Subject: [PATCH] ASoC: SOF: add _D3_PERSISTENT flag to fw_ready message
Mime-version: 1.0
Content-type: text/plain; charset=UTF-8
Content-transfer-encoding: 8bit
Git-commit: 1dafede34dda19fc2878724145dc16c0b51dc174
Patch-mainline: v5.18-rc1
References: jsc#PED-850
Add a bit definition to the fw_ready message, to denote if the FW
supports the IMR (Isolated Memory Region) restoring feature.
If the bit is set, the driver can skip downloading the firmware again
during system resume or runtime resume.
Bump the ABI version to 3.19 to make it aligned with FW side.
