Use a syscon-reboot node to represent this. Signed-off-by: Chris Packham Reviewed-by: Krzysztof Kozlowski --- Notes: Changes in v5: - Krzysztof did technically give a r-by on v4 but given the changes to the rest of the series I haven't included it. - Use reg instead of offset - Add a rtl9302c.dtsi for the specific chip which pulls in the generic rtl930x.dtsi and updates a few of the compatibles on the way through. - Update Cameo board to use rtl9302c.dtsi Changes in v4: - None Changes in v3: - None Changes in v2: - drop redundant status =3D "okay" .../dts/realtek/cameo-rtl9302c-2x-rtl8224-2xge.dts | 2 +- arch/mips/boot/dts/realtek/rtl9302c.dtsi | 7 +++++++ arch/mips/boot/dts/realtek/rtl930x.dtsi | 13 +++++++++++++ 3 files changed, 21 insertions(+), 1 deletion(-) create mode 100644 arch/mips/boot/dts/realtek/rtl9302c.dtsi diff --git a/arch/mips/boot/dts/realtek/cameo-rtl9302c-2x-rtl8224-2xge.dts = b/arch/mips/boot/dts/realtek/cameo-rtl9302c-2x-rtl8224-2xge.dts index 77d2566545f2..6789bf374044 100644 --- a/arch/mips/boot/dts/realtek/cameo-rtl9302c-2x-rtl8224-2xge.dts +++ b/arch/mips/boot/dts/realtek/cameo-rtl9302c-2x-rtl8224-2xge.dts @@ -1,7 +1,7 @@ // SPDX-License-Identifier: GPL-2.0-or-later /dts-v1/; =20 -#include "rtl930x.dtsi" +#include "rtl9302c.dtsi" =20 #include #include diff --git a/arch/mips/boot/dts/realtek/rtl9302c.dtsi b/arch/mips/boot/dts/= realtek/rtl9302c.dtsi new file mode 100644 index 000000000000..80d9f407e758 --- /dev/null +++ b/arch/mips/boot/dts/realtek/rtl9302c.dtsi @@ -0,0 +1,7 @@ +// SPDX-License-Identifier: GPL-2.0-or-later OR BSD-2-Clause + +#include "rtl930x.dtsi" + +&switch0 { + compatible =3D "realtek,rtl9302c-switch", "realtek,rtl9300-switch", "sysc= on", "simple-mfd"; +}; diff --git a/arch/mips/boot/dts/realtek/rtl930x.dtsi b/arch/mips/boot/dts/r= ealtek/rtl930x.dtsi index f271940f82be..89b8854596cd 100644 --- a/arch/mips/boot/dts/realtek/rtl930x.dtsi +++ b/arch/mips/boot/dts/realtek/rtl930x.dtsi @@ -29,6 +29,19 @@ lx_clk: clock-175mhz { #clock-cells =3D <0>; clock-frequency =3D <175000000>; }; + + switch0: switch@1b000000 { + compatible =3D "realtek,rtl9300-switch", "syscon", "simple-mfd"; + reg =3D <0x1b000000 0x10000>; + #address-cells =3D <1>; + #size-cells =3D <1>; + + reboot@c { + compatible =3D "syscon-reboot"; + reg =3D <0x0c 0x4>; + value =3D <0x01>; + }; + }; }; =20 &soc { --=20 2.46.2
