* gpio: omap: Drop 'method' parameterTom Rini2015-08-12-6/+1
| | | | | | | | | | The "method" parameter was part of the original port of the driver from the kernel. At some point this may have been added to allow for future differentiation (as omap1 and omap2 have different GPIO IP blocks, so this wasn't an unreasonable thing to do). At this point however it's just extra overhead, so drop. Signed-off-by: Tom Rini <trini@konsulko.com>
* dm: omap: gpio: Support driver modelSimon Glass2014-10-23-2/+17
| | | | | | | | | | | | 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>
* SPDX-License-Identifier: fixing some problematic GPL-2.0 filesWolfgang Denk2013-08-19-18/+1
| | | | | | | | | | | | | | | | | 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.

* omap: gpio: Use generic APISanjeev Premi2011-09-13-15/+0
| | | | | | | | | | | | | | | Convert all OMAP specific functions to use the common API definitions in include/asm/gpio.h. In the process, made few additional changes: - Use -EINVAL consistently. -1 was used in many places. - Removed one-liner static functions that were used only once. Replaced the content as necessary. - Combines implementation of functions omap_get_gpio_dataout() and omap_get_gpio_datain(). To do so, new static function _get_gpio_direction() was added.
