Add clock controller support for the Sophgo CV1800B, CV1812H and SG2000.
Changed from v8:
1. improve code.
2. remove default config in Kconfig.
3. merge patch 2-4 of v8 into one.
Changed from v7:
1. fix unused variables warnings in patch 3 of v7
2. fix wrong pointer type in patch 3 of v7
3. move the clk_disp_vip_parents variable to the patch 5 to avoid warning
Changed from v6:
1. fix dead lock when setting rate.
2. split the driver patch into several patch for easy reading.
Changed from v5:
1. rebased to mainline master tree
2. add SG2000 clock support.
3. fix document link
Changed from v4:
1. improve code for patch 2
2. remove the already applied bindings

Changed from v3:
1. improve comment of patch 3
2. cleanup the include of patch 2
Changed from v2:
1. remove clock-names from bindings.
2. remove clock-frequency node of DT from previous patch.
3. change some unused clock to bypass mode to avoid unlockable PLL.
Changed from v1:
1. fix license issues.

SG2000 series SoC has the same clock as CV1810 series, but the clock
related to A53 is functional in SG2000 series. So a new compatible
string is needed for the new SoC.
Add definition for the clock controller of the SG2000 series SoC.

Add clock generator node for CV1800B and CV1812H.
Until now, It uses DT override to minimize duplication. This may
change in the future. See the last link for the discussion on
maintaining DT of CV1800 series.

Oops, for your information, this last change
([6/6] riscv: dts: sophgo: add uart clock for Sophgo CV1800 series SoC)
breaks my Milk-V Duo S board when I boot it with cv1812h-huashan-pi.dtb
as I believe you suggested.
I don't know whether the board actually boots, but at least I don't get
any more output in the console.
Has someone tested this on the real Huashan Pi board?
Cheers
Michael.

Hi Michael,
I think you boot with the `defconfig` config. This config does
not enable the CV1800 clk support. I think you may need to apply
[1], which enable the clk driver. Also if you want to test sdhci
with real clk, you can try [2]. I test them on the Milk-V Duo S.

Inochi

Indeed, I was using the "defconfig" config. Too used to having
everything working with this configuration on RISC-V :-/
Gotcha for the CONFIG_CLK_SOPHGO_CV1800 setting. However, I'm confused.
Why is this setting available in linux-next, but neither in
git.kernel.org/pub/scm/linux/kernel/git/riscv/linux.git ("master" and
"for-next") nor in github.com/sophgo/linux.git ("master" and "for-next") ?
What's the tree used to push to linux-next?
Cheers
Michael.

I apologize for this mistake. I just forgot this after removing
default value in the Kconfig.

At now, we only maintain the dts related change, but not the driver
code. The driver code is usually applied by the subsystem maintainer.
This is why you only see the clk changes in the linux-next.

As you see, the driver code applied to the clk/for-next. That is the
tree used to push.

I apologize for this mistake. I just forgot this after removing
default value in the Kconfig.

At now, we only maintain the dts related change, but not the driver
code. The driver code is usually applied by the subsystem maintainer.
This is why you only see the clk changes in the linux-next.

It makes perfect sense, thanks!
So, I tried to boot my Milk-V Duo S board with the latest linux-next
kernel (with CONFIG_CLK_SOPHGO_CV1800=y). Here's what I'm getting:

#include "cv1812h.dtsi"

compatible = "milkv,duos", "sophgo,cv1812h";
aliases {
serial0 = &uart0;
};
chosen {
stdout-path = "serial0:115200n8";
};
memory@80000000 {
device_type = "memory";

};
};
&osc {
clock-frequency = <25000000>;
};
&sdhci0 {
status = "okay";
bus-width = <4>;
no-mmc;
no-sdio;
disable-wp;
};
&uart0 {
status = "okay";
};
What's frustrating is that I got the mmc working a few days back :-)
Hoping this helps...
Cheers
