The fsl dcu now uses the clk-provider interfaces, which are not available when CONFIG_COMMON_CLK is disabled:
drivers/gpu/drm/fsl-dcu/fsl_dcu_drm_drv.c: In function 'fsl_dcu_drm_probe': drivers/gpu/drm/fsl-dcu/fsl_dcu_drm_drv.c:362:20: error: implicit declaration of function '__clk_get_name' [-Werror=implicit-function-declaration] pix_clk_in_name = __clk_get_name(pix_clk_in);
This adds a Kconfig dependency to prevent the driver from being enabled in this case.
