Pull MFD updates from Lee Jones:
"Core Frameworks:
- Set 'struct device' fwnode when registering a new device
New Drivers:
- Add support for ROHM BD70528 PMIC
New Device Support:
- Add support for LP87561 4-Phase Regulator to TI LP87565 PMIC
- Add support for RK809 and RK817 to Rockchip RK808
- Add support for Lid Angle to ChromeOS core
- Add support for CS47L15 CODEC to Madera core
- Add support for CS47L92 CODEC to Madera core
- Add support for ChromeOS (legacy) Accelerometers in ChromeOS core
- Add support for Add Intel Elkhart Lake PCH to Intel LPSS
New Functionality:
- Provide regulator supply information when registering; madera-core
- Additional Device Tree support; lp87565, madera, cros-ec, rohm,bd71837-pmic
- Allow over-riding power button press via Device Tree; rohm-bd718x7
- Differentiate between running processors; cros_ec_dev
Fix-ups:
- Big header file update; cros_ec_commands.h
- Split header per-subsystem; rohm-bd718x7
- Remove superfluous code; menelaus, cs5535-mfd, cs47lXX-tables
- Trivial; sorting, coding style; intel-lpss-pci
- Only remove Power Off functionality if set locally; rk808
- Make use for Power Off Prepare(); rk808
- Fix spelling mistake in header guards; stmfx
- Properly free IDA resources
- SPDX fixups; cs47lXX-tables, madera
- Error path fixups; hi655x-pmic
Bug Fixes:
- Add missing break in case() statement
- Repair undefined behaviour when not initialising variables; arizona-core, madera-core
- Fix reference to Device Tree documentation; madera"
