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.
