2023-10-16drm: renesas: shmobile: Add DT supportGeert Uytterhoeven4-16/+74
Add DT support, by: 1. Creating a panel bridge from DT, and attaching it to the encoder, 2. Replacing the custom connector with a bridge connector, 3. Obtaining clock configuration based on the compatible value. Note that for now the driver uses a fixed clock configuration selecting the bus clock, as the current code to select other clock inputs needs changes to support any other SoCs than SH7724.

2023-10-16drm: renesas: shmobile: Remove internal CRTC state trackingGeert Uytterhoeven2-58/+11
Now the suspend/resume methods no longer need to look at internal driver state, the dpms and started fields in the shmob_drm_crtc structure can be removed, as well as the shmob_drm_crtc_dpms() wrapper. After this, shmob_drm_crtc_atomic_{en,dis}able() became just wrappers around shmob_drm_crtc_st{art,op}(), so inline the latter.

2023-10-16drm: renesas: shmobile: Turn vblank on/off when enabling/disabling CRTCGeert Uytterhoeven2-7/+15
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.

2023-09-09drm/shmobile: Convert to platform remove callback returning voidUwe Kleine-König1-4/+2
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

The (large) rcar_du_modeset_init() function can fail for many reasons, two of two involving probe deferral. Use dev_err_probe() in those code paths to record the cause of the probe deferral, in order to help debugging probe issues.

2023-07-21drm: Explicitly include correct DT includesRob Herring5-3/+4
The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.
