Subject: arm64: dts: mt8173: Use real clock for UARTs
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=0e84faa163c8ad42fec05d26907af8079d418bfc;p=linux-beck.git

arm64: dts: mt8173: Use real clock for UARTs

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.
