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>

power: as3722: fix ldo_get/set_enable for ldo index bigger than 7 Fix ldo_get_enable() and ldo_set_enable() functions for LDOs with an index > 7. Turns out there are actually two separate AS3722_LDO_CONTROL registers AS3722_LDO_CONTROL0 and AS3722_LDO_CONTROL1. Actually make use of both. While at it also actually use the enable parameter of the ldo_set_enable() function which now truly allows disabling as opposed to only enabling LDOs.
