6f2e0ad194 ARM: dts: stm32: add cpufreq support on stm32mp15x
This commit adds cpufreq support on stm32mp15x SOC. STM32 cpufreq uses
operating points V2 bindings (no legacy). Nvmem cells have to be used to
know the chip version and then which OPPs are available. Note that STM32
cpufreq driver is mainly based on "cpufreq-dt" driver.

9e69696506 dts: ARM: stm32mp15: add OP-TEE node in u-boot DTSI
Add OP-TEE firmware node in stm32mp15 U-Boot DTSI. This node is
needed since commit [1] that changed U-Boot/stm32mp15 to detect
OP-TEE availability by probing the resource instead of relying on
U-Boot configuration. The software sequence implemented by [1] is
fine but U-Boot DTS/DTSI files were not updated accordingly since,
hence OP-TEE presence is never detected by U-Boot, preventing Linux
kernel from using OP-TEE resources.

For consistency and to synchronize stm32mp15 DTSI files (excluding
U-Boot specific DTSI files) with the Linux kernel ones, this change
also moves the OP-TEE reserved memory nodes from board generic DTSI
files to U-Boot specific board DTSI files.

4a1b975dac board: stm32mp1: reserve memory for OP-TEE in device tree
Add reserve memory for OP-TEE in U-Boot and in kernel device tree:
- no more reduce the DDR size in "memory" node:
  CONFIG_SYS_MEM_TOP_HIDE is no more used
- U-Boot device-tree defines the needed "reserved-memory" for OP-TEE
  and U-Boot should not use this reserved memory: board_get_usable_ram_top
  use lmb lib to found the first free region, the not reserved
  memory, enough to relocate U-Boot: the needed size of U-Boot
  is estimated with gd->mon_len + CONFIG_SYS_MALLOC_LEN.
- the optee node ("optee@...": firmware with compatible "linaro,optee-tz")
  and the associated "reserved-memory" are deactivated in kernel device
  tree when OP-TEE is not detected by U-Boot to prevent kernel issue
  (memory is reserved but not used, optee driver probe failed).

1a4f57c895 ARM: dts: stm32mp1: DT alignment with Linux 5.6-rc1
This commit manages diversity for STM32M15x SOCs with:
- dedicated files to support all STM32MP15 SOCs family.
  The differences between those SOCs are:
  -STM32MP151 [1]: common file.
  -STM32MP153 [2]: STM32MP151 + CANs + a second CortexA7-CPU.
  -STM32MP157 [3]: STM32MP153 + DSI + GPU.
- new files to manage security diversity on STM32MP15x SOCs.
  On STM32MP15xY, "Y" gives information:
  -Y = A means no cryp IP and no secure boot.
  -Y = C means cryp IP + secure boot.
- stm32mp157 pinctrl files to better manage package diversity.
