From 2dc6e1a4883a3eba451c76b726c23a580ed05307 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Tue, 2 Jan 2018 19:53:11 +0100 Subject: [PATCH] ASoC: rt5645: set in2_diff flag for GPD win and pocket devices The GPD pocket has a differential signal microphone and needs in2_diff to be set to avoid getting a very noisy signal. Since the GPD pocket and win use the same DMI strings, they share their platform data-definition, so enabling in2_diff on the pocket also sets it on the GPD win. The GPD win has a normal microphone, but setting in2_diff there does not negatively impact the sound from the microphone.
