Pull MFD updates from Lee Jones:
 "New Drivers:
   - ROHM BD96801 Power Management IC
   - Cirrus Logic CS40L50 Haptic Driver with Waveform Memory
   - Marvell 88PM886 Power Management IC

  New Device Support:
   - Keyboard Backlight to ChromeOS Embedded Controller
   - LEDs to ChromeOS Embedded Controller
   - Charge Control to ChromeOS Embedded Controller
   - HW Monitoring Service to ChromeOS Embedded Controller
   - AUXADCs to MediaTek MT635{7,8,9} Power Management ICs

  New Functionality:
   - Allow Syscon consumers to supply their own Regmaps on registration

  Fix-ups:
   - Constify/staticise applicable data structures
   - Remove superfluous/duplicated/unused sections
   - Device Tree binding adaptions/conversions/creation
   - Trivial; spelling, whitespace, coding-style adaptions
   - Utilise centrally provided helpers and macros to aid
     simplicity/duplication
   - Drop i2c_device_id::driver_data where the value is unused
   - Replace ACPI/DT firmware helpers with agnostic variants
   - Move over to GPIOD (descriptor-based) APIs
   - Annotate a bunch of __counted_by() cases
   - Straighten out some includes

  Bug Fixes:
   - Ensure potentially asserted recent lines are deasserted during
     initialisation
   - Avoid "<module>.ko is added to multiple modules" warnings
   - Supply a bunch of MODULE_DESCRIPTIONs to silence modpost warnings
   - Fix Wvoid-pointer-to-enum-cast warnings"
