Re: [U-Boot] [PATCH V2 18/51] imx8m: add clk support for i.MX8MM

Subject: Re: [U-Boot] [PATCH V2 18/51] imx8m: add clk support for i.MX8MM

Hi Peng,

...

Introduce clk implementation for i.MX8MM, including pll configuration, ccm configuration. Export get_root_clk for CLK UCLASS driver usage.

• clock_enable(CCGR_I2C1 + i2c_num, !!enable);

This is exactly what we want to remove from the legacy U-Boot code base

• the i2c_num index.

First of all this function is a generic one and shall be excluded, not copied (similar instanced of it you will find for: mx53, mx6, mx7 and even mx8).

BUT most of all the problem is with DTS/DM adoption. To operate it correctly you need the index (i2c_num), which is not present in the DTS description.

Instead, you have the udevice, which doesn't need and shouldn't have this information.

SPL_DM is not a must. keep enable_i2c_clk could help non-DM.

By introducing this code you also introduce a hack to convert the I2C controller base address to index, which is wrong. Moreover, the alias doesn't help here as it may be different from the controller (as described here: https://patchwork.ozlabs.org/patch/1019855/).

I had similar problem with eMMC driver (the above link). The only way to do it correctly was to port CCF. And that _was_ the motivation to port it.

With CONFIG_IS_ENABLED(CLK), you could use clk uclass api, right?

Considering the above - I'm against for adding this code for new SoCs.

I would hope not push me to convert to CCF now. I tried to continue CCF after you addressed Simon's comments, but my board not boot up. It costs me too much time on this, I would wait CCF land in mainline and mature, then I reconsider converting i.MX8M.

Regards, Peng.
