From: Martin Blumenstingl <martin.blumenstingl@googlemail.com> stable inclusion from stable-v5.10.101 commit 74cd5cb2190f1cb424d07be608149833eed27ebf bugzilla: https://gitee.com/openeuler/kernel/issues/I5669Z Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- [ Upstream commit 3375aa77135f6aeb1107ed839a2050a4118444bc ] The dt-bindings for the UART controller only allow the following values for Meson8 SoCs: - "amlogic,meson8b-uart", "amlogic,meson-ao-uart" - "amlogic,meson8b-uart" Use the correct fallback compatible string "amlogic,meson-ao-uart" for AO UART. Drop the "amlogic,meson-uart" compatible string from the EE domain UART controllers. Also update the order of the clocks to match the order defined in the yaml bindings.
