-From 77d7427bed21c92d1c10e0cc9beabb5ce9bb6c0b Mon Sep 17 00:00:00 2001
-From: Dave Stevenson <dave.stevenson@raspberrypi.com>
-Date: Thu, 9 Apr 2020 12:46:13 +0100
-Subject: [PATCH] dt: Implement an I2C pinctrl mux for BSC0.
-
-BSC0 serves either the HAT EEPROM pins on the 40pin connector,
-or the display and camera on a board specific pairing of either
-GPIO 28&29, or 44&45.
-
-Use I2C_MUX_PINCTRL to allow exposing both pairs of pins as I2C
-busses.
-
-Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>
