Subject: [PATCH 0/3] clk: imx: avoid modify dram pll and improve for pll14xx
Date: Mon, 30 Dec 2019 09:12:56 +0000
Message-ID: <1577696903-27870-1-git-send-email-peng.fan@nxp.com> (raw)

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

Dram PLL is expected to be modified in ATF, so we should
only provide recalc_rate hooks for the PLL.

To avoid add more entries in the pll14xx driver, we could introduce
imx_clk_hw_pll14xx_flags to pass flags.

Peng Fan (3):
  clk: imx: pll14xx: avoid modify dram pll
  clk: imx: pll14xx: introduce imx_clk_hw_pll14xx_flags
  clk: imx: imx8m: use imx_clk_hw_pll14xx_flags for dram pll
