regulator: wm831x-ldo: Fix max_uV for gp_ldo and aldo linear range settings
Fix the linear range settings in commit 5ff26a14c3331 "regulator: wm831x-ldo: Convert to use linear ranges". 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. Signed-off-by: Axel Lin <axel.lin@ingics.com> Signed-off-by: Mark Brown <broonie@linaro.org>
