   4 Subject: [PATCH] mfd: axp20x: Fix axp288 writable-ranges
   5
   6 Register AXP288_POWER_REASON is writable and needs to be written
   7 to reset the reset- / power-on-reason bits.
   8
   9 Add it to the axp288 writable-ranges so that the extcon-axp288
  10 driver can properly clear the reset- / power-on-reason bits.
