From 70af0eca2c4a2a80a8edd6ce4c4c7a9eac038893 Mon Sep 17 00:00:00 2001 From: Phil Elwell Date: Sun, 27 Nov 2016 21:45:55 +0000 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.
