From f831584128ac2a36fb4fa62fe106793d08c2dbf1 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Wed, 2 Sep 2026 14:39:50 +0200 Subject: [PATCH] soc: st: Add STM32MP2 SYSCFG driver Add trivial SYSCFG driver for ST STM32MP25xx, which binds drivers to its subnodes. This is currently used to bind USB PHY drivers to subnodes described in the SYSCFG DT node.
