arm64: dts: renesas: r8a77965: Add CAN{0,1} placeholder nodes

erosca · horms · commit 92bc66bfce99 · 2018-09-13T09:47:15.000+02:00
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 308b7e4 ("arm64: dts: r8a7795: Add CAN support") - v4.11 commit 909c162 ("arm64: dts: r8a7796: Add CAN support") - v4.12 commit bec0948 ("arm64: dts: r8a7796: Add reset control properties") Signed-off-by: Eugeniu Rosca <erosca@de.adit-jv.com> Reviewed-by: Kieran Bingham <kieran.bingham+renesas@ideasonboard.com> [simon: make placeholder minimal by only including reg property] Signed-off-by: Simon Horman <horms+renesas@verge.net.au>
