regulator: Updates for v6.4

Browse Source 
A fairly quiet release, there were some cleanup and a couple of new
 devices but the biggest change was converting most of the drivers to use
 asynchronous probe.  This allows us to ramp up multiple regulators in
 parallel during boot which can have a noticable impact on modern
 systems.
 
  - Update of drivers to PROBE_PREFER_ASYNCHRONOUS to mitigate issues
    with ramp times slowing down boots.
  - Convert to void remove callbacks.
  - Support for voltage monitoring on DA9063
  - Support for Qualcomm PMC8180 and PMM8654au, Richtek RT4803 and
    RT5739, Rockchip RK860x,

  Summary:

   - Update of drivers to PROBE_PREFER_ASYNCHRONOUS to mitigate issues
     with ramp times slowing down boots.

   - Convert to void remove callbacks.

   - Support for voltage monitoring on DA9063

   - Support for Qualcomm PMC8180 and PMM8654au, Richtek RT4803 and
     RT5739, Rockchip RK860x"

For device-tree bindings of other sub-modules refer to the binding documents

Using regulator-{uv,ov}-{warn,error,protection}-microvolt requires special
handling: First, when GP_FB2 is used, it must be ensured that there is no
moment where all voltage monitors are disabled. Next, as da9063 only supports
UV *and* OV monitoring, both must be set to the same severity and value
(0: disable, 1: enable).

maintainers:

description: |
RT4803 is a boost regulator that's designed to provide the minimum output
voltage, even if the input voltage is lower than the required voltage. It
supports boost and auto bypass mode that depends on the difference between the
input and output voltage. If the input is lower than the output, mode will
transform to boost mode. Otherwise, turn on bypass switch to enter bypass mode.
