This series adds the device tree parts needed to use them on H6, starting with the Tanix TX6 and TX6 mini TV boxes, whose only Ethernet port goes through the PHY in the AC200 co-packaged with the H6. Patch 1 describes the AC200 in the H6 dtsi: the I2C3 controller with the AC200 on it, a pwm-clock that provides its 24 MHz reference clock from PWM1, the RMII pins and the EPHY calibration value in the SID. Everything stays disabled. Patch 2 enables Ethernet on the Tanix boards. Tested on a Tanix TX6: 100 Mbit/s full duplex, about 11 MB/s in each direction, and the link comes up both after cold boots with no Ethernet initialisation in U-Boot and after U-Boot has used it. The TX6 mini shares the same dtsi and was not tested separately. The arm64 defconfig does not enable CONFIG_MFD_AC200 and CONFIG_XPOWERS_ACX00_PHY yet; I can send a separate patch for that.
