Merge tag 'rproc-v5.3' of git://github.com/andersson/remoteproc
Pull remoteproc updates from Bjorn Andersson: "This adds support for the STM32 remoteproc, additional i.MX platforms with Cortex M4 remoteprocs and Qualcomm's QCS404 Compute DSP. Also initial support for vendor specific resource table entries and support for unprocessed Qualcomm firmware files" * tag 'rproc-v5.3' of git://github.com/andersson/remoteproc: remoteproc: stm32: fix building without ARM SMCC remoteproc: qcom: q6v5-mss: Fix build error without QCOM_MDT_LOADER remoteproc: copy parent dma_pfn_offset for vdev remoteproc: qcom: q6v5-mss: Support loading non-split images soc: qcom: mdt_loader: Support loading non-split images remoteproc: stm32: add an ST stm32_rproc driver dt-bindings: remoteproc: add bindings for stm32 remote processor driver dt-bindings: stm32: add bindings for ML-AHB interconnect remoteproc: Use struct_size() helper remoteproc: add vendor resources handling remoteproc: imx: Fix typo in "failed" remoteproc: imx: Broaden the Kconfig selection logic remoteproc,rpmsg: add missing MAINTAINERS file entries remoteproc: qcom: qdsp6-adsp: Add support for QCS404 CDSP dt-bindings: remoteproc: Rename and amend Hexagon v56 binding
