From ab2806ddad9d94e449f962a15035846c80f89738 Mon Sep 17 00:00:00 2001 From: Olivier Moysan Date: Wed, 12 Oct 2022 16:22:04 +0200 Subject: [PATCH] ARM: dts: stm32: add dummy vdd_adc regulator on stm32mp135f-dk Add a dummy fixed regulator vdd-adc for STM32 ADC, on STM32MP135F-DK board, while SCMI regulators are not available. This patch will have to be removed when SCMI regulator support is added to STM32MP13. This patch intends to allow ADC enabling on STM32MP13. With this patch the ADC can probe but it cannot return valid conversion data, as it's regulator is not actually enabled.
