Merge tag 'regulator-v6.4' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator

Pull regulator updates from Mark Brown:
 "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.

  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"

+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.
