2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
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>
2017-09-14ARM: at91: spl: Add mck function to lower rate while switchingWenyou Yang
Refer to the commit 70f8c8316ad(PMC: add new mck function to lower rate while switching) from AT91Bootstrap. While switching to a lower clock source, we must switch the clock source first instead of last. Otherwise, we could end up with too high frequency on internal bus and peripherals. This happens on SAMA5D2 as exitting from the ROM code. Add a function pmc_mck_init_down() to allow this sequence.

2016-09-23treewide: replace #include <asm/errno.h> with <linux/errno.h>Masahiro Yamada
Now, arch/${ARCH}/include/asm/errno.h and include/linux/errno.h have the same content. (both just wrap <asm-generic/errno.h>) Replace all include directives for <asm/errno.h> with <linux/errno.h>.

2016-02-18ARM: at91: clock: add a new file to handle clockWenyou Yang
To reduce the duplicated code, add a new file to accommodate the peripheral's and system's clock handle code, shared with the SoCs with different ARM core.

2015-11-03arm: at91: clock: Add the generated clock supportWenyou Yang
Some peripherals may need a second clock source that may be different from the system clock. This second clock is the generated clock (GCK) and is managed by the PMC via PMC_PCR. For simplicity, the clock source of the GCK is fixed to PLLA_CLK. Signed-off-by: Wenyou Yang <wenyou.yang@atmel.com> Reviewed-by: Andreas Bießmann <andreas.devel@googlemail.com>
