Subject: [PATCH 3/3] arm64: dts: ti: am625-sk: Add audio output support
Date: Thu, 21 Apr 2022 18:52:24 +0530 [thread overview]
Message-ID: <20220421132224.8601-4-j-luthra@ti.com> (raw)
In-Reply-To: <20220421132224.8601-1-j-luthra@ti.com>
Add nodes for audio codec and sound card, enable the audio serializer
(McASP1) under use and update pinmux. Disable all other McASP nodes.
Audio input is currently not working properly, so the RX port on McASP1
is disabled for now, until the issue is debugged.
The serializer is shared between HDMI and codec. By default codec is
used for output, but it can be toggled to HDMI using a FET switch
connected to the MCASP1_FET_SEL (J24) header on the board.
