From b0c31c3e88de32687deab57434d18844a1c9c145 Mon Sep 17 00:00:00 2001 From: Alexander Stein Date: Wed, 24 Nov 2021 08:31:09 +0100 Subject: [PATCH] Revert "tty: serial: fsl_lpuart: drop earlycon entry for i.MX8QXP" Revert commit 17d029b384b8 ("tty: serial: fsl_lpuart: drop earlycon entry for i.MX8QXP"), because this breaks earlycon support on imx8qm/imx8qxp. While it is true that for earlycon there is no difference between i.MX8QXP and i.MX7ULP (for now at least), there are differences regarding clocks and fixups for wakeup support. For that reason it was deemed unacceptable to add the imx7ulp compatible to device tree in order to get earlycon working again.
