Hello, This series provides an API to configure general GPIO state persistence in gpiolib. Previously, only sleep persistence was considered, but controllers like one found in Aspeed BMCs also support persistence of state across controller resets. There is some prior discussion on v1[1] and the initial RFC[2]. The only change in v2 is to rename the new pinconf property to convey the concept of state persistence rather focussing on reset tolerance, based on feedback from Charles Keepax[3]. Please review!
