For wm831x_gp_ldo: We have below equations for list voltage before converting to linear ranges: sel <= 0xe: volt = 0.9-1.6V in 50mV steps sel <= 0x1f: volt = 1.7-3.3V in 100mV steps max_uV for the first linear range should be 1600000 rather than 1650000. Fix it. For wm831x_aldo: We have below equations for list voltage before converting to linear ranges: sel <= 0xc: volt = 1-1.6V in 50mV steps sel <= 0x1f volt = 1.7-3.5V in 100mV steps max_uV for the first linear range should be 1600000 rather than 1650000. Fix it.
