I'm not sure which trees the patches should go in via. The first two have already been applied by Sebastian (thanks). The binding and dts changes (patches 3-5) would make sense to go in via linux-mips with acks from the dt maintainers and the driver itself (patch 6) can go via linux-i2c. --- 2.46.1 Chris Packham (6): dt-bindings: reset: syscon-reboot: Add reg property power: reset: syscon-reboot: Accept reg property dt-bindings: mfd: Add Realtek RTL9300 switch peripherals mips: dts: realtek: Add syscon-reboot node mips: dts: realtek: Add I2C controllers i2c: Add driver for the RTL9300 I2C controller .../bindings/i2c/realtek,rtl9301-i2c.yaml | 69 +++ .../bindings/mfd/realtek,rtl9301-switch.yaml | 114 +++++ .../bindings/power/reset/syscon-reboot.yaml | 11 +- MAINTAINERS | 7 + .../cameo-rtl9302c-2x-rtl8224-2xge.dts | 2 +- arch/mips/boot/dts/realtek/rtl9302c.dtsi | 15 + arch/mips/boot/dts/realtek/rtl930x.dtsi | 29 ++ drivers/i2c/busses/Kconfig | 10 + drivers/i2c/busses/Makefile | 1 + drivers/i2c/busses/i2c-rtl9300.c | 425 ++++++++++++++++++ drivers/power/reset/syscon-reboot.c | 3 +- 11 files changed, 683 insertions(+), 3 deletions(-) create mode 100644 Documentation/devicetree/bindings/i2c/realtek,rtl9301-i2c.yaml create mode 100644 Documentation/devicetree/bindings/mfd/realtek,rtl9301-switch.yaml create mode 100644 arch/mips/boot/dts/realtek/rtl9302c.dtsi create mode 100644 drivers/i2c/busses/i2c-rtl9300.c
