Subject: [PATCH V2 02/10] clk: imx8m: drop clk_hw_set_parent for A53
Date: Thu, 12 Mar 2020 18:19:36 +0800	[thread overview]
Message-ID: <1584008384-11578-3-git-send-email-peng.fan@nxp.com> (raw)
In-Reply-To: <1584008384-11578-1-git-send-email-peng.fan@nxp.com>

From: Peng Fan <peng.fan@nxp.com>

The parent settings have been moved to dtsi, we no need to
set parent here. And clk_hw_set_parent will trigger lockdep warning,
because this api not have prepare_lock.
