Subject: [PATCH 0/4] Enable DSP device for i.MX8ULP
Date: Thu, 29 Oct 2026 15:32:53 +0800 [thread overview]
Message-ID: <20261029073257.84594-1-shengjiu.wang@oss.nxp.com> (raw)
From: Shengjiu Wang <shengjiu.wang@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
