Subject: [PATCH v2 7/9] ARM: dts: mediatek: mt2701: wire HDMI audio path clocks into AFE
Date: Mon, 20 Apr 2026 02:13:48 +0100	[thread overview]
Message-ID: <29da9abd86362471bacae22cbd07ae63f742b048.1776646435.git.daniel@makrotopia.org> (raw)
In-Reply-To: <cover.1776646435.git.daniel@makrotopia.org>

Add the HADDS2 PLL 294 MHz root, the audio_hdmi and audio_spdf
interface gates and the audio_apll gate to the MT2701 AFE node,
and reparent the AUDPLL mux to HADDS2PLL_98M so the HDMI audio
serial clock path has a stable 294.912 MHz source. The clock
names match the updated mediatek,mt2701-audio binding.
