From 0441b48570697195b924d83c0fd0dcb9f35e1865 Mon Sep 17 00:00:00 2001 From: Jagan Teki Date: Tue, 16 Mar 2021 21:52:07 +0530 Subject: [PATCH] board: stm32: Add Engicam MicroGEA STM32MP1 MicroDev 2.0 7" OF 7" OF is a capacitive touch 7" Open Frame panel solutions with - 7" AUO B101AW03 LVDS panel - EDT, FT5526 Touch MicroGEA STM32MP1 is a STM32MP157A based Micro SoM. MicroDev 2.0 is a general purpose miniature carrier board with CAN, LTE and LVDS panel interfaces. MicroGEA STM32MP1 needs to mount on top of MicroDev 2.0 board with pluged 7" OF for creating complete MicroGEA STM32MP1 MicroDev 2.0 7" Open Frame Solution board. Linux dts commit details: commit <1d278204cbaa> ("ARM: dts: stm32: Add Engicam MicroGEA STM32MP1 MicroDev 2.0 7" OF") Add support for it.
