From d0647b20d1e19a6d8dc44e57d2d453610c0f29f2 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Cl=C3=A9ment=20Le=20Goffic?= Date: Fri, 11 Jul 2025 09:41:26 +0200 Subject: [PATCH] ARM: dts: stm32: add Hardware debug port (HDP) on stm32mp157c-dk2 board MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit On the stm32mp157fc-dk2 board, we can observe the hdp GPOVAL function on SoC pin E13 accessible on the pin 5 on the Arduino connector CN13. Add the relevant configuration but keep it disabled as it's used for debug only.
