Subject: [PATCH v2 3/3] clk: meson: s4: pll: fix frac maximum value for hifi_pll
Date: Fri, 06 Sep 2024 18:34:42 +0800	[thread overview]
Message-ID: <20240906-fix_clk-v2-3-7a3941eb2cdf@amlogic.com> (raw)
In-Reply-To: <20240906-fix_clk-v2-0-7a3941eb2cdf@amlogic.com>

From: Chuan Liu <chuan.liu@amlogic.com>

The fractional denominator of S4's hifi_pll fractional multiplier is
fixed to 100000.

Fixes: 80344f4c1a1e ("clk: meson: s4: pll: hifi_pll support fractional multiplier")
