Add a link from the Clock Pulse Generator node to the Reset Controller node, so the CPG can read the Mode Monitoring Register (MODEMR) to obtain the MD pin values.x Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> --- arch/arm/boot/dts/r8a7790.dtsi | 1 + 1 file changed, 1 insertion(+)diff --git a/arch/arm/boot/dts/r8a7790.dtsi b/arch/arm/boot/dts/r8a7790.dtsi index 08067ae177643b8f..4ee5523fc3e13e12 100644 --- a/arch/arm/boot/dts/r8a7790.dtsi +++ b/arch/arm/boot/dts/r8a7790.dtsi@@ -1115,6 +1115,7 @@ "lb", "qspi", "sdh", "sd0", "sd1", "z", "rcan", "adsp"; #power-domain-cells = <0>; + renesas,modemr = <&rst 0x60>;
I have mixed feelings about this as I don't think it really describes the hardware. Wouldn't it make sense to instead add a standard kernel API to retrieve the boot mode value ? It seems to be a pretty common feature of SoCs across all vendors.
