Subject[PATCH 0/3] add sama5d2 PIOBU GPIO driver
Date
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

Andrei Stefanescu (3):
dt-bindings: gpio: add sama5d2 PIOBU support
MAINTAINERS: add maintainer for sama5d2 PIOBU GPIO driver
gpio: added driver for sama5d2 PIOBU pins
