Subject: [PATCH v7 RESEND 1/3] PCI: xilinx-cpm: Move interrupt bit definitions to common header
Date: Tue, 3 Oct 2023 23:04:51 +0530 [thread overview]
Message-ID: <20231003173453.938190-2-thippeswamy.havalige@amd.com> (raw)
In-Reply-To: <20231003173453.938190-1-thippeswamy.havalige@amd.com>
Rename Xilinx interrupt bit definitions so they are not CPM-specific. Move
the definitions to pcie-xilinx-common.h where they can be shared between
pcie-xilinx-cpm and the new xilinx-xdma driver.
