The board level reset on systems using the RTL9302 can be driven via the switch. Use a syscon-reboot node to represent this. Signed-off-by: Chris Packham <chris.packham@alliedtelesis.co.nz> --- Notes: Changes in v8: - None Changes in v7: - None Changes in v6: - Drop wildcard compatible 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 = "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
