07:04 <urja> There's also the concern that a rate that was never tested could have the device violate EMC certifications (or break the wifi/bt most likely)

07:52 <mmind00> and back in the Chromebook days, we even had devs updating parameters for rates to variants not interfere with hdmi output (I think)

08:02 <a3f> I am not familiar with Rockchip PLLs in particular, but sometimes specific PLL parameters can be changed in a glitch-free manner. A table allows you to chose the initial parameters such that you can optimize the range that you can reach glitchfree

08:02 <a3f> but that's of course no reason against allowing dynamic fallback. The i.MX PLL14xx driver has that for example
