Martin Blumenstingl 86aacdca66 clk: meson: mpll: use 64-bit maths in params_from_rate ... "rem * SDM_DEN" can easily overflow on the 32-bit Meson8 and Meson8b SoCs if the "remainder" (after the division operation) is greater than 262143Hz. This is likely to happen since the input clock for the MPLLs on Meson8 and Meson8b is "fixed_pll", which is running at a rate of 2550MHz. One example where this was observed to be problematic was the Ethernet clock calculation (which takes MPLL2 as input). When requesting a rate of 125MHz there is a remainder of 2500000Hz. The resulting MPLL2 rate before this patch was 127488329Hz. The resulting MPLL2 rate after this patch is 124999103Hz. Commit b609338b26 ("clk: meson: mpll: use 64bit math in rate_from_params") already fixed a similar issue in rate_from_params.
