[PATCH 0/3] mailbox: zynqmp: Enable Bufferless IPIs for Versal based SOCs
From: Ben Levinsky
Date: Thu Dec 14 2023 - 16:14:42 EST
For Xilinx-AMD Versal and Versal NET SOC's there exist also
inter-processor-interrupts (IPIs) without IPI Message Buffers. For these
enable use of IPI Mailbox driver for send/receive as well.
This is enabled with new compatible string: "xlnx,versal-ipi-mailbox"
Original, buffered usage for ZynqMP based SOC is still supported.
Note that the linked patch provides corresponding bindings.
Depends on: https://lore.kernel.org/all/20231214054224.957336-3-tanmay.shah@xxxxxxx/T/
