Add support for the R-Car V3M (R8A77970) SoC to the R-Car DU driver. Signed-off-by: Sergei Shtylyov <redacted> --- Changes in version 2: - removed the 'model' and 'dpll_ch' field initializers; - fixed up the DU port numbers; - split the DU bindings and the LVDS driver updates into a separate patches; - removed the check before the DPTSR write (to be done in a separate patch). drivers/gpu/drm/rcar-du/rcar_du_drv.c | 21 +++++++++++++++++++++ 1 file changed, 21 insertions(+) Index: linux/drivers/gpu/drm/rcar-du/rcar_du_drv.c ===================================================================
