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 .../bindings/gpio/gpio-sama5d2-piobu.txt | 23 ++ MAINTAINERS | 7 + drivers/gpio/Kconfig | 10 + drivers/gpio/Makefile | 1 + drivers/gpio/gpio-sama5d2-piobu.c | 254 +++++++++++++++++= ++++ 5 files changed, 295 insertions(+) create mode 100644 Documentation/devicetree/bindings/gpio/gpio-sama5d2-pio= bu.txt create mode 100644 drivers/gpio/gpio-sama5d2-piobu.c --=20 2.7.4
