This patch adds pinmux and spi1 nodes to the carrier board dtsi file and drops deleting pinctl* properties from DTS file. RSPI1 interface is tested by setting the macro SW_RSPI_CAN to 0. Signed-off-by: Biju Das Reviewed-by: Lad Prabhakar Reviewed-by: Geert Uytterhoeven --- v2->v3: * Removed redundant spi1 node, as it is already enabled in common. v1->v2: * Sorted the node alphabetically * Delete/disable pinctrl/spi node, when SW_RSPI_CAN macro is set to 1. This change is done in common file, so that both single core and dual core RZ/G2LC SMARC EVK can reuse the same. --- arch/arm64/boot/dts/renesas/r9a07g044c2-smarc.dts | 6 ------ arch/arm64/boot/dts/renesas/rzg2lc-smarc-pinfunction.dtsi | 7 +++++++ arch/arm64/boot/dts/renesas/rzg2lc-smarc.dtsi | 8 ++++++++ 3 files changed, 15 insertions(+), 6 deletions(-) diff --git a/arch/arm64/boot/dts/renesas/r9a07g044c2-smarc.dts b/arch/arm64/boot/dts/renesas/r9a07g044c2-smarc.dts index 74a2f2bade10..fc34058002e2 100644 --- a/arch/arm64/boot/dts/renesas/r9a07g044c2-smarc.dts +++ b/arch/arm64/boot/dts/renesas/r9a07g044c2-smarc.dts @@ -13,9 +13,3 @@ model = "Renesas SMARC EVK based on r9a07g044c2"; compatible = "renesas,smarc-evk", "renesas,r9a07g044c2", "renesas,r9a07g044"; }; - -&spi1 { - /delete-property/ pinctrl-0; - /delete-property/ pinctrl-names; - status = "disabled"; -}; diff --git a/arch/arm64/boot/dts/renesas/rzg2lc-smarc-pinfunction.dtsi b/arch/arm64/boot/dts/renesas/rzg2lc-smarc-pinfunction.dtsi index d275a55333e3..a78a8def363e 100644 --- a/arch/arm64/boot/dts/renesas/rzg2lc-smarc-pinfunction.dtsi +++ b/arch/arm64/boot/dts/renesas/rzg2lc-smarc-pinfunction.dtsi @@ -106,6 +106,13 @@ input-enable; }; + spi1_pins: spi1 { + pinmux = , /* CK */ + , /* MOSI */ + , /* MISO */ + ; /* SSL */ + }; + ssi0_pins: ssi0 { pinmux = , /* BCK */ , /* RCK */ diff --git a/arch/arm64/boot/dts/renesas/rzg2lc-smarc.dtsi b/arch/arm64/boot/dts/renesas/rzg2lc-smarc.dtsi index 74ad1ede3d0b..9ec8c503b0a3 100644 --- a/arch/arm64/boot/dts/renesas/rzg2lc-smarc.dtsi +++ b/arch/arm64/boot/dts/renesas/rzg2lc-smarc.dtsi @@ -158,3 +158,11 @@ status = "okay"; }; #endif + +#if (SW_RSPI_CAN) +&spi1 { + /delete-property/ pinctrl-0; + /delete-property/ pinctrl-names; + status = "disabled"; +}; +#endif
