-Broadcom BCM2835 I2C controller
-
-Required properties:
-- compatible : Should be one of:
- "brcm,bcm2711-i2c"
- "brcm,bcm2835-i2c"
-- reg: Should contain register location and length.
-- interrupts: Should contain interrupt.
-- clocks : The clock feeding the I2C controller.
-
-Recommended properties:
-- clock-frequency : desired I2C bus clock frequency in Hz.

-Example:
-
-i2c@7e205000 {
- compatible = "brcm,bcm2835-i2c";
- reg = <0x7e205000 0x1000>;
- interrupts = <2 21>;
- clocks = <&clk_i2c>;
- clock-frequency = <100000>;
