[PATCH 3/5] gpio: msc313: MStar MSC313 GPIO driver

2020-10-10 Thread Daniel Palmer
This adds a driver that supports the GPIO block found in MStar/SigmaStar ARMv7 SoCs. The controller seems to support 128 lines but where they are wired up differs between chips and no currently known chip uses anywhere near 128 lines so there needs to be some per-chip data to collect together what
