drm/kmb: Use drm_module_platform_driver() to register the driver

2022-01-27T18:15:46Z

The macro calls to a DRM specific platform driver init handler that checks whether the driver is allowed to be registered or not. Signed-off-by: Javier Martinez Canillas Acked-by: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/msgid/20211217003752.3946210-12-javierm@redhat.com

drm: Remove CONFIG_DRM_KMS_CMA_HELPER option

2021-11-30T10:10:03Z

Link drm_fb_cma_helper.o into drm_cma_helper.ko if CONFIG_DRM_KMS_HELPER has been set. Remove CONFIG_DRM_KMS_CMA_HELPER config option. Selecting KMS helpers and CMA will now automatically enable CMA KMS helpers. Some drivers' Kconfig files did not correctly select KMS or CMA helpers. Fix this as part of the change.

drm/kmb: Remove clearing DPHY regs

2021-10-21T09:08:08Z

Don't clear the shared DPHY registers common to MIPI Rx and MIPI Tx during DSI initialization since this was causing MIPI Rx reset. Rest of the writes are bitwise, so will not affect Mipi Rx side.
