remoteproc: k3-r5: Fix crash when issuing rproc init

2026-07-10T21:46:11Z

Prevent NULL pointer dereference with lockstep mode. Since commit 21d03d60e909 ("j7200 defconfig: add rproc commands"), issuing rproc init command with cluster configured in lockstep results in a NULL pointer dereference. This is because ti_sci_proc_request() is called on both cores on the same cluster, without checking if they are populated. To fix that, only request the core being probed, as there is no need to request the other one. Moreover, the old code was requesting both cores in lockstep mode, but only releasing one: it called k3_r5f_proc_request() with ti_sci_proc_release(), instead of using k3_r5f_proc_request()/k3_r5f_proc_release() or ti_sci_proc_request()/ti_sci_proc_release(). So, replacing k3_r5f_proc_request() by ti_sci_proc_request() restores the intended behavior. Fixes: 21d03d60e909 ("j7200 defconfig: add rproc commands") Signed-off-by: Richard Genoud (TI)

remoteproc: ipu: Use dev_read_addr_x()

2026-06-09T20:53:34Z

Use dev_read_addr_x() which supports both live device tree and flat DT backends, avoiding direct dependency on devfdt_* helpers. No functional changes. Signed-off-by: Peng Fan

remoteproc: pru: Use dev_read_addr_size_index()

remoteproc: renesas: Add Renesas R-Car Gen5 remote processor driver

2026-05-05T10:53:53Z

Add R-Car Gen5 RSIP controller remoteproc driver capable of starting the SCP, Cortex-R52 and Cortex-A720 cores in Renesas R-Car R8A78000 X5H SoC. The SCP core is started by releasing the core from reset, the Cortex-R52 and Cortex-A720 are started using the SCP SCMI call. The entry point for SCP core is fixed to its STCM, entry points for Cortex-R52 and Cortex-A720 are set during rproc load. Signed-off-by: Marek Vasut

remoteproc: imx: Add i.MX95 support

2026-02-06T23:31:32Z

i.MX95 uses System Manager(sm) API to start/stop logical machine or cpu. There are two modes: M7 in a dedicated logical machine, use LMM API M7 and A55 in same logical machine, use CPU API Extend the driver to using LMM and CPU protocol to manage the M7 core: - Detect using LMM or CPU API in probe using API scmi_imx_lmm_info(). - Compare linux LM ID(got using scmi_imx_lmm_info) and M7 LM ID(the ID is fixed as 1 in SM firmware if M7 is in a separate LM), if Linux LM ID is not same as M7 LM ID(linux and M7 in same LM), use LMM protocol to start/stop. Whether using CPU or LMM protocol to start/stop, the M7 status detection could use CPU protocol to detect started or not. So in imx_rproc_is_running, use scmi_imx_cpu_started to check the status of M7. - For above case (2), Use scmi_imx_lmm_power_boot to detect whether the M7 LM is under control of A55 LM. - For above case , after using SCMI_IMX_LMM_POWER_ON to check permission, scmi_imx_lmm_shutdown API should be called to shutdown the M7 LM. - Add a new ops imx_rproc_ops_sm.

remoteproc: imx: Support ECC initialization
