   - Add support for STMPE, many
   - Add support for USB in X-Powers AXP22X

  Core Frameworks:
   - New Base API to traverse devices and their children in reverse order

  Bug Fixes:
   - Fix race between runtime-suspend and IRQs
   - Obtain platform data form more reliable source

  Fix-ups:
   - Constifying things
   - Variable signage changes
   - Kconfig depends|selects changes
   - Make use of BIT() macro
   - Do not supply .owner attribute in *_driver structures
   - MAINTAINERS entries
