Subject: [PATCH v2 2/2] clk: imx: imx8m: use devm_of_clk_add_hw_provider()
Date: Tue, 28 Jul 2020 17:03:19 +0800
Message-ID: <1595926999-14934-2-git-send-email-peng.fan@nxp.com> (raw)
In-Reply-To: <1595926999-14934-1-git-send-email-peng.fan@nxp.com>

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

Use devm_of_clk_add_hw_provider() to simplify code.
To i.MX8MP, also add err handling.
