[PATCH v2 13/21] arm64: dts: apple: t8103-j45x: Add headset jack nodes

From: James Calligeros

Date: Sun Oct 04 2026 - 02:09:41 EST


The M1 iMacs integrate Apple-specific variants of the TI TAS2770
and Cirrus CS42L42. Since it is not yet safe to expose the speakers
on these machines, add the headset jack nodes and advertise them
to the machine driver via the sound node.
