Pull MFD updates from Lee Jones:
 "New Drivers
   - Add support for USART SPI to AT91*

  New Functionality
   - Add support for Audio CODECs to motorola-cpcap

  Fix-ups
   - DT documentation fix-ups; atmel-usart
   - Staticise functions/structs; spi-at91-usart, arizona-core
   - Constify; ti-lmu
   - Fix memory leaks; menelaus
   - Change device 'wake-up' status; ti_am335x_tscadc, max8997
   - Power Management (suspend/resume) semantic changes; ti_am335x_adc, cros_ec, max8997
   - SPDX churn; sec-core (+ headers), max* (+ headers), intel* (+ headers),
   - Trivial (whitespace, email addresses, alphabetisise); Kconfig, adp5520, intel_soc_pmic_*
   - Build as module; sec-irq
   - Use new %pOFn printk format for device_node.name; max77620
   - Remove unused code; madera
   - Use generic MACROs; intel_msic, intel_soc_pmic_crc
   - Move to GPIOD; ti-lmu
   - Use managed resources; ti-lmu

  Bug Fixes
   - Add missing headers; at91-usart
   - Prevent device from entering low-power mode; arizona-core
   - Poll for BOOT_DONE to avoid still-booting NACK; madera-core
   - Prevent ADC read from shutting down device; mc13xxx-core"
