[PATCH v2 0/8] ARM: i.MX8M: add nano support

[Ahmad Fatoum]

The i.MX8MN is basically a downsized i.MX8MM, but got also shares
some details with the i.MX8MP. This series adds SoC and EVK board
support. Main thing missing is imx-usb-loader support:

  found i.MX8MN USB device [1fc9:013e]

  4 in err=-7, last_trans=0  00 00 00 00
  status failed

And no serial output indicating PBL started up, but that can
follow later.

v1 -> v2:
  - dropped DDR-1067MHz fix ported from U-Boot in favor
    of Trent's refactor

Ahmad Fatoum (8):
  ARM: i.MX: add i.MX8MN (Nano) SoC support boilerplate
  clk: imx: add i.MX8MN (Nano) support
  ARM: i.MX8MN: adapt early clock support
  ARM: i.MX: extend drivers for i.MX8MN (Nano) support
  ddr: imx8m: add i.MX8MN (Nano) support
  ddr: imx8m: ddrphy_train: add DDR4 support
  scripts: imx: add i.MX8MN support to imx-image
