Document the "op_mode" properties parsed from DTS by s2mps11 driver. S2MPS11/S2MPS14 regulators support different modes of operation: - Always off; - On/Off controlled by pin/GPIO (PWREN/LDOEN/EMMCEN); - Always on; This is very similar to S5M8767 regulator driver which also supports opmodes (although S5M8767 have also low-power mode).
