I'm working on building a "universal" device tree overlay that can be used to enable and switch between most of the various interesting pin functions (uart, timers, spi, gpio, pru in/out, etc). One problem is the BeagleBone specific gpio_of_helper driver designed to make it easy to export GPIO pins via the device tree is forcing a fixed direction of input or output on the GPIO pins.
Before I start hacking on the driver, I'm wondering why the pins weren't either exported with the GPIOF_EXPORT_CHANGEABLE flag set, or why some provision wasn't made to allow specifying the direction could be changed. -- Charles Steinkuehler char...@steinkuehler.net -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
