This patch set is aim to refactor the Mobiveil driver and add
PCIe support for NXP LX series SoCs.

Hou Zhiqiang (23):
  PCI: mobiveil: uniform the register accessors
  PCI: mobiveil: format the code without function change
  PCI: mobiveil: correct the returned error number
  PCI: mobiveil: remove flag MSI_FLAG_MULTI_PCI_MSI
  PCI: mobiveil: correct PCI base address in MEM/IO outbound windows
  PCI: mobiveil: replace the resource list iteration function
  PCI: mobiveil: use WIN_NUM_0 explicitly for CFG outbound window
  PCI: mobiveil: use the 1st inbound window for MEM inbound transactions
  PCI: mobiveil: correct the inbound/outbound window setup routine
  PCI: mobiveil: fix the INTx process error
  PCI: mobiveil: only fixup the Class Code field
  PCI: mobiveil: move out the link up waiting from mobiveil_host_init
  PCI: mobiveil: move irq chained handler setup out of DT parse
  PCI: mobiveil: initialize Primary/Secondary/Subordinate bus number
  dt-bindings: pci: mobiveil: change gpio_slave and apb_csr to optional
  PCI: mobiveil: refactor the Mobiveil driver
  PCI: mobiveil: continue to initialize the host upon no PCIe link
  PCI: mobiveil: disabled IB and OB windows set by bootloader
  PCI: mobiveil: add Byte and Half-Word width register accessors
  PCI: mobiveil: change prototype of function mobiveil_host_init
  dt-bindings: pci: Add NXP LX SoCs PCIe controller
  PCI: mobiveil: add PCIe RC driver for NXP LX series SoCs
  arm64: dts: freescale: lx2160a: add pcie DT nodes

Subrahmanya,

for the records, this is the driver *you* are maintaining, aren't you ?

We ask developers to be added to the MAINTAINERS list in order to hold
them accountable, merging a driver upstream means that you need to
actively maintain it, which in turn means reviewing series affecting
its code, like this one.

I will have a look too but it is your responsibility to review these
patches and ACK them accordingly.

So I strongly suggest you start doing it please.

Thanks,
Lorenzo

Lorenzo,
You are right, I reviewed few DT files, will need some time to review
this train.
I will start doing it in a while.

Thanks for pitching in.

Thanks.
