I2C TYPE_114 On U-boot

[ShaneCCC]

How about the clocks when enable i2c@7000c000 in uboot?

e i2c@7000c000, an

we didn’t add i2c device on i2c@7000c000, we are used i2c@7000c400, and
We had checked it ago, if uboot disbale i2c@7000c400, and kernel dts config 400K, the clk just is 400k from power on.
and if uboot enable i2c@7000c400, and kernel dts config 400K, the clk will be 490k in uboot and change to 400k in kernel from power on.
I think it is the same with i2c@7000c000.

Suppose you can reference to kernel to modify the clock calculating in uboot to try.

Thanks

We want to know why u-boot i2c config is not right.
I think your designer had some considerations. I didn’t konw kernel i2c driver code whether or not valid in u-boot.

[ShaneCCC]

Our designer suggest adapt kernel code to uboot for it.

Thanks

[rd1]

we will try it, thanks!
