Subject: [PATCH 0/3] add sama5d2 PIOBU GPIO driver
Date: Wed, 7 Nov 2018 15:12:24 +0000 [thread overview]
Message-ID: <1541603580-17448-1-git-send-email-andrei.stefanescu@microchip.com> (raw)
On sama5d2 SoC the PIOBU pins do not lose their
voltage during Backup/Self-refresh mode. This can
be useful, for example, when the voltage must remain
positive for a peripheral during Backup/Self-refresh
mode (suspend-to ram is the Linux equivalent state).
This patch series:
- documents the driver's necessary device tree bindings
- adds a MAINTAINER for the driver,
- provides a basic GPIO controller driver for them
