Call drm_client_setup() to run the kernel's default client setup for DRM. Set fbdev_probe in struct drm_driver, so that the client setup can start the common fbdev client. The hdlcd driver specifies a preferred color mode of 32. As this is the default if no format has been given, leave it out entirely. v5: - select DRM_CLIENT_SELECTION Signed-off-by: Thomas Zimmermann <tzimmermann@xxxxxxx> Cc: Liviu Dudau <liviu.dudau@xxxxxxx> Acked-by: Liviu Dudau <liviu.dudau@xxxxxxx> --- drivers/gpu/drm/arm/Kconfig | 1 + drivers/gpu/drm/arm/hdlcd_drv.c | 4 +++- 2 files changed, 4 insertions(+), 1 deletion(-) diff --git a/drivers/gpu/drm/arm/Kconfig b/drivers/gpu/drm/arm/Kconfig index ddf20708370f..ed218e5f7901 100644 --- a/drivers/gpu/drm/arm/Kconfig +++ b/drivers/gpu/drm/arm/Kconfig @@ -6,6 +6,7 @@ config DRM_HDLCD tristate "ARM HDLCD" depends on DRM && OF && (ARM || ARM64 || COMPILE_TEST) depends on COMMON_CLK + select DRM_CLIENT_SELECTION select DRM_KMS_HELPER select DRM_GEM_DMA_HELPER help diff --git a/drivers/gpu/drm/arm/hdlcd_drv.c b/drivers/gpu/drm/arm/hdlcd_drv.c index 32be9e370049..f5d358f3893b 100644 --- a/drivers/gpu/drm/arm/hdlcd_drv.c +++ b/drivers/gpu/drm/arm/hdlcd_drv.c @@ -23,6 +23,7 @@ #include <drm/drm_aperture.h> #include <drm/drm_atomic_helper.h> +#include <drm/drm_client_setup.h> #include <drm/drm_crtc.h> #include <drm/drm_debugfs.h> #include <drm/drm_drv.h> @@ -228,6 +229,7 @@ DEFINE_DRM_GEM_DMA_FOPS(fops); static const struct drm_driver hdlcd_driver = { .driver_features = DRIVER_GEM | DRIVER_MODESET | DRIVER_ATOMIC, DRM_GEM_DMA_DRIVER_OPS, + DRM_FBDEV_DMA_DRIVER_OPS, .fops = &fops, .name = "hdlcd", .desc = "ARM HDLCD Controller DRM", @@ -299,7 +301,7 @@ static int hdlcd_drm_bind(struct device *dev) if (ret) goto err_register; - drm_fbdev_dma_setup(drm, 32); + drm_client_setup(drm, NULL); return 0; -- 2.46.0
