pointers. This work includes an overhaul of the fixed-rate clk type to be more modern by using clk_hw APIs.

2020-01-06clk: mux: Add support for specifying parents via DT/pointersStephen Boyd2-4/+4
After commit fc0c209c147f ("clk: Allow parents to be specified without string names") we can use DT or direct clk_hw pointers to specify parents. Create a generic function that shouldn't be used very often to encode the multitude of ways of registering a mux clk with different parent information. Then add a bunch of wrapper macros that only pass down what needs to be passed down to the generic function to support this with less arguments. Note: the msm drm driver passes an anonymous array through the macro which seems to confuse my compiler. Adding a parenthesis around the whole thing at the call site seems to fix it but it must be wrong. Maybe it's better to split this patch and pick out the array bits there?

2020-01-02drm/msm/dsi: Delay drm_panel_enable() until dsi_mgr_bridge_enable()Stephan Gerhold1-21/+41
At the moment, the MSM DSI driver calls drm_panel_enable() rather early from the DSI bridge pre_enable() function. At this point, the encoder (e.g. MDP5) is not enabled, so we have not started transmitting video data. However, the drm_panel_funcs documentation states that enable() should be called on the panel *after* video data is being transmitted: The .prepare() function is typically called before the display controller starts to transmit video data. [...] After the display controller has started transmitting video data, it's safe to call the .enable() function. This will typically enable the backlight to make the image on screen visible. Calling drm_panel_enable() too early causes problems for some panels: The TFT LCD panel used in the Samsung Galaxy Tab A 9.7 (2015) (APQ8016) uses the MIPI_DCS_SET_DISPLAY_BRIGHTNESS command to control backlight/brightness of the screen. The enable sequence is therefore: drm_panel_enable() drm_panel_funcs.enable(): backlight_enable() backlight_ops.update_status(): mipi_dsi_dcs_set_display_brightness(dsi, bl->props.brightness); The panel seems to silently ignore the MIPI_DCS_SET_DISPLAY_BRIGHTNESS command if it is sent too early. This prevents setting the initial brightness, causing the display to be enabled with minimum brightness instead. Adding various delays in the panel initialization code does not result in any difference. On the other hand, moving drm_panel_enable() to dsi_mgr_bridge_enable() fixes the problem, indicating that the panel requires the video stream to be active before the brightness command is accepted. Therefore: Move drm_panel_enable() to dsi_mgr_bridge_enable() to delay calling it until video data is being transmitted. Move drm_panel_disable() to dsi_mgr_bridge_disable() for similar reasons. (This is not strictly required for the panel affected above...)

To facilitate moving connector creation to display drivers, decouple the drm_connector from drm_panel. This patch adds a connector argument to drm_panel_get_modes(). All users of drm_panel_get_modes() already had the connector available, so updating users was trivial. With this patch drm_panel no longer keeps a reference to the drm_connector.

2019-10-11drm/msm/dsi: Implement reset correctlyJeffrey Hugo1-2/+4
On msm8998, vblank timeouts are observed because the DSI controller is not reset properly, which ends up stalling the MDP. This is because the reset logic is not correct per the hardware documentation. The documentation states that after asserting reset, software should wait some time (no indication of how long), or poll the status register until it returns 0 before deasserting reset. wmb() is insufficient for this purpose since it just ensures ordering, not timing between writes. Since asserting and deasserting reset occurs on the same register, ordering is already guaranteed by the architecture, making the wmb extraneous. Since we would define a timeout for polling the status register to avoid a possible infinite loop, lets just use a static delay of 20 ms, since 16.666 ms is the time available to process one frame at 60 fps.
