Subject: [PATCH v3 7/9] ARM: dts: mediatek: mt2701: wire HDMI audio path clocks into AFE
Date: Fri, 24 Apr 2026 03:50:35 +0100 [thread overview]
Message-ID: <99fb10ae55dd26e1086b6d865f2f12d75dc7ac61.1776998727.git.daniel@makrotopia.org> (raw)
In-Reply-To: <cover.1776998727.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.
