Simon Glass 96495d90fe dm: Add GPIO support and tests ... Add driver model support for GPIOs. Since existing GPIO drivers do not use driver model, this feature must be enabled by CONFIG_DM_GPIO. After all GPO drivers are converted over we can perhaps remove this config. Tests are provided for the sandbox implementation, and are a sufficient sanity check for basic operation. The GPIO uclass understands the concept of named banks of GPIOs, with each GPIO device providing a single bank. Within each bank the GPIOs are numbered using an offset from 0 to n-1. For example a bank named 'b' with 20 offsets will provide GPIOs named b0 to b19. Anonymous GPIO banks are also supported, and are just numbered without any prefix. Each time a GPIO driver is added to the uclass, the GPIOs are renumbered accordinging, so there is always a global GPIO numbering order.
