Subject: [PATCH 3/3] i2c: enable async suspend/resume on i2c client devices
Date: Mon, 25 Oct 2021 14:35:31 -0700 [thread overview]
Message-ID: <20211025213532.2349161-4-rajatja@google.com> (raw)
In-Reply-To: <20211025213532.2349161-1-rajatja@google.com>
From: Derek Basehore <dbasehore@chromium.org>
This enables the async suspend for i2c client devices. This reduces
the suspend/resume time considerably on platforms where i2c devices
can take a lot of time (hundreds of ms) to resume.
