Subject: [PATCH] arm/mach-pxa: add CCCR bits definitions
Date: Thu, 26 Jan 2012 20:55:27 +0100 [thread overview]
Message-ID: <1327607728-2788-4-git-send-email-robert.jarzmik@free.fr> (raw)
In-Reply-To: <1327607728-2788-1-git-send-email-robert.jarzmik@free.fr>
Add CCCR bits definition for PXA SoC, so that the bootloader
can setup a stable core clock frequency, which is not the
initial reset clock, as required by Intel's PXA27x Processor
family developer's guide, chapter 3.5.5, table 3.7 (clock
frequencies).
