[PATCH v2] regulator: atc260x: Fix n_voltages and min_sel for pickable linear ranges

From: Axel Lin
Date: Fri May 28 2021 - 19:02:03 EST


The .n_voltages was missed for pickable linear ranges, fix it.
The min_sel for each pickable range should be starting from 0.
Also fix atc260x_ldo_voltage_range_sel setting (bit 5 - LDO<N>_VOL_SEL
in datasheet).

Fixes: 3b15ccac161a ("regulator: Add regulator driver for ATC260x PMICs")
