Hello all, This is the continuation of the M4F RProc support series from here[0]. I'm helping out with the upstream task for Hari and so this version(v8) is a little different than the previous(v7) postings[0]. Most notable change I've introduced being the patches factoring out common support from the current K3 R5 and DSP drivers have been dropped. I'd like to do that re-factor *after* getting this driver in shape, that way we have 3 similar drivers to factor out from vs trying to make those changes in parallel with the series adding M4 support.
Anyway, details on our M4F subsystem can be found the the AM62 TRM in the section on the same: AM62x Technical Reference Manual (SPRUIV7A – MAY 2022) https://www.ti.com/lit/pdf/SPRUIV7A Thanks, Andrew [0] https://lore.kernel.org/linux-arm-kernel/20240202175538.1705-5-hnaga...@ti.com/T/ Hari Nagalla (3): dt-bindings: remoteproc: k3-m4f: Add K3 AM64x SoCs arm64: defconfig: Enable TI K3 M4 remoteproc driver arm64: dts: ti: k3-am62: Add M4F remoteproc node Martyn Welch (1): remoteproc: k3-m4: Add a remoteproc driver for M4F subsystem .../bindings/remoteproc/ti,k3-m4f-rproc.yaml | 126 +++ arch/arm64/boot/dts/ti/k3-am62-mcu.dtsi | 12 + .../arm64/boot/dts/ti/k3-am62x-sk-common.dtsi | 18 + arch/arm64/configs/defconfig | 1 + drivers/remoteproc/Kconfig | 13 + drivers/remoteproc/Makefile | 1 + drivers/remoteproc/ti_k3_m4_remoteproc.c | 785 ++++++++++++++++++ 7 files changed, 956 insertions(+) create mode 100644 Documentation/devicetree/bindings/remoteproc/ti,k3-m4f-rproc.yaml create mode 100644 drivers/remoteproc/ti_k3_m4_remoteproc.c -- 2.39.2
