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.

Tegra2: Add more clock support This adds functions to enable/disable clocks and reset to on-chip peripherals. Signed-off-by: Simon Glass <sjg@chromium.org> 2011-08-30 06:23:13 +00:00			`/*`

Tegra20: Move some include files to arch-tegra for sharing with Tegra30 The move is pretty straight-forward. ap20.h and tegra20.h were renamed to ap.h and tegra.h. Some files remain in arch-tegra20 but 'include' a file in 'arch-tegra' with #defines & structs that will be common between T20 and T30 HW. HW-specific #defines, etc. stay in the 'arch-tegra20' 'root' file. All boards build OK w/MAKEALL -s tegra20. Checkpatch.pl runs clean. Seaboard works OK.

Tegra: Move common clock code to arch/arm/cpu/tegra-common/clock.c This 'commonizes' much of the clock/pll code. SoC-dependent code and tables are left in arch/cpu/tegraXXX-common/clock.c Some T30 tables needed whitespace fixes due to checkpatch complaints.

ARM: tegra: Implement tegra_plle_enable() This function is required by PCIe and SATA. This patch implements it on Tegra20, Tegra30 and Tegra124. It isn't implemented for Tegra114 because it doesn't support PCIe or SATA.
