- Subject: [PATCH] BCM270X_DT: Update UART0 clock-frequency
- The Raspberry Pi firmware now sets the UART0 clock frequency to
- 48MHz (was 3MHz), to allow for baudrates up to 3MHz. This value
- is overwritten by the firmware, but alternative loaders such
- as U-Boot ignore the firmware-provided DTB. And besides, the
- default ought to be correct.
- See: https://github.com/raspberrypi/linux/issues/1732
