Subject: [PATCH v2 1/7] ARM: dts: stm32: fullfill diversity with OPP for
 STM32M15xF SOCs

From: Alexandre Torgue <alexandre.torgue@...s.st.com>

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@...MHz.
 -Y = C means cryp IP + optee + secure boot + A7-CPU@...MHz.
 -Y = D means no cryp IP and no secure boot + A7-CPU@...MHz.
 -Y = F means cryp IP + optee + secure boot + A7-CPU@...MHz.

It fullfills the initial STM32MP15x SoC diversity introduced by
commit 0eda69b6c5f9 ("ARM: dts: stm32: Manage security diversity
for STM32M15x SOCs").

Changes in v2:
- Remove empty files (stm32mp15xa.dtsi and stm32mp15xd.dtsi)
- Drop stm32mp15xc.dtsi updates (no stm32mp15xa.dtsi inclusion nor
  license update)
- Move cryp1 node under etzpc firewall bus
