Subject: [PATCH 26/34] clk: scpi: Migrate to clk_hw based OF and registration APIs
Date: Wed, 1 Jun 2016 16:15:25 -0700 [thread overview]
Message-ID: <20160601231533.9354-27-stephen.boyd@linaro.org> (raw)
In-Reply-To: <20160601231533.9354-1-stephen.boyd@linaro.org>
Now that we have clk_hw based provider APIs to register clks, we
can get rid of struct clk pointers while registering clks in
these drivers, allowing us to move closer to a clear split of
consumer and provider clk APIs.

See commit 58657d189a2f and it's children for details on this
new registration API.
