From 2bc02355f8ba2c1f108ec8b16a673b467a17228c Mon Sep 17 00:00:00 2001 From: Lee Jones Date: Mon, 17 Jun 2019 13:51:03 +0100 Subject: usb: dwc3: qcom: Add support for booting with ACPI In Linux, the DWC3 core exists as its own independent platform device. Thus when describing relationships in Device Tree, the current default boot configuration table option, the DWC3 core often resides as a child of the platform specific node. Both of which are given their own address space descriptions and the drivers can be mostly agnostic to each other. However, other Operating Systems have taken a more monolithic approach, which is evident in the configuration ACPI tables for the Qualcomm Snapdragon SDM850, where all DWC3 (core and platform) components are described under a single IO memory region. To ensure successful booting using the supplied ACPI tables, we need to devise a way to chop up the address regions provided and subsequently register the DWC3 core with the resultant information, which is precisely what this patch aims to achieve.
