We used to use a fixed rate clock for the UARTs. Now that we have clock support we can associate the correct clocks to the UARTs and drop the 26MHz fixed rate UART clock. Signed-off-by: Erin Lo <erin.lo@xxxxxxxxxxxx> --- This patch dependents on "Add clock support for Mediatek MT2701"[1]. If we have clock support, we must associate the correct clocks to the UARTs. Otherwise it will cause booting issue. Please also accept this patch together with [1].
