0b73355ba2 ARM: dts: stm32: add reset support to uart nodes on stm32mp15x
STM32 serial IP can be reset via reset controller.
Add the support of reset to uart nodes on stm32mp15-u-boot.dtsi,
the ad-dons file for U-Boot.

This patch fix issues when previous UART configuration, for example
done in TF-A or ROM code, is not handled in U-Boot stm32 serial driver
init.

This reset property won't be not added in Linux kernel device tree
as this reset is not used in Linux STM32 serial driver.

4a87fea6de ARM: dts: stm32mp1: use OPP information for PLL1 settings in SPL
This patch allows to switch the CPU frequency to 800MHz on the
ST Microelectronics board (DK1/DK2 and EV1) or dh electronics SOM
using the STM32MP15x SOC and when it is supported by the HW
(for STM32MP15xD and STM32MP15xF).

a8c97f4a00 ARM: dts: stm32: Rework DDR DT inclusion
Adjust the DDR configuration dtsi such that they only generate the
DRAM configuration node, the DDR controller node is moved into the
stm32mp157-u-boot.dtsi itself. This permits including multiple DDR
configuration dtsi files in board DT.

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.
