5208989d - drm/tegra: Run DRM default client setup

Tue, 24 Sep 2024 07:13:16 +0000

drm/tegra: Run DRM default client setupRework fbdev probing to support fbdev_probe in struct drm_driverand remove the old fb_probe callback. Provide an initializer macrofor struct drm_driver that sets the callback according to the kernelconfiguration.Call drm_client_setup() to run the kernel's default client setupfor DRM. Set fbdev_probe in struct drm_driver, so that the clientsetup can start the common fbdev client.The tegra driver specifies a preferred color mode of 32. As thisis the default if no format has been given, leave it out entirely.v5:- select DRM_CLIENT_SELECTIONSigned-off-by: Thomas Zimmermann Cc: Thierry Reding Cc: Mikko Perttunen Cc: Jonathan Hunter Acked-by: Javier Martinez Canillas Link: https://patchwork.freedesktop.org/patch/msgid/20240924071734.98201-79-tzimmermann@suse.de List of files: /linux-6.15/drivers/gpu/drm/tegra/Kconfig
