[PATCH 0/4] video: add STM32F429-DISCO video pipeline support

[Ahmad Fatoum]

The STM32F429-DISCO has the LCD-TFT display controller connected to a
parallel panel with MIPI-DBI over SPI for panel control.

The LTDC driver was originally written for the STM32MP1, but had some
issues last time I tested it a few years ago. I debugged it into
submission on the STM32F429 now though, so it might just work on the MP1
as well.

v1 -> v2:
  - removed stray Kconfig hunk for panel support to appropriate patch
  (Sascha)
  - fixed Kconfig help text for mipi_dbi helper
