Subject: [PATCH 2/3] usb: ucsi: ccg: disable runtime pm during fw flashing
Date: Mon, 17 Feb 2020 17:49:12 +0300 [thread overview]
Message-ID: <20200217144913.55330-3-heikki.krogerus@linux.intel.com> (raw)
In-Reply-To: <20200217144913.55330-1-heikki.krogerus@linux.intel.com>
From: Ajay Gupta <ajayg@nvidia.com>
Ucsi ppm is unregistered during fw flashing so disable
runtime pm also and reenable after fw flashing is completed
and ppm is re-registered.
