SPDX: Convert all of our single license tags to Linux Kernel style 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> 2018-05-06 21:58:06 +00:00			`// SPDX-License-Identifier: GPL-2.0+`
ARM: uniphier: consolidate NAND pin-mux settings The NAND subsystem has not supported the Driver Model yet, but the NAND pin-mux data are already in the pinctrl drivers. Use them by calling pinctrl_generic_set_state() directly. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> 2016-09-16 18:33:04 +00:00			`/*`

dm: Fix up inclusion of common.h It is good practice to include common.h as the first header. This ensures that required features like the DECLARE_GLOBAL_DATA_PTR macro, configuration options and common types are available. Fix up some files which currently don't do this. This is necessary because driver model will soon start using global data and configuration in the dm/read.h header file, included via dm.h. The gd->fdt_blob value will be used to access the device tree and CONFIG options will be used to determine whether to support inline functions in the header file.

ARM: uniphier: replace <linux/err.h> with <linux/errno.h> These files only need error number macros. Actually, IS_ERR(), PTR_ERR(), ERR_PTR(), etc. are not useful for U-Boot.
