Subject: [RFC 04/19] clk: imx6q: Do not reparent uninitialized IMX6QDL_CLK_PERIPH2 clock
Date: Fri, 22 Mar 2019 15:37:03 +0000	[thread overview]
Message-ID: <1553269010-15591-5-git-send-email-abel.vesa@nxp.com> (raw)
In-Reply-To: <1553269010-15591-1-git-send-email-abel.vesa@nxp.com>

The clock is registered later than these two re-parentings.
