This is the 4th of a few series, the goal of which is to facilitate porting drivers from the linux kernel. Most of the series will be about adding managed API to existing infrastructure (GPIO, reset, phy,...)
This particular series is about GPIOs. It adds a managed API using the API as Linux. To make it 100% compatible with linux, there is a small deviation from u-boot's way of naming the gpio lists: the managed equivalent of gpio_request_by_name(..,"blabla-gpios", ...) is devm_gpiod_get_index(..., "blabla", ...)
