[PATCH] clk: meson: s4: fix fixed_pll_dco clock

From: Xianwei Zhao via B4 Relay
Date: Mon Jun 03 2024 - 06:04:43 EST


From: Xianwei Zhao <xianwei.zhao@xxxxxxxxxxx>

The fixed_pll_dco output frequency is not accurate,
add frac factor for fixed_pll_dco clk to fix it.

Fixes: 57b55c76aaf1 ("clk: meson: S4: add support for Amlogic S4 SoC peripheral clock controller")
