Subject: [PATCH 2/5] dt-bindings: usb: xhci-tegra: Add power-domain details
Date: Wed, 26 Sep 2018 13:27:35 +0100 [thread overview]
Message-ID: <1537964858-30332-3-git-send-email-jonathanh@nvidia.com> (raw)
In-Reply-To: <1537964858-30332-1-git-send-email-jonathanh@nvidia.com>
Add details for power-domains to the Tegra xHCI bindings so that
generic power-domains can be used for inconjunction with the xHCI
driver.
