2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
2015-08-12gpio: omap: Drop 'method' parameterTom Rini
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>
2014-10-23dm: omap: gpio: Support driver modelSimon Glass
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>
2013-08-19SPDX-License-Identifier: fixing some problematic GPL-2.0 filesWolfgang Denk
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.

2011-09-13omap: gpio: Use generic APISanjeev Premi
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.
