Subject: [PATCH V5 1/2] firmware: imx: add dummy functions
Date: Fri, 21 Feb 2020 10:32:18 +0800 [thread overview]
Message-ID: <1582252339-15733-2-git-send-email-peng.fan@nxp.com> (raw)
In-Reply-To: <1582252339-15733-1-git-send-email-peng.fan@nxp.com>
From: Peng Fan <peng.fan@nxp.com>
IMX_SCU_SOC could be enabled with COMPILE_TEST, however there is
no dummy functions when CONFIG_IMX_SCU not defined. Then there
will be build failure.
So add dummy functions to avoid build failure for COMPILE_TEST
