* dm: gpio: Add better functions to request GPIOsSimon Glass2015-01-29-0/+20
| | | | | | | | | | | | | | | | | | | | | | | At present U-Boot sort-of supports the standard way of reading GPIOs from device tree nodes, but the support is incomplete, a bit clunky and only works for GPIO bindings where #gpio-cells is 2. Add new functions to request GPIOs, taking full account of the device tree binding. These permit requesting a GPIO with a simple call like: gpio_request_by_name(dev, "cd-gpios", 0, &desc, GPIOD_IS_IN); This will request the GPIO, looking at the device's node which might be this, for example: cd-gpios = <&gpio TEGRA_GPIO(B, 3) GPIO_ACTIVE_LOW>; The GPIO will be set to input mode in this case and polarity will be honoured by the GPIO calls. It is also possible to request and free a list of GPIOs. Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: gpio: sandbox: Drop request()/free() in the driverSimon Glass2014-10-23-82/+0
| | | | | | | Now that the uclass supports gpio_request/free() there is no need for the driver to implement it too. Drop this unnecessary code. Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: gpio: sandbox: Implement the remove() methodSimon Glass2014-10-23-0/+8
| | | | | | This method frees memory so we must make sure to implement it. Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: gpio: sandbox: Implement the get_function() methodSimon Glass2014-10-23-1/+8
| | | | | | | Implement this method so that the 'gpio' command can do its job correctly. For sandbox we only support input and output states for a gpio. Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: Rename struct device_id to udevice_idSimon Glass2014-06-20-1/+1
| | | | | | | It is best to avoid having any occurence of 'struct device' in driver model, so rename to achieve this. Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: rename device struct to udeviceHeiko Schocher2014-05-27-17/+17
| | | | | | | | | | | | using UBI and DM together leads in compiler error, as both define a "struct device", so rename "struct device" in include/dm/device.h to "struct udevice", as we use linux code (MTD/UBI/UBIFS some USB code,...) and cannot change the linux "struct device" Signed-off-by: Heiko Schocher <hs@denx.de> Cc: Simon Glass <sjg@chromium.org> Cc: Marek Vasut <marex@denx.de>

* sandbox: gpio: add basic driver for simulating GPIOsSimon Glass2012-03-12-0/+209
This provides a way of simulating GPIOs by setting values which are seen by the normal gpio_get/set_value() calls. Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
