Subject: [PATCH 1/3] arm64: dts: imx8dxl: add adc0 and adc1 support
Date: Fri,  4 Nov 2022 15:21:25 -0400	[thread overview]
Message-ID: <20221104192135.1661541-1-Frank.Li@nxp.com> (raw)

There are two adc controller in 8dxl.
Add adc node at common dma subsystem.
Enable adc0 at imx8dxl_evk boards dts.
