[PATCH 0/8] Support STM32h747i-disco board

[Dario Binacchi]

The series adds support for STM32h747i-disco board

The board includes an STM32H747XI SoC with the following resources:
 - 2 Mbytes Flash
 - 1 Mbyte SRAM
 - LCD-TFT controller
 - MIPI-DSI interface
 - FD-CAN
 - USB 2.0 high-speed/full-speed
 - Ethernet MAC
 - camera interface

[PATCH 4/8] clk: stm32h7: rename USART{7,8}_CK to UART{7,8}_CK

[Dario Binacchi]

As stated in the reference manual RM0433, the STM32H743 MCU has
USART1/2/3/6, UART4/5/7/8, and LPUART1. The patches make all the clock
macros for the serial ports consistent with the documentation.

dt-bindings subject prefix

Please use subject prefixes matching the subsystem. You can get them for
example with 'git log --oneline -- DIRECTORY_OR_FILE' on the directory
your patch is touching. For bindings, the preferred subjects are
explained here:
