This patch-set adds the standalone PCIe PHY driver suport[1-5], and i.MX8MM PCIe support[6-9] to have whole view to review this patch-set. The PCIe works on i.MX8MM EVK board based the the blkctrl power driver [2] and this PHY driver patch-set.

Changes v1 --> v2: - Update the license of the dt-binding header file to make the license compatible with dts files. - Fix the dt_binding_check errors.
