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)"

-Regulators: All the regulators of RK8XX to be instantiated shall be
-listed in a child node named 'regulators'. Each regulator is represented
-by a child node of the 'regulators' node.
-
-	regulator-name {
-		/* standard regulator bindings here */
-	};
-
-Following regulators of the RK805 PMIC regulators are supported. Note that
-the 'n' in regulator name, as in DCDC_REGn or LDOn, represents the DCDC or LDO
-number as described in RK805 datasheet.
-
-	- DCDC_REGn
-		- valid values for n are 1 to 4.
-	- LDO_REGn
-		- valid values for n are 1 to 3
-
-Following regulators of the RK808 PMIC block are supported. Note that
-the 'n' in regulator name, as in DCDC_REGn or LDOn, represents the DCDC or LDO
-number as described in RK808 datasheet.
-
-	- DCDC_REGn
-		- valid values for n are 1 to 4.
-	- LDO_REGn
-		- valid values for n are 1 to 8.
-	- SWITCH_REGn
-		- valid values for n are 1 to 2
-
-Following regulators of the RK809 and RK817 PMIC blocks are supported. Note that
-the 'n' in regulator name, as in DCDC_REGn or LDOn, represents the DCDC or LDO
-number as described in RK809 and RK817 datasheets.

-
-It is necessary to configure three pins for both the RK809 and RK817, the three
-pins are "gpio_ts" "gpio_gt" "gpio_slp".
-	The gpio_gt and gpio_ts pins support the gpio function.
-	The gpio_slp pin is for controlling the pmic states, as below:
-		- reset
-		- power down
-		- sleep
-
-Standard regulator bindings are used inside regulator subnodes. Check
