-Subject: [PATCH] dt: Update all mainline bcm283x dt files for i2c0
- pinctrl mux
-
-BSC0 (aka i2c0) can me muxed via pinctrl to GPIOs 0&1, 28&29, or
-44&45. These have different uses based on the platform (40pin header,
-and CSI/DSI connectors), so add a pinctrl I2C mux between the
-different options.
