This patch series adds support to Run/Stall DSP found on i.MX8MP via the
reset controller API.

I've addressed all review comments from v1
(https://www.spinics.net/lists/kernel/msg5556023.html)
and because of the review I've introduced 3 new patches (1-3) in order
to support resets ids via dt-bindings from
include/dt-bindings/reset/imx8mp-reset-audiomix.h

Also picked up all R-b from Frank Li, Peng Fan and Philipp Zabel.

Patches 1,2, 4-7 - should go via reset controller tree.
Patch 8 - should go via remoteproc tree.

Later after all these patches are merged we can also merge patch 3/8
via dts tree (Shawn's tree).

Daniel Baluta (8):
dt-bindings: reset: audiomix: Add reset ids for EARC and DSP
dt-bindings: dsp: fsl,dsp: Add resets property
arm64: dts: imx8mp: Add resets to dsp node
reset: imx8mp-audiomix: Add prefix for internal macro
reset: imx8mp-audiomix: Prepare the code for more reset bits
reset: imx8mp-audiomix: Introduce active_low configuration option
reset: imx8mp-audiomix: Add support for DSP run/stall
imx_dsp_rproc: Use reset controller API to control the DSP
