Subject: [PATCH 05/10] clk: imx: scu: bypass pi_pll enable status restore
Date: Fri,  4 Jun 2021 17:09:38 +0800	[thread overview]
Message-ID: <20210604090943.3519350-6-aisheng.dong@nxp.com> (raw)
In-Reply-To: <20210604090943.3519350-1-aisheng.dong@nxp.com>

PI PLL does not support enable/disable. So bypass it's
enable status restore.
