Subject: [PATCH v3 0/4] Add drivers for Sony Cronos control CPLD

Hello all,

This series adds a driver for the multi-function CPLD found on the Sony
Interactive Entertainment Cronos x86 server platform. It provides a
watchdog timer and an LED controller, both of which will depend on the
MFD parent driver implemented in this series. Device tree bindings are
also included.

Thanks,

Changes in v3:
  - Address reviewer concerns
  - Add LED and watchdog drivers to series
