From 00d852326e524214f046a5e1301eee84535a6863 Mon Sep 17 00:00:00 2001 From: Stephan Gerhold Date: Tue, 14 Jan 2020 19:12:29 +0100 Subject: [PATCH] ASoC: msm8916-wcd-analog: Add MIC BIAS Internal3 PM8916 has three TX inputs that each have an (optional) internal RBIAS resistor. MIC BIAS Internal1/2 (for TX1/2) are already supported. TX3 does not have its own MIC BIAS supply, instead it is also supplied from MIC_BIAS1. Now that we have simplified the MIC BIAS Internal* implementation we can easily add support for it: Add a MIC BIAS Internal3 supply that enables the internal RBIAS resistor on TX3, and make sure to also enable the MIC_BIAS1 supply.
