Subject: [PATCH v3 2/7] usb: host: xhci-tegra: Add Tegra194 XHCI support
Date: Sat, 5 Oct 2019 00:29:01 +0800
Message-ID: <20191004162906.4818-3-jckuo@nvidia.com> (raw)
In-Reply-To: <20191004162906.4818-1-jckuo@nvidia.com>

This commit adds Tegra194 XUSB host mode controller support. This is
very similar to the existing Tegra124/Tegra210/Tegra186 XHCI, except
  1. the number of ports and PHYs differs
  2. the IPFS wrapper being removed
  3. mailbox registers address changes
