Universal Serial Interface (USI) supports three types of serial interface
such as Universal Asynchronous Receiver and Transmitter (UART), Serial
Peripheral Interface (SPI), and Inter-Integrated Circuit (I2C).
Each protocols can be working independently and configured as one of
those using external configuration inputs.
Exynos Auto v9 SoC support 12 USIs. When a USI uses two pins such as i2c
and 3 wire uarts(RX/TX only), we can use remain two pins as i2c mode.
So, we can define one USI node that includes serial/spi and hsi2c.
usi_i2c nodes can be used only for i2c mode.

We can have below combinations for one USI.
1) The usi node is used either 4 pin uart or 4 pin spi
 -> No usi_i2c can be used
2) The usi node is used 2 pin uart(RX/TX) and i2c(SDA/SCL)
 -> usi_i2c should be enabled to use the latter i2c
3) The usi node is used i2c(SDA/SCL) and i2c(SDA/SCL)
 -> usi_i2c should be enabled to use the latter i2c

By default, all USIs are initially set to uart mode by below setting.
samsung,mode = <USI_V2_UART>;
You can change it either USI_V2_SPI or USI_V2_I2C.

Put all this directly in exynosautov9.dtsi, because this is not a
re-usable piece among different DTSI.

We should start adding dedicated compatible, so:
"samsung,exynosautov9-usi", "samsung,exynos850-usi"

Skip the comments, they are obvious from device node name. Long time ago
I was not advocating this, but I see it's benefits - much easier to
introduce changes to DTS or binding in case of some differences.

Okay. I'll move them in the exynosautov9.dtsi. I thought they're too long to put in the exynosautov9.dtsi and I also found a similar case such as exynos5433-bus.dtsi and exynos5433-tmu.dtsi.

So, I need to add the compatible to the Documentation/devicetree/bindings/soc/samsung/exynos-usi.yaml, right?

- samsung,exynos850-usi   # for USIv2 (Exynos850, ExynosAutoV9)

To be>
- samsung,exynos850-usi
- samsung,exynosautov9-usi

I'll drop them.

I'll add "samsung,exynosautov9-uart" to the yaml file.

I'll separate it.

Indeed we did like that... The tmu maybe was meant to be re-used,
although it references specific clusters. But the split of bus I don't
understand - it does not help.

I don't think it improved readability.

Eh, I think my reply got mixed up. The last sentence was about
compatible, so it should be:

We should start adding dedicated compatible, so:
"samsung,exynosautov9-usi", "samsung,exynos850-usi".
Long time ago I was not advocating this, but I see it's benefits - much
easier to introduce changes to DTS or binding in case of some differences.

and here only about the comment.
