Subject: [PATCH 11/11] arm: dts: lpc32xx: remove clock frequency property from UART device nodes
Date: Fri, 20 Nov 2015 03:05:11 +0200 [thread overview]
Message-ID: <1447981511-29653-12-git-send-email-vz@mleia.com> (raw)
In-Reply-To: <1447981511-29653-1-git-send-email-vz-ChpfBGZJDbMAvxtiuMwx3w@public.gmane.org>
If clock-frequency property is given, then it substitutes calculation
of supplying clock frequency from parent clock, this may break UART,
if parent clock is given and managed by common clock framework.
