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