2025-07-14drm/bridge: Pass down connector to drm bridge detect hookAndy Yan
In some application scenarios, we hope to get the corresponding connector when the bridge's detect hook is invoked. In most cases, we can get the connector by drm_atomic_get_connector_for_encoder if the encoder attached to the bridge is enabled, however there will still be some scenarios where the detect hook of the bridge is called but the corresponding encoder has not been enabled yet. For instance, this occurs when the device is hot plug in for the first time. Since the call to bridge's detect is initiated by the connector, passing down the corresponding connector directly will make things simpler.

2025-07-08drm/rockchip: vop2: Fix the update of LAYER/PORT select registers when there ↵Andy Yan
are multi display output on rk3588/rk3568 The all video ports of rk3568/rk3588 share the same OVL_LAYER_SEL and OVL_PORT_SEL registers, and the configuration of these two registers can be set to take effect when the vsync signal arrives at a certain Video Port. If two threads for two display output choose to update these two registers simultaneously to meet their own plane adjustment requirements(change plane zpos or switch plane from one crtc to another), then no matter which Video Port'svsync signal we choose to follow for these two registers, the display output of the other Video Port will be abnormal. This is because the configuration of this Video Port does not take effect at the right time (its configuration should take effect when its VSYNC signal arrives). In order to solve this problem, when performing plane migration or change the zpos of planes, there are two things to be observed and followed: 1. When a plane is migrated from one VP to another, the configuration of the layer can only take effect after the Port mux configuration is enabled. 2. When change the zpos of planes, we must ensure that the change for the previous VP takes effect before we proceed to change the next VP. Otherwise, the new configuration might overwrite the previous one for the previous VP, or it could lead to the configuration of the previous VP being take effect along with the VSYNC of the new VP. This issue only occurs in scenarios where multi-display output is enabled.

2025-07-08drm/rockchip: vop2: fail cleanly if missing a primary plane for a video-portHeiko Stuebner
Each window of a vop2 is usable by a specific set of video ports, so while binding the vop2, we look through the list of available windows trying to find one designated as primary-plane and usable by that specific port. The code later wants to use drm_crtc_init_with_planes with that found primary plane, but nothing has checked so far if a primary plane was actually found. For whatever reason, the rk3576 vp2 does not have a usable primary window (if vp0 is also in use) which brought the issue to light and ended in a null-pointer dereference further down. As we expect a primary-plane to exist for a video-port, add a check at the end of the window-iteration and fail probing if none was found.

RK3588 integrates the Analogix eDP 1.3 TX controller IP and the HDMI/eDP TX Combo PHY based on a Samsung IP block. There are also two independent eDP display interface with different address on RK3588 Soc. The patch currently adds only the basic support, specifically RGB output up to 4K@60Hz, without the tests for audio, PSR and other eDP 1.3 specific features. In additon, the above Analogix IP has always been utilized as eDP on Rockchip platform, despite its capability to also support the DP v1.2. Therefore, the newly added logs will contain the term 'edp' rather than 'dp'. And the newly added 'apb' reset control is to ensure the APB bus of eDP controller works well on the RK3588 SoC.

2025-03-04drm/rockchip: lvds: Hide scary error messages on probe deferralHeiko Stuebner
Commit 52d11c863ac9 ("drm/rockchip: lvds: do not print scary message when probing defer") already started hiding scary messages that are not relevant if the requested supply just returned EPROBE_DEFER, but there are more possible sources - like the phy. So modernize the whole logging in the probe path by replacing the remaining deprecated DRM_DEV_ERROR with appropriate dev_err(_probe) and drm_err calls. The distinction here is that all messages talking about mishaps of the lvds element use dev_err(_probe) while messages caused by interaction with the main Rockchip drm-device use drm_err.

2025-03-04drm/rockchip: lvds: move pclk preparation in with clk_getHeiko Stuebner
The LVDS block needs a separate pclk only on some socs, so currently requests and prepares it in the soc-specific probe function, but common code is required to unprepare it in the error path or on driver remove. While this works because clk_unprepare just does nothing if clk is NULL, this mismatch of who is responsible still is not very nice. The clock-framework already has a helper for clk-get-and-prepare even with devres support in devm_clk_get_prepared(). This will get and prepare the clock and also unprepare it on driver removal, saving the driver from having to handle it "manually".

Convert drm_err(hdmi, ...) to dev_err(hdmi->dev, ...). This matches current usage, but drops "[drm] *ERROR*" prefix from logging.

2025-03-02drm/rockchip: vop2: use devm_regmap_field_alloc for cluster-regsAndy Yan
Right now vop2_cluster_init() copies the base vop2_cluster_regs and adapts the reg value with the current window's offset before adding the fields to the regmap. This conflicts with the notion of reg_fields being const, see https://lore.kernel.org/all/20240706-regmap-const-structs-v1-1-d08c776da787@weissschuh.net/ for reference, which now causes checkpatch to actually warn about that. So instead of creating one big copy and changing it afterwards, add the reg_fields individually using devm_regmap_field_alloc(). Functional it is the same, just that the reg_field we're handling can stay const.

2025-02-27drm/rockchip: Fix shutdown when no drm-device is set upHeiko Stuebner
When the drm-driver probes, it mainly creates the component device, where all the sub-drivers (vops, hdmi, etc) hook into. This will cause the shutdown handler to get called on shutdown, even though the drm-device might not have been set up, or the component bind might have failed. So use the new component helper to check whether the drm-device is up and only then call the drm-atomic helper to release all the drm magic. This prevents failures when the drm-device is never set, or has been freed up already for example by a probe-defer during the component bind.
