k210: use the board vendor name rather than the marketing name

2022-03-15T09:43:11+00:00

"kendryte" is the marketing name for the K210 RISC-V SoC produced by
Canaan Inc. Rather than "kendryte,k210", use the usual "canaan,k210"
vendor,SoC compatibility string format in the device tree files and
use the SoC name for file names.
With these changes, the device tree files are more in sync with the
Linux kernel DTS and drivers, making uboot device tree usable by the
kernel.

clk: ccf: correct the test on the parent uclass in clk_enable/clk_disable

2022-02-25T06:41:04+00:00

It is safe to check if the uclass id on the device is UCLASS_CLK
before to call the clk_ functions, but today this comparison is
not done on the device used in API: clkp->dev->parent
but on the device himself: clkp->dev.

This patch corrects this behavior and tests if the parent device
is a clock device before to call the clock API, clk_enable or
clk_disable, on this device.

clk: Add clk_get_by_name_optional

2022-02-25T06:41:04+00:00

This adds a helper function for clk_get_by_name in cases where the clock is
optional. Hopefully this helps point driver writers in the right direction.
Also convert some existing users.

clk: Inline clk_get_*_optional

2022-02-25T04:58:13+00:00

The optional varients of clk_get_* functions are just simple wrappers.
Reduce code size a bit by inlining them. On platforms where it is not used
(most of them), it will not be compiled in any more. On platforms where
they are used, the inlined branch should not cause any significant growth.

This xlate function just performs some checking. We can do this in
request() instead and use the default xlate.
