- Add support for Lakefield PCH to Intel LPSS PCI
- Remove Device Support
- Remove support for ROHM BD70528 Power Management IC
- New Functionality
- Add support for SMBus and I2C mode to Dialog DA9062/61 PMIC
- Enable I2C4 on Microsoft Surface Go & Go 2
- Fix-ups
- Device Tree changes (inc. YAML conversion); maxim,max77686,
rohm,bd9571mwv, syscon, brcm,twd, google,cros-ec
- Use __maybe_unused instead of #ifery; atmel-flexcom
