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"
