From: Hans de Goede <hdegoede@xxxxxxxxxx> [ Upstream commit e1317cc9ca4ac20262895fddb065ffda4fc29cfb ] The Voyo Winpad A15 tablet uses a Bay Trail (non CR) SoC, so it is using SSP2 (AIF1) and it mostly works with the defaults. But instead of using DMIC1 it is using an analog mic on IN1, add a quirk for this.
