2024-05-02Revert "drm: Make drivers depends on DRM_DW_HDMI"Geert Uytterhoeven
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.

2023-10-16drm: renesas: shmobile: Turn vblank on/off when enabling/disabling CRTCGeert Uytterhoeven
The DRM core vblank handling mechanism requires drivers to forcefully turn vblank reporting off when disabling the CRTC, and to restore the vblank reporting status when enabling the CRTC. Implement this using the drm_crtc_vblank_{on,off}() helpers. Note that drm_crtc_vblank_off() must be called at startup to synchronize the state of the vblank core code with the hardware, which is initially disabled. This is performed at CRTC creation time, requiring vertical blank initialization to be moved before creating CRTCs.

2023-10-16drm: renesas: shmobile: Remove custom plane destroy callbackGeert Uytterhoeven
There is no need to call drm_plane_force_disable() from the plane's .destroy() callback, as the plane should have been disabled already before. See also commit 3c858a33858baa8c ("drm/plane_helper: don't disable plane in destroy function") for the generic plane helper case. After removing this call, shmob_drm_plane_destroy() becomes a simple wrapper around shmob_drm_plane_destroy(), hence replace it by the latter.

2023-10-16drm: renesas: shmobile: Add support for Runtime PMGeert Uytterhoeven
The SH-Mobile LCD Controller is part of a PM Domain on all relevant SoCs (clock domain on all, power domain on some). Hence it may not be sufficient to manage the LCDC module clock explicitly (e.g. if the selected clock source differs from SHMOB_DRM_CLK_BUS). Fix this by using Runtime PM for all clock handling. Add an explicit dependency on CONFIG_PM, which should already be met on all affected platforms.

2023-10-16drm: renesas: shmobile: Fix ARGB32 overlay format typoGeert Uytterhoeven
When configuring a CHn Source Image Format Register (LDBBSIFR), one should use the corresponding LDBBSIFR_RPKF_* definition for overlay planes, not the DDFR_PKF_* definition for the primary plane. Fortunately both definitions resolve to the same value, so this bug did not cause any harm.

2023-10-16drm: renesas: shmobile: Fix overlay plane disableGeert Uytterhoeven
Merely writing zero to the CHn Source Image Format Register is not sufficient to disable a plane, as the programmed register value is not propagated immediately to the current side. This can be seen when using the -P option of modetest: the extra plane is displayed correctly, but does not disappear after exit. Fix this by doing the full update dance using the Blend Control Register, like is done when enabling the plane.
