Subject: [PATCH] MLK-15960-2: ASoC: fsl_sai: refine the pm runtime function
|
|
|
|
In imx8qm/imx8qxp, the power domain of IP is enabled when
|
|
pm_runtime_get_sync() is called, and disabled when pm_runtime
|
|
_put_sync() is called. when power domain is disabled, the value
|
|
of registers will lost, so we need to use the regcache_sync()
|
|
to restore the registers in fsl_sai_runtime_resume.
