From 283f1b9a0401859c53fdd6483ab66f1c4fadaea5 Mon Sep 17 00:00:00 2001 From: Dong Aisheng Date: Fri, 2 Jul 2021 16:54:38 +0800 Subject: clk: imx6q: fix uart earlycon unwork The earlycon depends on the bootloader setup UART clocks being retained. There're actually two uart clocks (ipg, per) on MX6QDL, but the 'Fixes' commit change to register only one which means another clock may be disabled during booting phase and result in the earlycon unwork.
