Merge tag 'mfd-next-4.21' of git://git.kernel.org/pub/scm/linux/kernel/git/lee/mfd

Pull MFD updates from Lee Jones:
 "New Device Support
   - Add support for Power Supply to AXP813
   - Add support for GPIO, ADC, AC and Battery Power Supply to AXP803
   - Add support for UART to Exynos LPASS

  Fix-ups:
   - Use supplied MACROS; ti_am335x_tscadc
   - Trivial spelling/whitespace/alignment; tmio, axp20x, rave-sp
   - Regmap changes; bd9571mwv, wm5110-tables
   - Kconfig dependencies; MFD_AT91_USART
   - Supply shared data for child-devices; madera-core
   - Use new of_node_name_eq() API call; max77620, stmpe
   - Use managed resources (devm_*); tps65218
   - Comment descriptions; ingenic-tcu
   - Coding style; madera-core

  Bug Fixes:
   - Fix section mismatches; twl-core, db8500-prcmu
   - Correct error path related issues; mt6397-core, ab8500-core, mc13xxx-core
   - IRQ related fixes; tps6586x
   - Ensure proper initialisation sequence; qcom_rpm
   - Repair potential memory leak; cros_ec_dev"
