   4 Subject: [PATCH] overlays: Make the i2c-gpio overlay safe again
   5
   6 Like many overlays, the i2c-gpio overlay goes to efforts to avoid
   7 generating warnings about #address-cells and #size-cells not
   8 being defined, which it does by defining them. Unfortunately this
   9 is fatal if they don't match what the system requires, and the
  10 recent switch to #size-cells = 2 on 2711 made i2c-gpio very
  11 dangerous.
  12
  13 In the absence of the knowledge of a clean way to fix this, just delete
  14 the declarations and suffer the warnings.
