The currently specified pin groups and function names prevented PCF and DU interfaces from being correctly configured: sh-pfc e6060000.pin-controller: function 'du' not supported sh-pfc e6060000.pin-controller: invalid function du in map table sh-pfc e6060000.pin-controller: function 'du' not supported sh-pfc e6060000.pin-controller: invalid function du in map table sh-pfc e6060000.pin-controller: function 'du' not supported sh-pfc e6060000.pin-controller: invalid function du in map table sh-pfc e6060000.pin-controller: function 'du' not supported sh-pfc e6060000.pin-controller: invalid function du in map table rcar-du: probe of feb00000.display failed with error -22 Signed-off-by: Jacopo Mondi --- Patch applied against Simon Horman's renesas/master branch. The PCF pin groups and function renaming was introduced by commit 56ed4bb9 and DTS for ALT board has never been update accordingly. Tested displaying frames on VGA interface: the rcar-du driver loads correctly. arch/arm/boot/dts/r8a7794-alt.dts | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/arch/arm/boot/dts/r8a7794-alt.dts b/arch/arm/boot/dts/r8a7794-alt.dts index 8d1b35a..9d65fb3 100644 --- a/arch/arm/boot/dts/r8a7794-alt.dts +++ b/arch/arm/boot/dts/r8a7794-alt.dts @@ -165,8 +165,8 @@ pinctrl-names = "default"; du_pins: du { - groups = "du1_rgb666", "du1_sync", "du1_disp", "du1_dotclkout0"; - function = "du"; + groups = "du1_rgb666", "du1_sync", "du1_disp", "du1_clk0_out"; + function = "du1"; }; scif2_pins: scif2 {
