Subject: [PATCH v1] PCI: qcom: Fix incorrect register offset in pcie init
Date: Fri, 15 Oct 2021 00:28:49 +0530	[thread overview]
Message-ID: <1634237929-25459-1-git-send-email-pmaliset@codeaurora.org> (raw)

In pcie_init_2_7_0 one of the register writes using incorrect offset
as per the platform register definitions (PCIE_PARF_AXI_MSTR_WR_ADDR_HALT
offset value should be 0x1A8 instead 0x178).
Update the correct offset value for SDM845 platform.

fixes: ed8cc3b1 ("PCI: qcom: Add support for SDM845 PCIe controller")
