clk_set_rate_range() will use the last requested rate for the clock when it calls into the driver set_rate hook. However, if CLK_GET_RATE_NOCACHE is set on that clock, the last requested rate might not be matching the current rate of the clock. In such a case, let's read out ...

tasks 🤔. Or I'm on the wrong track 😄. I hope Rockchip and FriendlyELEC answer soon to get some clarification and a fix forthe writable clk_rate at a minimum MichaIng modified the milestones: v8.14, v8.15 Feb 11, 2023 Owner MichaIng commented Feb 11, 2023 Rockchip ...
