From: Shengjiu Wang <shengjiu.wang at nxp.com>

The debug reset control is one of the HIFI4 DSP’s reset mechanisms used
by the debug interface; add documentation for the optional debug reset
controls and update the driver to use both the soft reset and debug reset
controller APIs (the soft reset is already documented).

A HiFi4 DSP node is added and the DSP device is enabled in the i.MX8ULP

Shengjiu Wang (4):
  dt-bindings: dsp: fsl,dsp: document debug reset control
  remoteproc: imx_dsp_rproc: Add softreset and dbgreset handling
  arm64: dts: imx8ulp: add HiFi4 DSP node
  arm64: dts: imx8ulp-evk: enable HiFi4 DSP device
