| |
As of v5.7-rc2, Linux now prints the following message at boot:
[ 33.848525] platform sound_spdif: deferred probe pending
This is because sound_spdif is waiting on its CPU DAI &spdif to probe, but &spdif is disabled in the device tree.
Exposure of the SPDIF pin is board-specific functionality, so the sound card and codec DAI belong in the individual board DTS, not the SoC DTSI. In fact, no in-tree A64 board DTS enables &spdif, so let's remove the card and DAI entirely.
This reverts commit 78e071370a86473f25923e03b51cbbadacf8be0f.

Changes since v1: - Remove the node instead of disabling it - Also remove the codec DAI
