Subject: [PATCH v2 0/2] Add the PM suspend/resume callbacks for qmp phys
Date: Fri, 13 Nov 2026 16:01:09 +0530	[thread overview]
Message-ID: <20261113103111.156476-1-prashanth.k@oss.qualcomm.com> (raw)

From: Prashanth K <prashk@qti.qualcomm.com>

Currently the phy clocks are left ON during system suspend, this leading to
power leakages. Prevent this by disabling the phy clocks during PM suspend.

Changes in v2:
 - Added pm_runtime_force_suspend for pm callbacks.
 - Added mutex to prevent race between typec/mux callbacks with suspend/resume.
 - Link to v1: https://lore.kernel.org/all/20261022104321.306679-1-prashanth.k@oss.qualcomm.com/
