From 58662130226c82b520c0a71b110f1248521f6797 Mon Sep 17 00:00:00 2001 From: Yixun Lan Date: Thu, 11 Jan 2018 10:33:58 +0800 Subject: [PATCH] ARM64: dts: meson-axg: uart: drop legacy compatible name from EE UART When update the clock info for the UART controller in the EE domain, the driver explicitly require 'pclk' in order to work properly. With current logic of the code, the driver will go for the legacy clock probe routine if it find current compatible string match to 'amlogic,meson-uart', which result in not requesting the 'pclk' clock, thus break the driver in the end.
