Subject: [PATCH 2/2] arm64: dts: qcom/sdm845-shift-axolotl: Add audio support
Date:   Thu,  9 Jun 2022 11:54:12 +0200
Message-Id: <20220609095412.211060-2-amartinz@shiftphones.com>
In-Reply-To: <20220609095412.211060-1-amartinz@shiftphones.com>

This patch adds audio support for the SHIFT6mq phone.

The primary microphone and headphone jack are handled by the
SDM845 sound card and WCD9340 codec.

The primary speaker needs to go through the TFA9890 speaker
amplifier.
