4 Subject: [PATCH] BCM270X_DT: Update UART0 clock-frequency
6 The Raspberry Pi firmware now sets the UART0 clock frequency to
7 48MHz (was 3MHz), to allow for baudrates up to 3MHz. This value
8 is overwritten by the firmware, but alternative loaders such
9 as U-Boot ignore the firmware-provided DTB. And besides, the
10 default ought to be correct.
