+- samsung,s2mps11-acokb-ground: Indicates that ACOKB pin of S2MPS11 PMIC is
+  connected to the ground so the PMIC must manually set PWRHOLD bit in CTRL1
+  register to turn off the power. Usually the ACOKB is pulled up to VBATT so
+  when PWRHOLD pin goes low, the rising ACOKB will trigger power off.
