Subject: [PATCH v1 1/4] arm64: dts: imx8: remove non-existent DACs

From: Conor Dooley <conor.dooley@...rochip.com>

Neither the imx8dxl-evk or imx8qm-mek have a Rohm DAC on them as far as
I can tell from online documentation, and they certainly do not have a
dh2228fv, as this device does not actually exist! Remove the DAC nodes
from the devicetrees as it is not acceptable to pretend to have a device
on a board in order to bind the spidev driver in Linux.
