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).

792919241b ARM: dts: stm32: Reinstate card detect behavior on ST boards
The cd-gpios with (GPIO_ACTIVE_LOW | GPIO_PULL_UP) gpio is thus far
unsupported, reinstate the old cd-gpios behavior until this handling
is fully implemented. This avoid potential issue for SDCard boot:
the card detect fails with floating gpio.

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.

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.

db0cd2d3bc ARM: dts: stm32mp1: move FDCAN to PLL4_R
LTDC modifies the clock frequency to adapt it to the display. Such
frequency change is not detected by the FDCAN driver that instead
cache the value at probe and pretend to use it later.

Keep the LTDC alone on PLL4_Q by moving the FDCAN to PLL4_R.

This patch synchronizes U-boot DT with kernel one
This is based on https://patchwork.kernel.org/cover/10797115/

This patch adds initial support of STM32MP157 discovery boards:
  - Add support of stm32mp157a discovery1 board (part number: STM32MP157A-DK1).
    This board embeds a STM32MP157a SOC with AC package (TFBGA361, 148 ios)
    and 512MB of DDR3. Several connections are available on this boards:
    4*USB2.0, 1*USB2.0 typeC, SDcard, RJ45, HDMI, Arduino connector, ...

  - Add support of stm32mp157c discovery2 board (part number: STM32MP157C-DK2).
    This board is a "super-set" of stm32mp157a-dk1. A display panel (otm8009a)
    and Murata wifi/BT combo is added.

4549e789c1 SPDX: Convert all of our multiple license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have multiple licenses (in
these cases, dual license) declared in the SPDX-License-Identifier tag.
In this case we change from listing "LICENSE-A LICENSE-B" or "LICENSE-A
or LICENSE-B" or "(LICENSE-A OR LICENSE-B)" to "LICENSE-A OR LICENSE-B"
as per the Linux Kernel style document.  Note that parenthesis are
allowed so when they were used before we continue to use them.

b90f0e7c37 stm32mp1: change STGEN clock source to HSE
No more use static frequency HSI = 64MHz for STGEN clock
but HSE (with higher accurency) by default.

Need to remove CONFIG_SYS_HZ_CLOCK as arch timer frequency
is provided at boot by BootRom and cp15 cntfrq and modified
during clock tree initialization if needed.

When HSI is no more used by any device, this internal
oscillator can be switched off to reduce consumption.
