Subject: [PATCH v2 1/2] phy: qcom: qmp-usb: Add PM suspend/resume callbacks
Date: Fri, 13 Nov 2026 16:01:10 +0530	[thread overview]
Message-ID: <20261113103111.156476-2-prashanth.k@oss.qualcomm.com> (raw)
In-Reply-To: <20261113103111.156476-1-prashanth.k@oss.qualcomm.com>

Currently when we perform system suspend, the phy clocks aren't
turned off, this leads to power leakage. Prevent this by adding
PM suspend/resume callbacks for the qmp-usb phy which toggles
clocks on/off correspondingly.
