Subject: [PATCH v3 8/9] ARM: sun8i: Add PRCM clock and reset controller nodes to the DTSI
Date: Thu, 3 Jul 2014 22:55:48 +0800 [thread overview]
Message-ID: <1404399349-20237-9-git-send-email-wens@csie.org> (raw)
In-Reply-To: <1404399349-20237-1-git-send-email-wens-jdAy2FN1RRM@public.gmane.org>
With sun8i PRCM support available, we can add the PRCM clock and
reset controller nodes to the DTSI. Also update R_UART's clock
phandle and add it's reset control phandle.
