Subject: [PATCH 2/2] usb: ucsi: ccg: disable runtime pm during fw flashing
Date: Wed, 15 Jan 2020 17:32:47 -0800
Message-ID: <20200116013247.16507-2-ajayg@nvidia.com> (raw)
In-Reply-To: <20200116013247.16507-1-ajayg@nvidia.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.
