Subject: [PATCH V5 4/9] pinctrl: imx8mn: Support building as module
Date:   Thu, 11 Jun 2020 19:34:50 +0800
Message-Id: <1591875295-19427-5-git-send-email-Anson.Huang@nxp.com>
In-Reply-To: <1591875295-19427-1-git-send-email-Anson.Huang@nxp.com>
References: <1591875295-19427-1-git-send-email-Anson.Huang@nxp.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Change configuration to "tristate", add module device table,
author, description and license to support building i.MX8MN
pinctrl driver as module.

Changes since V4:
	- remove unnecessary change of replacing arch_initcall() with module_platform_driver();
	- add module author and description;
	- add more details to commit message.
