2018-03-28drm/tinydrm: Make fb_dirty into a lower level hookVille Syrjälä3-1/+12
mipi_dbi_enable_flush() wants to call the fb->dirty() hook from the bowels of the .atomic_enable() hook. That prevents us from taking the plane mutex in fb->dirty() unless we also plumb down the acquire context. Instead it seems simpler to split the fb->dirty() into a tinydrm specific lower level hook that can be called from mipi_dbi_enable_flush() and from a generic higher level tinydrm_fb_dirty() helper. As we don't have a tinydrm specific vfuncs table we'll just stick it into tinydrm_device directly for now. v2: Deal with the fb->dirty() in tinydrm_display_pipe_update() as well (Noralf) Cc: "Noralf Trønnes" <[email protected]> Cc: David Lechner <[email protected]> Signed-off-by: Ville Syrjälä <[email protected]> Reviewed-by: Noralf Trønnes <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected] Reviewed-by: Noralf Trønnes <[email protected]> Tested-by: Noralf Trønnes <[email protected]>
