Subject: [PATCH v2 0/3] mailbox: zynqmp: Enable Bufferless IPIs for Versal based SOCs
Date: Thu, 11 Jan 2024 09:22:23 -0800 [thread overview]
Message-ID: <20240111172226.1816105-1-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/
v2:
- formatting in 2/3 patch
- remove extra handling in 3/3 versal_ipi_setup()
Ben Levinsky (3):
mailbox: zynqmp: Move of_match structure closer to usage
mailbox: zynqmp: Move buffered IPI setup to of_match selected routine
mailbox: zynqmp: Enable Bufferless IPI usage on Versal-based SOC's
