From: Douglas Anderson <dianders@chromium.org> Jitter was improved by lowering the MPLL bandwidth to account for high frequency noise in the rk3288 PLL. In each case MPLL bandwidth was lowered only enough to get us a comfortable margin. We believe that lowering the bandwidth like this is safe given sufficient testing.There are no device-trees that use "rockchip,rk3288-cru", AFAICS..What do you mean? In my tree I have: arch/arm/boot/dts/rk3288.dtsi:863: compatible = "rockchip,rk3288-cru"; drivers/clk/rockchip/clk-rk3288.c:985:CLK_OF_DECLARE(rk3288_cru, "rockchip,rk3288-cru", rk3288_clk_init);
Oh, it is ARM32, I was looking at ARM64 only. My bad.

Was this change tested on a non-RK3288 devices?Yes, on a rk3568 ;) The patch has been posted back in 2015 and was added to the Rockchip downstream kernel in 2016. I don't know how thoroughly Rockchip tests their kernels, but I assume the patch wouldn't be there if it caused any problems.
Thank you for the clarification. _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
