Merge tag 'mfd-next-4.20' of git://git.kernel.org/pub/scm/linux/kernel/git/lee/mfd
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"
