From 62ba9a86eac78e21a13b71c36a006d8c99d87270 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Cl=C3=A9ment=20Le=20Goffic?= Date: Fri, 11 Jul 2025 09:41:23 +0200 Subject: [PATCH] ARM: dts: stm32: add Hardware debug port (HDP) on stm32mp15 MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Add the hdp devicetree node for stm32mp15 SoC family Keep the node disabled as HDP needs the pinctrl SoC configuration to be able to output its mux output signal outside of the SoC, on the SoC pad. This configuration is provided in the board dtsi file through 'pinctrl-*' properties as well as HDP mux configuration. Thus, if needed, HDP should be enabled in board dtsi file.
