Subject: [RFC v2 0/5] PCIE support for i.MX8MQ (DT changes)

Everyone:

This series contains all of the i.MX Device Tree changes I made to
enable support of PCIe on i.MX8MQ EVK. Marked as RFC since "arm64:
dts: imx8mq-evk: Enable PCIE0 interface" contains proposed AUX clock
binding that is not part of the PCI tree yet (to be submitted once we
agree on this RFC).

NOTE: Immutable brach containing imx8mq-reset.h used in "arm64: dts:
Add nodes for PCIe IP blocks" is availible in [reset-imx8mq]

Feedback is welcome!

Changes since [v1]:

    - Dropped unsupported IRQ from PCIe nodes (a leftover from vendor tree)

    - Added "pcie_aux" clock and moved clock configuration to board
      file since "pcie_bus" clock is now board specific

Thanks,
Andrey Smirnov
