Subject: [PATCH 0/5] Add support for WD MyCloud EX2 Ultra (+ versatile UART-based restart/poweroff drivers)

This patchset consists of the DTS, which describes the WD MyCloud EX2 Ultra device,
'poweroff' and 'resert' drivers for power-managing MCUs connected to a board via UART
(these drivers are more versatile than qnap-poweroff and could be used as a substitude),
and DT bindings for these drivers.

The difference between uart-poweroff and qnap-poweroff is small, but important:
uart-poweroff is able to send to an MCU a command of arbitrary length, and the command
itself is defined in a DTS file for a specific device/board, thus making this driver
applicable to wider range of devices.

Evgeny Kolesnikov (5):
  power: reset: Add UART-based MCU poweroff DT bindings
  power: reset: Add UART-based MCU restart DT bindings
  power/reset: Add a power off driver for UART-based PM MCUs
  power/reset: Add a restart driver for UART-based PM MCUs
  ARM: dts: armada385-wd-mcex2u: Add DTS file for WD My Cloud EX2 Ultra
