Subject: [PATCH V3 1/7] firmware: imx: Add stubs for !CONFIG_IMX_SCU case
Date:   Mon,  9 Mar 2020 08:38:14 +0800
Message-Id: <1583714300-19085-1-git-send-email-Anson.Huang@nxp.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Add stubs for those i.MX SCU APIs to make those modules depending
on IMX_SCU can pass build when COMPILE_TEST is enabled.

Signed-off-by: Anson Huang <Anson.Huang@nxp.com>

Changes since V2:
	- return error for stubs.
