From ab2e0f4f6cbfa8220e75a29cf80abbd8eeec7879 Mon Sep 17 00:00:00 2001 From: Alexandre Torgue Date: Tue, 3 Jun 2025 11:02:07 +0200 Subject: [PATCH] ARM: dts: stm32: fullfill diversity with OPP for STM32M15xF SOCs This commit creates new file to manage security features and supported OPP on STM32MP15xF SOCs. On STM32MP15xY, "Y" gives information: -Y = A means no cryp IP and no secure boot + A7-CPU@650MHz. -Y = C means cryp IP + optee + secure boot + A7-CPU@650MHz. -Y = D means no cryp IP and no secure boot + A7-CPU@800MHz. -Y = F means cryp IP + optee + secure boot + A7-CPU@800MHz. It fullfills the initial STM32MP15x SoC diversity introduced by commit 0eda69b6c5f9 ("ARM: dts: stm32: Manage security diversity for STM32M15x SOCs").
