Using the internal vs. external pull resistors it is possible to get 27 different combinations from 3 strapping pins. Add an implementation of this. This involves updating the sandbox GPIO driver to model external and (weaker) internal pull resistors. The get_value() method now takes account of what is driving a pin: sandbox: GPIOD_EXT_DRIVEN - in which case GPIO_EXT_HIGH provides the value outside source - in which case GPIO_EXT_PULL_UP/DOWN indicates the external state and we work the final state using those flags and the internal GPIOD_PULL_UP/DOWN flags Of course the outside source does not really exist in sandbox. We are just modelling it for test purpose. Signed-off-by: Simon Glass <sjg@chromium.org> |
