2018-12-21gpio: add driver for SAMA5D2 PIOBU pinsAndrei.Stefanescu@microchip.com1-0/+253
PIOBU pins do not lose their voltage during Backup/Self-refresh. This patch adds a simple GPIO controller for them and a maintainer for the driver. This driver adds support for using the pins as GPIO offering the possibility to read/set the voltage.
