Pull MFD updates from Lee Jones:
"New Drivers:
- Add new driver for MAXIM MAX77620/MAX20024 PMIC
- Add new driver for Hisilicon HI665X PMIC
New Device Support:
- Add support for AXP809 in axp20x-rsb
- Add support for Power Supply in axp20x
New core features:
- devm_mfd_* managed resources
Fix-ups:
- Remove unused code (da9063-irq, wm8400-core, tps6105x,
smsc-ece1099, twl4030-power)
- Improve clean-up in error path (intel_quark_i2c_gpio)
- Explicitly include headers (syscon.h)
- Allow building as modules (max77693)
- Use IS_ENABLED() instead of rolling your own (dm355evm_msp,
wm8400-core)
- DT adaptions (axp20x, hi655x, arizona, max77620)
- Remove CLK_IS_ROOT flag (intel-lpss, intel_quark)
- Move to gpiochip API (asic3, dm355evm_msp, htc-egpio, htc-i2cpld,
sm501, tc6393xb, tps65010, ucb1x00, vexpress)
- Make use of devm_mfd_* calls (act8945a, as3711, atmel-hlcdc,
bcm590xx, hi6421-pmic-core, lp3943, menf21bmc, mt6397, rdc321x,
rk808, rn5t618, rt5033, sky81452, stw481x, tps6507x, tps65217,
wm8400)
Bug Fixes"
- Fix ACPI child matching (mfd-core)
- Fix start-up ordering issues (mt6397-core, arizona-core)
- Fix forgotten register state on resume (intel-lpss)
- Fix Clock related issues (twl6040)
- Fix scheduling whilst atomic (omap-usb-tll)
- Kconfig changes (vexpress)"
