Map DRM FourCC codes to pixel descriptions with an internal struct type. Avoid simplefb's struct simplefb_format, which is for parsing "simple-framebuffer" DT nodes. Drop the unsupported formats with alpha channel from the list. The HDLCD drivers uses struct simplefb_format and its default initializer SIMPLEFB_FORMATS to map DRM_FORMAT_ constants to pixel descriptions. The simplefb helpers are for parsing "simple-framebuffer" DT nodes and should be avoided in other context. Therefore replace it in hdlcd with a custom struct type and pixel descriptions from PIXEL_FORMAT_ constants. This change also removes including <linux/platform_data/simplefb.h>, which includes several unrelated headers, such as <linux/fb.h>. v2: - drop unsupported alpha formats (Liviu) - keep original sorting of formats (Javier) - use anonymous type for supported_formats Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Javier Martinez Canillas <javierm@redhat.com> Reviewed-by: Liviu Dudau <liviu.dudau@arm.com> Link: https://lore.kernel.org/r/20250610073027.322944-1-tzimmermann@suse.de
