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.

sandbox: dts: add sandbox_pmic.dtsi and include it to sandbox.dts and test.dts This commit adds dtsi file for Sandbox PMIC. It fully describes the PMIC by: - i2c emul node - with a default settings of 16 registers - 2x buck regulator nodes - 2x ldo regulator nodes The default register settings are set with preprocessor macros: - VAL2REG(min[uV/uA], step[uV/uA], val[uV/uA]) - VAL2OMREG(mode id) Both defined in file: - include/dt-bindings/pmic/sandbox_pmic.h The Voltage ranges of each regulator can be found in: - include/power/sandbox_pmic.h The new file is included into: - sandbox.dts - test.dts Signed-off-by: Przemyslaw Marczak <p.marczak@samsung.com> Acked-by: Simon Glass <sjg@chromium.org> Tested on sandbox: Tested-by: Simon Glass <sjg@chromium.org> 2015-05-13 11:38:35 +00:00			`/*`
