+Subject: [PATCH 1/3] ARM: stm32: Supply a DTS file for the STM32F469 Discovery
+ board
+
+It's pretty similar to the STM32F429, but there are some
+subtle changes required to boot successfully.

At the time of submission, the Mainline kernel does not currently support the STM32f469. This patch adds a new DTS file which contains some critical information to ensure a clean, visible boot.
