hi,

We have two submissions which I hope will be helpful to you.

https://patchwork.kernel.org/patch/11272471/
I can see this, I have reconstructed the fractional divider handling
for px30 instead of all rockchiip platforms, is it okay to send
px30-alone fractional div handling support?


A few more notes:
1. DCLK does not recommend the use of fractional frequency divider.
Generally, DCLK will monopolize a PLL, and the relationship between DCLK
frequency and PLL frequency is 1:1.
2, half-div, not all SOC support, detailed need to see TRM.
Can you point me the Page number on TRM?

Jagan.
