Subject: arm64: dts: mt8173: Fix auxadc node
From: Matthias Brugger <matthias.bgg@xxxxxxxxx>
commit a3207d644fb89e5d7d5e01f00c04dcfc6d2d44d5 upstream.
The devicetree node for mt8173-auxadc lacks the clock and
io-channel-cells property. This leads to a non-working driver.
mt6577-auxadc 11001000.auxadc: failed to get auxadc clock
mt6577-auxadc: probe of 11001000.auxadc failed with error -2
Fix these fields to get the device up and running.
Fixes: 748c7d4de46a ("ARM64: dts: mt8173: Add thermal/auxadc device
nodes")
