Merge tag 'rproc-v6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux
Pull remoteproc updates from Bjorn Andersson: "Support for controlling the second core in Mediatek's SCP dual-core setup is introduced. Support for audio, compute and modem DSPs on Qualcomm SM6375, and the audio DSP in SC7180 are introduced. The peripheral NoC clock is dropped from MSM8996 modem DSP, as this is handled through the interconnect provider. In the zynqmp driver the setup for TCM memory, and device address translation thereof, when operating in lockstep mode is corrected. A few bug fixes and cleanups are introduces across the ST and STM32 remoteproc drivers" * tag 'rproc-v6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux: (28 commits) remoteproc: st: Fix sometimes uninitialized ret in st_rproc_probe() remoteproc: st: Use device_get_match_data() remoteproc: zynqmp: Change tcm address translation method remoteproc: mediatek: Refactor single core check and fix retrocompatibility remoteproc: qcom: q6v5-mss: Remove PNoC clock from 8996 MSS dt-bindings: remoteproc: qcom,msm8996-mss-pil: Remove PNoC clock dt-bindings: remoteproc: qcom,adsp: Remove AGGRE2 clock remoteproc: qcom: pas: Add SM6375 MPSS remoteproc: qcom: pas: Add SM6375 ADSP & CDSP dt-bindings: remoteproc: qcom,sm6375-pas: Document remoteprocs dt-bindings: remoteproc: pru: Add Interrupt property remoteproc: qcom: pas: Add sc7180 adsp dt-bindings: remoteproc: qcom: sc7180-pas: Add ADSP compatible arm64: dts: mediatek: Update the node name of SCP rpmsg subnode remoteproc: zynqmp: fix TCM carveouts in lockstep mode remoteproc: mediatek: Refine ipi handler error message remoteproc: mediatek: Report watchdog crash to all cores remoteproc: mediatek: Handle MT8195 SCP core 1 watchdog timeout remoteproc: mediatek: Setup MT8195 SCP core 1 SRAM offset remoteproc: mediatek: Remove dependency of MT8195 SCP L2TCM power control on dual-core SCP ...
