From 92bc66bfce99cd7d5b66cb1086812a32300c5705 Mon Sep 17 00:00:00 2001 From: Eugeniu Rosca Date: Sun, 12 Aug 2018 15:31:47 +0200 Subject: [PATCH] arm64: dts: renesas: r8a77965: Add CAN{0,1} placeholder nodes According to R-Car Gen3 HW manual rev1.00, R-Car M3-N has two CAN interfaces, similar to H3, M3-W and other SoCs from the same family. Add CAN placeholder nodes to avoid below DTC errors: Error: arch/arm64/boot/dts/renesas/ulcb-kf.dtsi:19.1-6 Label or path can0 not found Error: arch/arm64/boot/dts/renesas/ulcb-kf.dtsi:25.1-6 Label or path can1 not found These errors occur *after* the addition of r8a77965-m3nulcb-kf.dts. Fix them beforehand. CAN support is inspired from below commits: - v4.7 commit 308b7e4ba62e ("arm64: dts: r8a7795: Add CAN support") - v4.11 commit 909c16252415 ("arm64: dts: r8a7796: Add CAN support") - v4.12 commit bec0948e810f ("arm64: dts: r8a7796: Add reset control properties") Signed-off-by: Eugeniu Rosca Reviewed-by: Kieran Bingham [simon: make placeholder minimal by only including reg property] Signed-off-by: Simon Horman --- arch/arm64/boot/dts/renesas/r8a77965.dtsi | 10 ++++++++++ 1 file changed, 10 insertions(+) diff --git a/arch/arm64/boot/dts/renesas/r8a77965.dtsi b/arch/arm64/boot/dts/renesas/r8a77965.dtsi index 7a75c351edd2..e7128fb65e33 100644 --- a/arch/arm64/boot/dts/renesas/r8a77965.dtsi +++ b/arch/arm64/boot/dts/renesas/r8a77965.dtsi @@ -862,6 +862,16 @@ status = "disabled"; }; + can0: can@e6c30000 { + reg = <0 0xe6c30000 0 0x1000>; + /* placeholder */ + }; + + can1: can@e6c38000 { + reg = <0 0xe6c38000 0 0x1000>; + /* placeholder */ + }; + pwm0: pwm@e6e30000 { compatible = "renesas,pwm-r8a77965", "renesas,pwm-rcar"; reg = <0 0xe6e30000 0 8>; -- 2.30.2
