   - 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"
