drm: add an fb creation ioctl that takes a pixel format v5
To properly support the various plane formats supported by different hardware, the kernel must know the pixel format of a framebuffer object. So add a new ioctl taking a format argument corresponding to a fourcc name from the new drm_fourcc.h header file. Implement the fb creation hooks in terms of the new mode_fb_cmd2 using helpers where the old bpp/depth values are needed. v2: create DRM specific fourcc header file for sharing with libdrm etc v3: fix rebase failure and use DRM fourcc codes in intel_display.c and update commit message v4: make fb_cmd2 handle field into an array for multi-object formats pull in Ville's fix for the memcpy in drm_plane_init apply Ville's cleanup to zero out fb_cmd2 arg in drm_mode_addfb v5: add 'flags' field for interlaced support (from Ville) Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Acked-by: Alan Cox <alan@lxorguk.ukuu.org.uk> Reviewed-by: Rob Clark <rob.clark@linaro.org> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org> Signed-off-by: Dave Airlie <airlied@redhat.com>
