clk: k210: Move k210 clock out of its own subdirectory

2021-06-17T01:40:58Z

Now that we have only one clock driver, we don't need to have our own subdirectory. Move the driver back with the rest of the clock drivers. The MAINTAINERS for kendryte pinctrl is also fixed since it has always been wrong. Signed-off-by: Sean Anderson Reviewed-by: Leo Yu-Chi Liang

clk: k210: Remove bypass driver

2021-06-17T01:40:57Z

This driver no longer serves a purpose now that we have moved away from CCF. Drop it. Signed-off-by: Sean Anderson Reviewed-by: Leo Yu-Chi Liang

clk: k210: Move pll into the rest of the driver

2021-06-17T01:40:57Z

Now that there no separate PLL driver, we can no longer make the PLL functions static. By moving the PLL driver in with the rest of the clock code, we can make these functions static again. We still keep the pll header for unit testing, but it is pretty reduced. Signed-off-by: Sean Anderson Reviewed-by: Leo Yu-Chi Liang

clk: Add K210 clock support

2020-07-01T07:01:21Z

Due to the large number of clocks, I decided to use the CCF. The overall structure is modeled after the imx code. Clocks parameters are stored in several arrays, and are then instantiated at run-time. There are some translation macros (FOOIFY()) which allow for more dense packing.

clk: Add a bypass clock for K210

2020-07-01T07:01:21Z

This is a small driver to do a software bypass of a clock if hardware bypass is not working. I have tried to write this in a generic fashion, so that it could be potentially broken out of the kendryte code at some future date. For the K210, it is used to have aclk bypass pll0 and use in0 instead so that the CPU keeps on working. Signed-off-by: Sean Anderson CC: Lukasz Majewski

clk: Add K210 pll support

2020-07-01T07:01:21Z

This pll code is primarily based on the code from the kendryte standalone sdk in lib/drivers/sysctl.c. k210_pll_calc_config is roughly analogous to the algorithm used to set the pll frequency, but it has been completely rewritten to be fixed-point based.
