[PATCH v2 0/5] Add DSP node for i.MX8QXP board to be used by DSP SOF driver

[Daniel Baluta]

i.MX8QXP boards feature an Hifi4 DSP from Tensilica.

This patch series aims on adding the DT node describing the DSP,
but it also contains the Linux SOF DSP driver that will use the DT node
for easier review.

Note that we switched to the new yaml format for bindings documentation.

The DSP will run SOF Firmware [1]. Patches 1,2,3 are adding support
for Linux DSP driver are already sent for review to SOF folks [2]

[2] https://github.com/thesofproject/linux/pull/1048/commits

Changes since v1:
	- removed 'clk: imx8: Add DSP related clocks' as it was already
	  applied by Shawn
	- add patches adding support for Linux DSP driver to make things
	  clear for review
	- add maxItems property for PM in DT bindings doc
