Subject: [PATCH RFC 3/3] arm64: dts: renesas: rzg2l-smarc: Use versa3 clk for audio mclk
Date: Mon, 20 Feb 2023 13:13:07 +0000	[thread overview]
Message-ID: <20230220131307.269100-4-biju.das.jz@bp.renesas.com> (raw)
In-Reply-To: <20230220131307.269100-1-biju.das.jz@bp.renesas.com>

Currently audio mclk uses a fixed clk 11.2896MHz(multiple of 44.1KHz).
Replace this fixed clk to programmable versa3 clk that can provide
2 rates 11.2896MHz and 12.2880(multiple of 48KHz) based on audio
sampling rate for the playback/record.
