From 44525a456296a47150292aacb0748366f42dc5e6 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Sun, 2 Mar 2025 16:25:14 +0100 Subject: [PATCH] ARM: dts: stm32: Add support for STM32MP13xx DHCOR SoM and DHSBC rev.200 board LDO2 is expansion connector supply on STM32MP13xx DHCOR DHSBC rev.200. LDO5 is carrier board supply on STM32MP13xx DHCOR DHSBC rev.200. Keep both regulators always enabled to make sure both the carrier board and the expansion connector is always powered on and supplied with correct voltage. Describe ST33TPHF2XSPI TPM 2.0 chip interrupt and reset lines.
