gpio: Add a simple GPIO API for SPL 2019-02-01T15:59:12+00:00 Simon Glass sjg@chromium.org 2019-01-21T21:53:21+00:00 5c01d1c0d0e673dbd5739256e77e9dca9dc74816 In space-constrained environments or before driver model is available, it is sometimes necessary to set GPIO values. Add an SPL API for this, to allow early board code to change GPIOs. The caller must provide the register address, so that the drivers can be fairly generic. This API can be implemented by GPIO drivers, behind a suitable guard, like #ifdef CONFIG_SPL_BUILD.
