The J721E Main NavSS block contains a Mailbox IP instance with multiple clusters. Each cluster is equivalent to an Mailbox IP instance on OMAP platforms. Add all the Mailbox clusters as their own nodes under the MAIN NavSS cbass_main_navss interconnect node instead of creating an almost empty parent node for the new K3 mailbox IP and the clusters as its child nodes. All these nodes are enabled by default in the base dtsi file, but any cluster that does not define any child sub-mailbox nodes should be disabled in the corresponding board dts files. NOTE: The NavSS only has a limited number of interrupts, so none of the interrupts generated by a Mailbox IP are added by default. Only the needed interrupts that are targeted towards the A72 GIC will have to be added later on in the board dts files alongside the corresponding sub-mailbox child nodes. Signed-off-by: Suman Anna <s-anna@ti.com> --- v2: - Add interrupt-parent property and enable all clusters by default - Patch description revised accordingly v1: https://patchwork.kernel.org/patch/11053407/ arch/arm64/boot/dts/ti/k3-j721e-main.dtsi | 108 ++++++++++++++++++++++ 1 file changed, 108 insertions(+)
