This series aims to add basic LVDS display support for STM32MP257F-EV1 board.
It introduces: - the STM32 LVDS Display Interface Transmitter driver. - a new version of the STM32 LTDC driver. - the support of "panel-lvds" compatible. It adds and enables driver support for stm32mp257f-ev1-u-boot It also brings fixes to the ofnode driver. This work is based on the Linux device-tree sent recently [1].
