Merge series "Add support for SOF on i.MX8M" from Daniel Baluta <daniel.baluta@oss.nxp.com>
Daniel Baluta <daniel.baluta@nxp.com>:
From: Daniel Baluta <daniel.baluta@nxp.com>
This patch series adds support for SOF on i.MX8M family. First board
from this family that has a DSP is i.MX8MP.
First 2 patches are trying to fix some compilation issues, the next two
are adding the imx8m support and the last one adds the devicetree
binding.
Changes since v2:
- add reviewed by from Rob to DT patch
- fix ownership for patch 2
Daniel Baluta (3):
ASoC: SOF: imx: Add i.MX8M HW support
ASoC: SOF: Add i.MX8MP device descriptor
dt-bindings: dsp: fsl: Add fsl,imx8mp-dsp entry
Pierre-Louis Bossart (1):
ASoC: SOF: imx: fix undefined reference issue
YueHaibing (1):
ASoC: SOF: imx8: Fix randbuild error
