Subject: [RESEND 01/18] clk: imx: Add imx_obtain_fixed_clock clk_hw based variant
Date: Wed, 29 May 2019 12:26:39 +0000	[thread overview]
Message-ID: <1559132773-12884-2-git-send-email-abel.vesa@nxp.com> (raw)
In-Reply-To: <1559132773-12884-1-git-send-email-abel.vesa@nxp.com>

In order to move to clk_hw based API, imx_obtain_fixed_clock_hw
is added. The end goal here is to have all the clk providers use
the clk_hw based API.
