From 655af9aa9c91303b76a9565df7292bf9ec3351a1 Mon Sep 17 00:00:00 2001 From: Patrick Delaunay Date: Fri, 15 Apr 2022 15:00:43 +0200 Subject: [PATCH] ARM: stm32mp: correctly handle Silicon revision Handle correctly the silicon revision = REV_ID[15:0] of Device Version and the associated device marking, A to Z on STMicroelectronics STM32MP SOCs. This patch prepare the introduction of next STM32MP family, with STM32MP13x Rev.Z for REV_ID = 1.1.
