Subject: [PATCH 0/5] Add support for WD MyCloud EX2 Ultra (+ versatile UART-based restart/poweroff drivers)
Date: Mon, 22 Jul 2019 21:53:00 +0200
Message-ID: <cover.1563822216.git.evgenyz@gmail.com> (raw)
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
