Subject: [PATCH 0/3] mailbox: zynqmp: Enable Bufferless IPIs for Versal based SOCs
Date: Thu, 14 Dec 2023 13:13:51 -0800	[thread overview]
Message-ID: <20231214211354.348294-1-ben.levinsky@amd.com> (raw)

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@amd.com/T/

  mailbox: zynqmp: Move buffered IPI setup to of_match selected routine
  mailbox: zynqmp: Enable Bufferless IPI usage on Versal-based SOC's
