From: Valentin Caron <valentin.caron@foss.st.com> Add st,stm32mp25-spi compatible in dt-bindings. STM32MP25 spi is similar to the STM32H7 except for the following two points: - Burst should not be enabled with the new DMA used on STM32MP25. - STM32MP25 SPI8 has a limited feature set, it can only send words of 8 or 16 bits and with a maximum words number of 1024.
