Merge tag 'mfd-next-5.8' of git://git.kernel.org/pub/scm/linux/kernel/git/lee/mfd
Pull MFD updates from Lee Jones:
"Core Frameworks:
- Constify 'properties' attribute in core header file
New Drivers:
- Add support for Gateworks System Controller
- Add support for MediaTek MT6358 PMIC
- Add support for Mediatek MT6360 PMIC
- Add support for Monolithic Power Systems MP2629 ADC and Battery charger
Fix-ups:
- Use new I2C API in htc-i2cpld
- Remove superfluous code in sprd-sc27xx-spi
- Improve error handling in stm32-timers
- Device Tree additions/fixes in mt6397
- Defer probe betterment in wm8994-core
- Improve module handling in wm8994-core
- Staticify in stpmic1
- Trivial (spelling, formatting) in tqmx86
Bug Fixes:
- Fix incorrect register/PCI IDs in intel-lpss-pci
- Fix unbalanced Regulator API calls in wm8994-core
- Fix double free() in wcd934x
- Remove IRQ domain on failure in stmfx
- Reset chip on resume in stmfx
- Disable/enable IRQs on suspend/resume in stmfx
- Do not use bulk writes on H/W which does not support them in max77620"
