For details, please refer to the respective Technical Reference Manuals [1][2] or the cover letter from the first foundation PRUSS platform driver [3]. The sub-system is represented through multiple platform device nodes which are supported through a corresponding platform driver, like the PRUSS platform driver, PRUSS irqchip driver and a PRU remoteproc driver (recently upstreamed in 5.10, 5.11 kernels). This series adds the foundation ICSSG nodes, that can in turn be referenced and used by PRU client/application drivers. The client bindings and driver changes are currently under review [4][5], but won't affect these nodes. The ICSSG nodes for AM65x are as per the Section 6.5 of the AM65x TRM for SR2.0. There are some minor functional differences between the two IP revisions, but the dts node representation difference will only be the Tx_PRUs nodes which have to be disabled in any derivative SR1.0-based dts files. Patches are on top of 5.11-rc1 + your ti-k3-dts-next branch. Note that the interrupt nodes will generate a warning about missing '#address-cells' when compiled using W=2, but adding that currently fails the dtbs_check, so going with the dt binding compliance. regards Suman [1] AM65x TRM Rev.E: http://www.ti.com/lit/pdf/spruid7 [2] J721E TRM Rev.B: http://www.ti.com/lit/zip/spruil1 [3] https://patchwork.kernel.org/project/linux-arm-kernel/cover/1596020528-19510-1-git-send-email-grzegorz.jaszczyk@linaro.org/ [4] https://patchwork.kernel.org/project/linux-remoteproc/patch/20201216165239.2744-2-grzegorz.jaszczyk@linaro.org/ [5] https://patchwork.kernel.org/project/linux-remoteproc/patch/20201211184811.6490-2-grzegorz.jaszczyk@linaro.org/ Suman Anna (2): arm64: dts: ti: k3-am65-main: Add ICSSG nodes arm64: dts: ti: k3-j721e-main: Add ICSSG nodes arch/arm64/boot/dts/ti/k3-am65-main.dtsi | 393 ++++++++++++++++++++++ arch/arm64/boot/dts/ti/k3-j721e-main.dtsi | 262 +++++++++++++++ 2 files changed, 655 insertions(+)
