Merge tag 'regulator-v5.18' of git://git.kernel.org/pub/scm/linux/ker…
…nel/git/broonie/regulator
Pull regulator updates from Mark Brown:
"Quite a quiet release for the regulator API, mainly a few new drivers
plus a lot of fixes for the Raspberry Pi panel driver.
There's also a SPI commit in here which I managed to apply to the
wrong tree and then didn't notice until there were too many commits on
top of it, sorry about that.
- Make it easier to use the virtual consumer test driver with DT
systems.
- Substantial overhaul providing various fixes and robustness
improvements for the Raspberry Pi panel driver.
- Support for Qualcomm PMX65 and SDX65, Richtek RT5190A, and Texas
Instruments TPS62864x"

| synchronous buck converters, 1 LDO, I2C control interface and peripherial | ||
| logical control. | ||
| It also supports mute AC OFF depop sound and quick setting storage while | ||

| richtek,mute-enable: | ||
| description: | | ||
| The mute function uses 'mutein', 'muteout', and 'vdet' pins as the control | ||
| signal. When enabled, The normal behavior is to bypass the 'mutein' signal | ||
| 'muteout'. But if the power source removal is detected from 'vdet', | ||
| whatever the 'mutein' signal is, it will pull down the 'muteout' to force | ||
| speakers mute. this function is commonly used to prevent the speaker pop | ||
| noise during AC power turned off in the modern TV system design. | ||
