[PATCH v2 0/9] Add STM32MP25 SPI NOR support

[patrice.chotard at foss.st.com]

From: Patrice Chotard <patrice.chotard at foss.st.com>

This series adds SPI NOR support for STM32MP25 SoCs from STMicroelectronics,
for that it adds support for:
  - Octo Memory Manager driver.
  - Octo SPI driver.
  - yaml schema for Octo Memory Manager and Octo SPI drivers.

The device tree files adds Octo Memory Manager and associated Octo SPI instances
in stm32mp251.dtsi and adds SPI NOR support in stm32mp257f-ev1 board.

Signed-off-by: Patrice Chotard <patrice.chotard at foss.st.com>

Changes in v2:
  - Move STM32 Octo Memory Manager controller driver and bindings from
    misc to memory-controllers.
  - Update STM32 OSPI controller bindings.
  - Update STM32 Octo Memory Manager controller bindings.
  - Update STM32 Octo Memory Manager driver to match bindings update.
  - Update DT to match bindings update.
