[PATCH v4 2/8] ARM: dts: Specify clocks for UARTs on bcm11351

From: Tim Kryger <hidden>
Date: 2013-12-05 19:30:53
Also in: linux-devicetree, linux-mmc, lkml
Subsystem: the rest · Maintainer: Linus Torvalds

The frequency property in "snps,dw-apb-uart" entries are no longer
required if the rate of the external clock can be determined using the
clk api (see e302cd9 serial: 8250_dw: add support for clk api).

This patch replaces the frequency property in the UART nodes of
bcm11351.dtsi with references to the relevant clocks following the
common clock binding.
