The PMIC is also known as AXP819 in vendor pmu code For DCDC6, 8, 9, the underlying hardware support more than two levels voltage step tuning, but for now only first two levels are implemented in this driver, hence highest voltage will be limited at seccond level. It actual meets board requirement in current design, and we've verified it in Radxa Cubie A7A board. Following are detail explanation of voltage tuning stpes for those DCDCs: DCDC | voltage range | units | steps | implemented 6 | 0.5 - 1.2 | 10 mV | 71 | Y . | 1.22 - 1.54 | 20 mV | 17 | Y . | 1.8 - 2.4 | 20 mV | 31 | N . | 2.44 - 2.76 | 40 mV | 9 | N -------------------------------------------------- 8/9 | 0.5 - 1.2 | 10 mV | 71 | Y . | 1.22 - 1.84 | 20 mV | 32 | Y . | 1.9 - 3.4 | 100mV | 16 | N Signed-off-by: Yixun Lan <dlan@gentoo.org> Reviewed-by: Andre Przywara <andre.przywara@arm.com>
