Subject: [PATCH] ARM: dts: stm32: Update to generic ADC channel binding on DHSOM systems
Date: Thu, 18 May 2023 04:05:47 +0200 [thread overview]
Message-ID: <20230518020547.487670-1-marex@denx.de> (raw)
The generic ADC channel binding is recommended over legacy one, update the
DT to the modern binding. No functional change. For further details, see
commit which adds the generic binding to STM32 ADC binding document:
664b9879f56ef ("dt-bindings: iio: stm32-adc: add generic channel binding")
Signed-off-by: Marek Vasut <marex@denx.de>
