Subject: [PATCH] i.MX: ecspi: Enable imx->clk as a part of initialization
Date: Wed, 10 Jan 2018 08:31:59 -0800	[thread overview]
Message-ID: <20180110163159.16379-1-andrew.smirnov@gmail.com> (raw)

Some SoCs (e. g. i.MX7) do not enable this clock by default, so add
code to take care of that in the driver.
