From 46fbde5380a7a1707e19ac46842cb9ce526c5216 Mon Sep 17 00:00:00 2001
From: Dave Stevenson <dave.stevenson@raspberrypi.com>

Subject: [PATCH] ARM: dts: bcm2711-cm4s Correct i2c0mux to use 0/1 and
28/29 & 2 regulators
CM4S follows CM1/3, so based on the documentation cameras/displays
connect to 0/1 and 28/29, not 0/1 and 44/45.
Likewise the camera regulator controls are independent as on CM1/3.
