* gpio: omap: Pass correct argument to _get_gpio_direction()Axel Lin2015-02-12-1/+1
| | | | | | | Pass bank rather than bank->base to _get_gpio_direction(). Signed-off-by: Axel Lin <axel.lin@ingics.com> Acked-by: Simon Glass <sjg@chromium.org>
* dm: gpio: omap3: Drop request()/free() in the driverSimon Glass2014-10-23-115/+1
| | | | | | | 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: omap: gpio: Support driver modelSimon Glass2014-10-23-0/+221
| | | | | | | | | | | | Add driver model support to this driver, while retaining support for the legacy system. Driver model GPIO support is enabled with CONFIG_DM_GPIO as usual. Since gpio_is_valid() no longer exists, we can use the -EINVAL error returned from gpio_request(). Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@ti.com>
* dm: omap: gpio: Put _get_gpio_value() logic into its own functionSimon Glass2014-10-23-36/+42
| | | | | | | | | | | | Add a separate internal helper function to get a GPIO value, so that we will be able to call it with the driver model version and avoid code duplication. Also move gpio_get_bank() and check_gpio() down below the helper functions as these won't be needed with driver model.

| | | | | | | | | | | | | | | | | Unlike the other patches in this series so far, this commit fixes a ambiguity in the license terms for some OMAP files: the code was originally derived from the Linux kernel sources, where it was clearly marked as GPL-2.0 (i. e. without the "or later" part), but the U-Boot version had a GPL-2.0+ file header added, apparently without permission / relicensing from the original authors of the code. Insert a GPL-2.0 SPDX-License-Identifier to fix this.

* ARM: OMAP: GPIO: Fix valid range and enable usage of all GPIOs on OMAP5Axel Lin2013-07-02-1/+1
| | | | | | | | | | | | | | | | The omap_gpio driver is used by AM33XX, OMAP3/4, OMAP54XX and DRA7XX SoCs. These SoCs have different gpio count but currently omap_gpio driver uses hard coded 192 which is wrong. This patch fixes this issue by: 1. Move define of OMAP_MAX_GPIO to all arch/arm/include/asm/arch-omap*/gpio.h. 2. Update gpio bank settings and enable GPIO modules 7 & 8 clocks for OMAP5. Thanks for Lubomir Popov to provide valuable comments to fix this issue.
