This patch series adds support to Run/Stall DSP found on i.MX8MP via the reset controller API. Patches 1-4 apply to reset-imx8mp-audiomix (should go via reset controller tree) * refactor code, introduce active_low configuration option and then add support to Run/Stall DSP. Patch 5 applies to imx_dsp_rproc driver (should go via REMOTEPROC tree) * use reset controller API to control the DSP instead of directly touching the audiomix registers via a syscon. Using reset controller API was suggested by Frank Li and Krzysztof Kozlowski in the following discussion thread: https://patchwork.kernel.org/project/imx/patch/20241210125338.104959-6-daniel.baluta@xxxxxxx/ Daniel Baluta (5): 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 drivers/remoteproc/imx_dsp_rproc.c | 25 +++++--- drivers/remoteproc/imx_rproc.h | 2 + drivers/reset/reset-imx8mp-audiomix.c | 86 ++++++++++++++++++++------- 3 files changed, 83 insertions(+), 30 deletions(-) -- 2.25.1
