	When CONFIG_PM_SLEEP is disabled, we get a harmless warning: drivers/remoteproc/imx_dsp_rproc.c:1145:12: error: 'imx_dsp_resume' defined but not used [-Werror=unused-function] 1145 \| static int imx_dsp_resume(struct device dev) \| ^~~~~~~~~~~~~~ drivers/remoteproc/imx_dsp_rproc.c:1110:12: error: 'imx_dsp_suspend' defined but not used [-Werror=unused-function] 1110 \| static int imx_dsp_suspend(struct device dev) \| ^~~~~~~~~~~~~~~ Mark these as __maybe_unused to get a clean build.

2021-10-12	remoteproc: imx_dsp_rproc: Add remoteproc driver for DSP on i.MX	Shengjiu Wang	1	-0/+1206
	Provide a basic driver to control DSP processor found on NXP i.MX8QM, i.MX8QXP, i.MX8MP and i.MX8ULP. Currently it is able to resolve addresses between DSP and main CPU, start and stop the processor, suspend and resume. The communication between DSP and main CPU is based on mailbox, there are three mailbox channels (tx, rx, rxdb). This driver was tested on NXP i.MX8QM, i.MX8QXP, i.MX8MP and i.MX8ULP.
