From 8ffaa6a136e6f30e053e78fb9742c7748bef8576 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Sun, 4 Mar 2018 15:36:02 +0100 Subject: [PATCH] ASoC: Intel: bytcr_rt5651: Add quirk micbias OVCD configuration Add support for setting the micbias OVCD limits device-properties through quirks. And set the limits for this to 2000uA with a scale-factor of 0.75 for the KIANO SlimNote 14.2 device, which is the only device on which jack-detection is currently enabled.
