Subject: [PATCH 3/3] clk: imx: imx8mq: mark sys1/2_pll as fixed clock
Date: Wed, 9 Oct 2019 09:58:24 +0000 [thread overview]
Message-ID: <1570614940-17239-3-git-send-email-peng.fan@nxp.com> (raw)
In-Reply-To: <1570614940-17239-1-git-send-email-peng.fan@nxp.com>
From: Peng Fan <peng.fan@nxp.com>
According Architecture definition guide, SYS1_PLL is fixed at
800MHz, SYS2_PLL is fixed at 1000MHz, so let's use imx_clk_fixed
to register the clocks and drop code that could change the rate.
