Subject: [U-Boot] [PATCH 07/12] aspeed/ast2500: Helper function to get access to SCU
Date: Wed, 4 Jan 2017 11:46:51 -0800 [thread overview]
Message-ID: <20170104194656.124368-8-maxims@google.com> (raw)
In-Reply-To: <20170104194656.124368-1-maxims@google.com>
Helper function to get access to SCU (System Control Unit) through Clock
driver. This is similar to rockchip_get_cru function, which was used as
an example.
It will be used by other drivers to get access to SCU.
