Merge tag 'mfd-next-5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/lee/mfd
Pull MFD updates from Lee Jones:
"New Device Support
- Add support for {Power,Home} Keys to MediaTek MT6359
- Add support for SC2730 to Spreadtrum SPRD SC27XX SPI
- Add support for additional Alder Lake-P I2C Controllers to Intel
LPSS PCI
Fix-ups:
- Convert GPIO to GPIOD (hi655x-pmic)
- Only register devices that exist (cros_ec_dev)
- Remove unused code (syscon, reg-mux)
- Rework .remove() API to return void (twl-core, rt4831)
- Trivial - whitespace, spelling, coding style (tps65218,
sprd-sc27xx-spi, google,cros-ec)
- DT binding changes (samsung,exynos5433-lpass, rockchip,rk805,
rockchip,rk808, rockchip,rk809, rockchip,rk817, rockchip,rk818,
wlf,arizona)
Bug Fixes:
- Fix error handling bugs (ipaq-micro, davinci_voicecodec)"
