   - Use correct includes for GPIO handling; madera-core
   - Convert to GPIOD; twl6040
   - Remove unused platform data handling; twl6040
   - Device Tree changes; many
   - Remove unused drivers; dm355evm_msp, davinci_voicecodec, htc-i2cpld
   - Add support for modules; palmas
   - Enable COMPILE_TEST support; intel_soc_pmic*
   - Trivial: spelling / whitespace fixes; mc13xxx-spi
   - Replace old PM helpers with new ones; many
   - Convert deprecated mask_invert usage to unmask_base; many
   - Use devm_*() calls; qcom_rpm
   - MAINTAINER fix-ups
   - Make use of improved / replaced APIs; palmas, fsl-imx25-tsadc,
     stm32-lptimer, qcom_rpm, rohm-*

  Bug Fixes:
   - Add bounds / error checking; mt6360-core
   - No sleeping inside critical sections; axp20x
   - Fix missing dependencies; ROHM_BD957XMUF
   - Repair error paths; qcom-pm8008"
