2022-11-22regulator: twl6030: fix get status of twl6032 regulatorsAndreas Kemnade1-4/+11
Status is reported as always off in the 6032 case. Status reporting now matches the logic in the setters. Once of the differences to the 6030 is that there are no groups, therefore the state needs to be read out in the lower bits.

2022-11-22regulator: twl6030: re-add TWL6032_SUBCLASSAndreas Kemnade1-0/+2
In former times, info->feature was populated via the parent driver by pdata/regulator_init_data->driver_data for all regulators when USB_PRODUCT_ID_LSB indicates a TWL6032. Today, the information is not set, so re-add it at the regulator definitions.

2019-08-09regulator: twl6030: workaround the VMMC reset behaviorGregory CLEMENT1-1/+14
During reset the VMMC regulator doesn't reach 0V and only drops to 1.8V, furthermore the pulse width is under 200us whereas the SD specification expect 1ms. The WR_S bit allows the TWL6030 to no reset at all the VMMC during warm reset and keep the current voltage. Thanks to this workaround the SD card doesn't reach a undefined reset stage. Actually this behavior is available for all the LDO regulator, so the driver will also allow to use it with any of these regulator.

<= 1350000 It has been pointed out to me that the range for vsel = 58 is actually dead code as this is covered by an earlier check for (min_uV >= 700000) && (min_uV <= 1420000) so remove that check completely.

The range min_uV > 1350000 && min_uV <= 150000 is never reachable because of a typo in the previous range check and hence vsel = 59 is never reached.

In order to not break existing users, we keep using the same CONFIG symbol. This makes it easier to add support for TWL6032 and refactor mfd/twl-core. Checkpatch warnings are inherited from twl-regulator.c and will be addressed in a subsequent patch.
