From 765ce359d67fc089281bc5317230c310122f7a32 Mon Sep 17 00:00:00 2001 From: Olivier Moysan Date: Tue, 30 May 2023 14:45:33 +0200 Subject: ARM: dts: stm32: adopt generic iio bindings for adc channels on stm32mp157c-ed1 Use STM32 ADC generic bindings instead of legacy bindings on STM32MP157c-ed1 board. The STM32 ADC specific binding to declare channels has been deprecated, hence adopt the generic IIO channels bindings, instead. The STM32MP151 device tree now exposes internal channels using the generic binding. This makes the change mandatory here to avoid a mixed use of legacy and generic binding, which is not supported by the driver.
