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"
