   - No not unnecessarily initialise variables; tps65910, tps65910
   - Reorganise and simplify driver data; omap-usb-tll
   - Move to SPDX license statement; tps68470
   - Probe ADCs via DT; axp20x
   - Use new GPIOD API; arizona-core
   - Constify things; axp20x
   - Reduce code-size (use MACROS, etc); axp20x, omap-usb-host
   - Add DT support/docs; motorola-cpcap
   - Remove VLAs; rave-sp
   - Use devm_* managed resources; cros_ec
   - Interrogate HW for firmware version; rave-sp
   - Provide ACPI support for ChromeOS Embedded-Controller

  Bug Fixes:
   - Reorder ordered (enum) device list; tps65218
   - Only accept valid data from the offset; rave-sp
   - Refrain from copying junk from failed SPI read; cros_ec_dev
   - Fix potential memory leaks; pcf50633-core
