2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini1-2/+1
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>
2018-04-27Remove unnecessary instances of DECLARE_GLOBAL_DATA_PTRTom Rini1-2/+0
We have a large number of places where while we historically referenced gd in the code we no longer do, as well as cases where the code added that line "just in case" during development and never dropped it. Signed-off-by: Tom Rini <trini@konsulko.com>

2017-08-02clk: zynqmp: Add support for CCF driverSiva Durga Prasad Paladugu1-147/+526
Add support for CCF, this CCF reads the ref clocks from dt and checks all the required clock control registers for its source , divisors and calculates the clock from them. This supports clock and set functions. Panic when read/write fails.
