Hi Shawn,

After merging the imx-mxs tree, today's linux-next build (arm
multi_v7_defconfig) failed like this:

drivers/clk/imx/clk.c: In function 'imx_mmdc_mask_handshake':
drivers/clk/imx/clk.c:20:8: error: implicit declaration of function 'readl_relaxed'; did you mean 'xchg_relaxed'? [-Werror=implicit-function-declaration]
  reg = readl_relaxed(ccm_base + CCM_CCDR);
        ^~~~~~~~~~~~~
        xchg_relaxed
drivers/clk/imx/clk.c:22:2: error: implicit declaration of function 'writel_relaxed'; did you mean 'xchg_relaxed'? [-Werror=implicit-function-declaration]
  writel_relaxed(reg, ccm_base + CCM_CCDR);
  ^~~~~~~~~~~~~~
  xchg_relaxed

Caused by commit

  0dc6b492b6e0 ("clk: imx: Add common API for masking MMDC handshake")

I have used the imx-mxs tree from next-20190520 for today.
