Subject: [PATCH 02/12] clk: fixed-rate: Convert to clk_hw based APIs
Date: Fri, 30 Aug 2019 08:09:13 -0700 [thread overview]
Message-ID: <20190830150923.259497-3-sboyd@kernel.org> (raw)
In-Reply-To: <20190830150923.259497-1-sboyd@kernel.org>
This code still uses struct clk to register clks from the probe path.
Migrate this to the clk_hw based APIs to modernize the code. Also, this
isn't a module and it can't be one because the driver is always builtin
so drop the module table.
