* regulator: Set PROBE_PREFER_ASYNCHRONOUS for drivers between 4.19 and 5.4Douglas Anderson2023-03-201-0/+1
| | | | | | | | | | This follows on the change ("regulator: Set PROBE_PREFER_ASYNCHRONOUS for drivers that existed in 4.14") but changes regulators didn't exist in Linux 4.19 but did exist in Linux 5.4.

* regulator: lochnagar: Add additional VDDCORE rangeCharles Keepax2020-09-071-0/+1
| | | | | | | | | | | | In the case of an unrecognised mini-card the Lochnagar will not initialise the VDDCORE voltage register leading to a value outside of the current range. Add an additional range to cover these values, initially this wasn't done since they are duplicates of the existing minimum value.

* regulator: lochnagar: Add on_off_delay for VDDCORECharles Keepax2019-10-011-0/+1
| | | | | | | | | | The VDDCORE regulator takes a good length of time to discharge down, so add an on_off_delay to ensure DCVDD is removed before it is powered on again.

| * regulator: lochnagar: Fix n_voltages setting for VDDCOREAxel Lin2019-02-071-1/+1
| | | | | | | | | | | | | | | | | | | | With current n_voltages setting, regulator_list_voltage will return -EINVAL when selector >=57. The highest selector is 0x41, so the n_voltages should be 0x41+1, i.e. 66.

* regulator: lochnagar: Add support for the Cirrus Logic LochnagarCharles Keepax2018-10-121-0/+255
Lochnagar is an evaluation and development board for Cirrus Logic Smart CODEC and Amp devices. It allows the connection of most Cirrus Logic devices on mini-cards, as well as allowing connection of various application processor systems to provide a full evaluation platform. This driver supports the board controller chip on the Lochnagar board. The Lochnagar board provides power supplies for the attached CODEC/Amp device. Currently this driver supports the microphone supplies and the digital core voltage for the attached device. There are some additional supplies that will be added in time but these supplies are sufficient for most systems/use-cases.
