* treewide: replace #include <asm/errno.h> with <linux/errno.h>Masahiro Yamada2016-09-23-1/+1
| | | | | | | | | | | Now, arch/${ARCH}/include/asm/errno.h and include/linux/errno.h have the same content. (both just wrap <asm-generic/errno.h>) Replace all include directives for <asm/errno.h> with <linux/errno.h>.

* gpio: add Tegra186 GPIO driverStephen Warren2016-05-31-1/+0
| | | | | | | | | | | | | | Tegra186's GPIO controller register layout is significantly different from previous chips, so add a new driver for it. In fact, there are two different GPIO controllers in Tegra186 that share a similar register layout, but very different port mapping. This driver covers both. The DT binding is already present in the Linux kernel (in linux-next via the Tegra tree so far).

* gpio: rk: remove gpio_xlate routineEric Nelson2016-05-17-11/+0
| | | | | | | | With the addition of GPIO_ACTIVE_LOW parsing in gpio-uclass, the Rockchip gpio driver doesn't need a custom xlate routine. Signed-off-by: Eric Nelson <eric@nelint.com> Acked-by: Simon Glass <sjg@chromium.org>
* dm: Use uclass_first_device_err() where it is usefulSimon Glass2016-03-14-3/+1
| | | | | | Use this new function in places where it simplifies the code. Signed-off-by: Simon Glass <sjg@chromium.org>
* rockchip: gpio: Implement the get_function() methodSimon Glass2016-01-21-4/+36
| | | | | | | Provide this method so that 'gpio status' works fully. It now shows whether a pin is used for input, output or some other function. Signed-off-by: Simon Glass <sjg@chromium.org>
* rockchip: gpio: Read the GPIO value correctlySimon Glass2016-01-21-1/+1
| | | | | | This function should return 0 or 1, not a mask. Fix it. Signed-off-by: Simon Glass <sjg@chromium.org>
* rockchip: gpio: Add rockchip GPIO driverSimon Glass2015-09-02-0/+123
This supports RK3288 at present. It does not implement functions or support for pull up/down. Signed-off-by: Simon Glass <sjg@chromium.org>
