Subject: [U-Boot] [PATCH 3/4] arm: at91: pmc: replace the constant with a define in at91_pmc.h
Date: Thu, 13 Aug 2015 15:43:20 +0200	[thread overview]
Message-ID: <1439473401-4544-4-git-send-email-evanluijk@interact.nl> (raw)
In-Reply-To: <1439473401-4544-1-git-send-email-evanluijk@interact.nl>

To enable the clocks on the at91 boards a constant (0x4) is used.
This is replaced with a define in at91_pmc.h (1 <<  2).

Signed-off-by: Erik van Luijk <evanluijk@interact.nl>
