Subject: [PATCH V3 04/10] clk: imx: Support building SCU clock driver as module
Date: Mon, 29 Jun 2020 13:53:56 +0800
Message-ID: <1593410042-10598-5-git-send-email-Anson.Huang@nxp.com> (raw)
In-Reply-To: <1593410042-10598-1-git-send-email-Anson.Huang@nxp.com>

There are more and more requirements of building SoC specific drivers
as modules, add support for building SCU clock driver as module to meet
the requirement.

Signed-off-by: Anson Huang <Anson.Huang@nxp.com>
---
Changes since V2:
	- use separated line for each file which is included for build;
	- include linux/export.h where necessary.
