   4 Subject: [PATCH 11/31] arm: dts: mt7622: force high-speed mode for uart
   5
   6 The input clock for uart is too slow (25MHz) which introduces frequent data
   7 error on both receiving and transmitting even if the baudrate is 115200.
   8
   9 Using high-speed can significantly solve this issue.
