From b6a6238f0455db4ad9f447a4424cb5f56e47cd60 Mon Sep 17 00:00:00 2001 From: Lukasz Majewski Date: Wed, 9 Jan 2019 23:05:02 +0100 Subject: [PATCH] Revert "dm: pinctrl: Prevent (re-)configuring pins when already done before relocation" This reverts commit a7f4b4b344396590845e6552c82829ef68ef9f89. As reported by Alex Kiernan the above optimization introduces a regression in the below use case where: 1. Device has defined 'u-boot,dm-spl' property (@ eMMC DTS node) 2. The device downloads its MLO/SPL via UART (not eMMC - the eMMC pinmux pins are NOT probed/configured in MLO/SPL). 3. The loaded via UART MLO/SPL wants to load Linux from eMMC. In this case the DM core and pinctrl uclass checks 'u-boot,dm-spl' and don't configure pins (as it thinks that those were initialized in MLO/SPL). As we are very close to release - please revert this commit.
