Subject: [U-Boot] [PATCH v10 01/35] usb: sunxi: Simplify ccm reg base code
Date: Mon, 28 May 2018 16:48:12 +0530	[thread overview]
Message-ID: <20180528111846.14316-2-jagan@amarulasolutions.com> (raw)
In-Reply-To: <20180528111846.14316-1-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.
