[ Upstream commit 127367ad2e0f4870de60c6d719ae82ecf68d674c ] Three clocks are not being released in devm_regmap_init_mmio() error path. Add proper goto and set ret to the error code.

drm/sun4i: Fix layer zpos change/atomic modesetting

2024-06-10T10:44:41+00:00

Identical configurations of planes can lead to different (and wrong) layer -> pipe routing at HW level, depending on the order of atomic plane changes. For example: - Layer 1 is configured to zpos 0 and thus uses pipe 0. No other layer is enabled. This is a typical situation at boot. - When a compositor takes over and layer 3 is enabled, sun8i_ui_layer_enable() will get called with old_zpos=0 zpos=1, which will lead to incorrect disabling of pipe 0 and enabling of pipe 1. What happens is that sun8i_ui_layer_enable() function may disable blender pipes even if it is no longer assigned to its layer. To correct this, move the routing setup out of individual plane's atomic_update into crtc's atomic_update, where it can be calculated and updated all at once. Remove the atomic_disable callback because it is no longer needed.

drm/sun4i: Unify sun8i_*_layer structs

2024-06-10T10:44:40+00:00

These structs are identical, use a single struct to represent private data for the DRM plane. This is a preparation for configuring layer routing from the CRTC (mixer) instead of current approach of setting up routing from individual layer's atomic_update callback.

Commit ea64761a54a2 ("drm/sun4i: hdmi: Switch to HDMI connector") introduced a dependency that got renamed in a previous version, but wasn't properly updated in that driver.

Revert "drm: Make drivers depends on DRM_DW_HDMI"

2024-05-02T15:59:59+00:00

This reverts commit c0e0f139354c01e0213204e4a96e7076e5a3e396, as helper code should always be selected by the driver that needs it, for the convenience of the final user configuring a kernel. The user who configures a kernel should not need to know which helpers are needed for the driver he is interested in. Making a driver depend on helper code means that the user needs to know which helpers to enable first, which is very user-unfriendly.
