> Subject: [PATCH v3 0/6] Configure imx8mp dsp node for rproc usage > > DSP found in i.MX8MP SOC can be used by multiple frameworks in > order to enable various applications: > - rproc/rpmsg framework, used to load for example Zephyr > samples > - Sound Open Firmware, used to enable various audio processing > pipelines. > > Current dsp node was configured with SOF in mind but it doesn't work > well with imx8mp-evk dts. SOF controls audio IPs from firmware side > while imx8mp-evk preffers to control audio IPs from Linux side. > > So, configure 'dsp' node to be used with rproc scenario and later will > add a separate dts or an overlay to configure the node for SOF. > > This patch series configures and enables dsp node to be used with > rproc. > > Changes since v1: > - document syscon compatible as pointed by Peng Fan > - do not disable dsp_reserved node in the dtsi file as pointed > by Ahmad Fatoum. > Changes since v2: > - Fix dts example in patch 4/6 > - Frank Li commented that we should handle the reset using the > reset > interface. I have two objections on this: we are using some bits > from audiomix > for reset together some other bits from DAP region.
