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>

MMC: DWMMC: Correct the CLKDIV register value This patch corrects the divider value written to CLKDIV register. Since SDCLKIN is divided inside controller by the DIVRATIO value set in the CLKSEL register, we need to use the same output clock value to calculate the CLKDIV value. as per user manual: cclk_in = SDCLKIN / (DIVRATIO + 1) Input parameter to mmc_clk is changed to dwmci_host, since we need the same to read DWMCI_CLKSEL register. This improves the read timing values for channel 0 on SMDK5250 from 0.288sec to 0.144sec Signed-off-by: Rajeshwari S Shinde <rajeshwari.s@samsung.com> Acked-by: Jaehoon Chung <jh80.chung@samsung.com> Signed-off-by: Pantelis Antoniou <panto@antoniou-consulting.com>
