From e1ec8f588492e1e848a66b2ad854ae53121ac416 Mon Sep 17 00:00:00 2001 From: Celina Sophie Kalus Date: Fri, 1 Mar 2024 11:10:42 +0100 Subject: [PATCH] dts: bindings: mbox: Add STM32 HSEM MBOX driver Add a device tree binding for the new driver. Since there already exists an IPM driver using the unsharable hardware semaphore interrupt, the new driver is not added to any boards or SOCs per default to avoid compatibility problems. See #37300 for the IPM driver.
