Subject: [U-Boot] [PATCH v4 01/34] usb: sunxi: Simplify ccm reg base code
Date: Tue,  6 Feb 2018 19:55:31 +0530	[thread overview]
Message-ID: <1517927164-18197-2-git-send-email-jagan@amarulasolutions.com> (raw)
In-Reply-To: <1517927164-18197-1-git-send-email-jagan@amarulasolutions.com>

Move struct sunxi_ccm_reg pointer to private structure
so-that accessing ccm reg base become more proper way
and avoid local initialization in each function.
