Backport AXI 1-wire host driver

[Portia Stephens]

[ Impact ]

* Backport AXI 1-wire host driver.
* The driver is used to interface with FPGA IP logic.
* The driver is only loaded when device tree overlay is applied on platforms that require the driver.

[ Test Plan ]

* Xilinx will test the functionality on a KD240 with an FPGA bitstream that has the required IP logic.

[ Where problems could occur ]

* We are unable to run certification testing with the driver loaded which creates a risk of breaking the driver in the future.

[ Other info ]

* Private LP bug: https://bugs.launchpad.net/limerick/+bug/2052477

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This bug is awaiting verification that the linux-xilinx-zynqmp/5.15.0-1029.33 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-jammy-linux-xilinx-zynqmp' to 'verification-done-jammy-linux-xilinx-zynqmp'. If the problem still exists, change the tag 'verification-needed-jammy-linux-xilinx-zynqmp' to 'verification-failed-jammy-linux-xilinx-zynqmp'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

Hi @Portia

I verified the working of AXI 1-wire with the above 1029.33 kernel. Everything working as expected and all good there.

Thanks
