[PATCH v2 0/4] add the imx8 pcie phy driver support

[Richard Zhu]

Refer to the discussion [1] when try to enable i.MX8MM PCIe support,
one standalone PCIe PHY driver should be seperated from i.MX PCIe
driver when enable i.MX8MM PCIe support.

This patch-set adds the standalone PCIe PHY driver suport, and as a
preparatory to add the i.MX8MM PCIe support later.

The PCIe works on i.MX8MM EVK board based the the blkctrl power driver
[2] and this PHY driver patch-set.
