arm64: dts: actions: s900-bubblegum-96: Enable I2C1 and I2C2 (07b308ee) · Commits · 戴 / test

Add pinctrl definitions for Actions Semiconductor S900 I2C controllers. Pinctrl definitions are only available for I2C0, I2C1, and I2C2. Enable I2C1 and I2C2 exposed on the low speed expansion connector in Bubblegum-96 board. Signed-off-by:
