Subject: [PATCH v3 5/6] ASoC: meson: s4: Add s4 tocodec driver
Date: Fri, 28 Feb 2025 16:04:13 +0800	[thread overview]
Message-ID: <20250228-audio_drvier-v3-5-dbfd30507e4c@amlogic.com> (raw)
In-Reply-To: <20250228-audio_drvier-v3-0-dbfd30507e4c@amlogic.com>

From: jiebing chen <jiebing.chen@amlogic.com>

S4 tocodec support 8 lane to input, It need to enable
bclk and mclk control bit when work
