Subject: [patch v3 0/4] Add edac driver for i.MX8MP based on synopsys edac driver

This patchset add edac driver support for i.MX8MP, since i.MX8MP use the same
synopsys memory controller with ZynqMP, so the driver is based on synopsys_edac
driver.

Considering that i.MX8MP dts file is still in kernel/git/shawnguo/linux.git and
isn't in mainline now, I will add EDAC node in i.MX8MP dts after this file is
pushed to mainline. 

And the edac driver for i.MX8MP has been tested in kernel/git/shawnguo/linux.git
where i.MX8MP is supported, it turns out that this driver works well to detect
corrected and uncorrected errors for LPDDR4 in i.MX8MP.

Changes since v2:
=================
- Use u64 data instead u32 data_low and u32 data_high as robert suggested in
patch 4/4.
- Add edac_dbg() for the != DEV_X8 cases in zynqmp_get_error_info() in patch
4/4.
- Change the format of the output data to avoid build warnings in patch 4/4.

Changes since v1:
=================
- Reorganized the patchset, no content changes. 

Sherry Sun (4):
  dt-bindings: memory-controllers: Add i.MX8MP DDRC binding doc
  EDAC: Add synopsys edac driver support for i.MX8MP
  EDAC: synopsys: Add edac driver support for i.MX8MP
  EDAC: synopsys: Add useful debug and output information for 64bit
    systems
