Subject: [PATCH v2 5/6] clk: starfive: jh7110-sys: Modify PLL clocks source
Date: Thu, 16 Mar 2023 11:05:13 +0800	[thread overview]
Message-ID: <20230316030514.137427-6-xingyu.wu@starfivetech.com> (raw)
In-Reply-To: <20230316030514.137427-1-xingyu.wu@starfivetech.com>

Modify PLL clocks source to be got from dts instead of
the fixed factor clocks.
