From bd24924fea541c114c7761f4698f3fe29d7257e1 Mon Sep 17 00:00:00 2001
From: Dave Stevenson <dave.stevenson@raspberrypi.com>
Date: Thu, 9 Apr 2020 15:04:14 +0100
Subject: [PATCH] dtoverlays: Update CSI overlays to use i2c_csi_dsi

Update all overlays that were using i2c_vc for talking to CSI
source devices to use the new i2c_csi_dsi node via i2c_mux_pinctrl.
Remove the pins overrides as well.
