   4 Subject: [PATCH] ARM: dts: bcm2711-cm4s Correct i2c0mux to use 0/1 and
   5  28/29 & 2 regulators
   6
   7 CM4S follows CM1/3, so based on the documentation cameras/displays
   8 connect to 0/1 and 28/29, not 0/1 and 44/45.
   9
  10 Likewise the camera regulator controls are independent as on CM1/3.
