regulator: twl-regulator: fix n_voltages for twl6030 variable LDOs
The n_voltages initializer for the TWL6030_ADJUSTABLE_LDO macro is off by one, causing the the highest supported voltage to be unreachable. Setting the machine constraints to only allow the highest voltage causes errors: machine_constraints_voltage: VAUX3_6030: unsupportable voltage constraints twl_reg twl_reg.39: can't register VAUX3_6030, -22 twl_reg: probe of twl_reg.39 failed with error -22 This patch fixes the off by one error. Tested by setting VAUX3_6030 to 3.3V. Signed-off-by: Colin Cross <ccross@android.com> Acked-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Liam Girdwood <lrg@slimlogic.co.uk>
