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], and minor comments on v2[3]. v3 addresses minor issues with comments and debug statements[4], removing remaining references to reset tolerance.
v4 is just a rebase of v3 onto v4.15-rc1, fixing a conflict with the new PIN_CONFIG_SKEW_DELAY pinconf parameter.
Please review!
Andrew
