This commit introduces a port of the Linux kernel's driver for the
Mediatek's MT7621 I2C controller.
The port was undertaken as the existing driver intended for Mediatek
I2C controllers (mtk_i2c.c) is not compatible with the MT7621.
To use the driver:
1. Ensure that the mode of the i2c pin group is
configured for "i2c" rather than "gpio".
2. Delete the existing (bitbanged) i2c node from
arch/mips/dts/mt7621.dtsi, or specify:
/delete-node/ &i2c;
3. Declare:
i2c: i2c@1e000900 {
compatible = "mediatek,mt7621-i2c";
reg = <0x1e000900 0x100>;
clocks = <&clk50m>;
clock-names = "sys_clock";
resets = <&rstctrl RST_I2C>;
reset-names = "i2c_reset";
pinctrl-names = "default";
pinctrl-0 = <&i2c_pins>;
#address-cells = <1>;
#size-cells = <0>;
status = "okay";
};
