Hello, These two patches try to improve open-drain and open-source (collectively referred to as single-ended) GPIO support in the gpiolib core.
The first patch splits GPIO flag parsing and GPIO configuration into two operation to allow gpiochip drivers to reject GPIO requests with flags that don't match the device capabilities. The second patch builds on top of "[PATCH v2] gpio: add DT bindings for existing consumer flags" (http://marc.info/?l=linux-gpio&m=144378527414721&w=2) to enable usage of the single-ended flag.
