Subject: [PATCH v2 33/65] PCI: dwc: designware: Move register defines to designware header file
Date: Sun, 16 Dec 2018 21:18:53 -0800	[thread overview]
Message-ID: <20181217051925.17582-34-andrew.smirnov@gmail.com> (raw)
In-Reply-To: <20181217051925.17582-1-andrew.smirnov@gmail.com>

Port of a Linux commmit b90dc392212d1153a12eea15cbc6eae352a3c989

  No functional change. Move the register defines and other macros from
  pcie-designware.c to pcie-designware.h. This is in preparation to split the
  pcie-designware.c file into designware core file and host-specific file.

  While at that also fix a checkpatch warning.
