hi, We have two submissions which I hope will be helpful to you. https://patchwork.kernel.org/patch/11272465/ https://patchwork.kernel.org/patch/11272471/ A few more notes: 1. DCLK does not recommend the use of fractional frequency divider. Generally, DCLK will monopolize a PLL, and the relat

[PATCH] clk: rockchip: Fix overflow rate during fractional approximation

The current rockchip fractional approximation overflow the desired rate if parent rate is lower than the (rate * 20) for few clocks like dclk_vopb_frac. The overflow condition has observed in px30 for dclk_vopb_frac clock with an input rate of 71.1MHz and parent rate of 24MHz is, [2.543280] r
