[PATCH 4/4] clk: meson: s4: pll: hifi_pll frequency is not accurate

From: Chuan Liu via B4 Relay
Date: Fri Sep 06 2024 - 01:53:02 EST


From: Chuan Liu <chuan.liu@xxxxxxxxxxx>

The fractional denominator of S4's hifi_pll fractional multiplier is
fixed to 100000, so flag CLK_MESON_PLL_FIXED_FRAC_MAX is added.
