Subject: [PATCH 0/4] Add support for HiSilicon PCIe Tune and Trace device

HiSilicon PCIe tune and trace device(PTT) is a PCIe Root Complex
integrated Endpoint(RCiEP) device, providing the capability
to dynamically monitor and tune the PCIe traffic(tune),
and trace the TLP headers(trace). The driver exposes the user
interface through debugfs, so no need for extra user space tools.
The usage is described in the document.

Yicong Yang (4):
  hwtracing: Add trace function support for HiSilicon PCIe Tune and
    Trace device
  hwtracing: Add tune function support for HiSilicon PCIe Tune and Trace
    device
  docs: Add documentation for HiSilicon PTT device driver
  MAINTAINERS: Add maintainer for HiSilicon PTT driver
