From e8e66801bd512eb1e4c14efca34b7b254ad26110 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Sat, 13 Nov 2021 03:24:44 +0100 Subject: ARM: stm32: Increase USB power-good delay on DHSOM The USB hub on STM32MP1 DHCOM boards needs to wait a bit longer until the USB Vbus is stable. Increase the USB power-good delay to 1 s. This adds default-undefined STM32MP_BOARD_EXTRA_ENV variable into stm32mp15_common.h to reduce duplication in board-specific config files adding custom environment.
