From 1efce478669516e7a0fad7fa9943c889fcc21d2e 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.
