* clk: at91: clk-system: add driver compatible with ccfClaudiu Beznea2020-09-221-0/+112
| | | | | | Add clk-system driver compatible with common clock framework. Signed-off-by: Claudiu Beznea <claudiu.beznea@microchip.com>
* clk: at91: move clock code to compat.cClaudiu Beznea2020-09-221-111/+0
| | | | | | | | Move clock code to compat.c to allow switching to CCF without mixing CCF code with non CCF code. This prepares the field for next commits. Signed-off-by: Claudiu Beznea <claudiu.beznea@microchip.com>

* SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini2018-05-071-2/+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>
* clk: at91: clk-system: add set/get_rate operationsWenyou Yang2018-03-161-0/+26
| | | | | | To support set/get the clock rate, add set/get_rate operations. Signed-off-by: Wenyou Yang <wenyou.yang@microchip.com>
* dm: Use dm.h header when driver mode is usedSimon Glass2017-06-011-1/+1
| | | | | | | | This header includes things that are needed to make driver build. Adjust existing users to include that always, even if other dm/ includes are present Signed-off-by: Simon Glass <sjg@chromium.org>
* clk: at91: Improve the clock implementationWenyou Yang2016-10-281-24/+33
| | | | | | | | | | | | | | | For the peripheral clock, provide the clock ops for the clock provider, such as spi0_clk. The .of_xlate is to get the clk->id, the .enable is to enable the spi0 peripheral clock, the .get_rate is to get the clock frequency. The driver for periph32ck node is responsible for recursively binding its children as clk devices, not provide the clock ops. So do the generated clock and system clock.

* clk: at91: Add clock driverWenyou Yang2016-08-151-0/+76
The patch is referred to at91 clock driver of Linux, to make the clock node descriptions in DT aligned with the Linux's. Signed-off-by: Wenyou Yang <wenyou.yang@atmel.com> Reviewed-by: Simon Glass <sjg@chromium.org>
