From 5b7ec7fb4437e3e9b50127114a59796a90c1681a Mon Sep 17 00:00:00 2001 From: Neil Armstrong Date: Mon, 25 Nov 2024 10:46:17 +0100 Subject: pci: Add support for Qualcomm PCIe controller Add support for the PCIe busses on Qualcomm platforms, by using the pcie_dw_common infrastructure. The driver is based on the Linux driver but only supporting the "1_9_0" and compatible platforms like: - sa8540p - sc7280 - sc8180x - sc8280xp - sdm845 - sdx55 - sm8150 - sm8250 - sm8350 - sm8450 - sm8550 - sm8650 - x1e80100 But it has only been tested on: - sc7280 - sm8550 - sm8650 - x1e80100 It supports setting the IOMMU SID table for supported platforms.
