- Stefan updates the BCM2835 SoC driver with downstream properties and
  uses that to implement a reboot notifier to tell the VC4 firmware when
  Linux on the ARM CPU is rebooting

- Eric adds a proper power domain driver for the BCM283x SoCs and
  updates a bunch of drivers to have a better and clearer Device Tree
  definition to support power domains/breaking up of functionality. This
  requires converting the existing watchdog driver into a MFD and then
  breaking up the functionality into separate drivers and finally
  updating the DTS files to leverage the power domains information.

Currently the data structure for llc-slice is devm allocated and
stored as a global but never cleared if the probe function fails.
This is a problem because devm managed memory gets freed on probe
failure the API functions could access the pointer after it has been
freed.

on probe failure or device destroy and add protection to the API
