Subject: [PATCH 0/3] usb: xhci: Add support for Google XHCI controller
Date: Mon, 19 Feb 2024 14:10:05 +0800 [thread overview]
Message-ID: <20240219061008.1761102-1-pumahsu@google.com> (raw)
In our SoC platform, we support allocating dedicated memory spaces
other than system memory for XHCI, which also requires IOMMU mapping.
The rest of driver probing and executing will use the generic
xhci-plat driver, so we introduce a Google XHCI glue driver.
Besides, we support USB dual roles and switch roles by generic dwc3
driver, but the dwc3 driver always probes xhci-plat driver by hardcode.
We introduce an alternative for probing a XHCI glue driver.
