Subject: [PATCH 3/3] clk: imx: imx8m: use imx_clk_hw_pll14xx_flags for dram pll
Date: Mon, 30 Dec 2019 09:13:10 +0000
Message-ID: <1577696903-27870-4-git-send-email-peng.fan@nxp.com> (raw)
In-Reply-To: <1577696903-27870-1-git-send-email-peng.fan@nxp.com>

From: Peng Fan <peng.fan@nxp.com>

Use imx_clk_hw_pll14xx_flags for dram pll.
Modify imx_1443x_dram_pll to imx_1443x_dram_readonly, because dram pll
is not expected to be modified from Linux.
