Subject: [PATCH v1 1/4] arm64: dts: imx8: remove non-existent DACs
Date: Wed, 17 Jul 2024 10:37:53 +0100 [thread overview]
Message-ID: <20240717-alkalize-bouncy-83e748284bc7@spud> (raw)
In-Reply-To: <20240717-anvil-ashy-544e80a1317c@spud>
From: Conor Dooley <conor.dooley@microchip.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.
