[PATCH v2 0/2] Add support for Agilex5 SoCFPGA 013b board

[PATCH v2 0/2] Add support for Agilex5 SoCFPGA 013b board

[niravkumarlaxmidas.rabara]

From: Niravkumar L Rabara <niravkumarlaxmidas.rabara@altera.com>

Agilex5 SoCFPGA 013b is a low cost and small form factor development kit
compared to other Agilex5 development kits.
It Supports both tabletop and PCIe add-in card operation. It features
expansion headers for Raspberry Pi 4/5 HATs and Digilent Pmod modules,
enabling integration with popular ecosystems.

https://www.altera.com/products/devkit/a1jui0000057q9nmau/agilex-5-fpga-e-series-013b-development-kit

* Patch 1 - Add compatible string for the new 013b board.
* Patch 2 - Add device tree for 013b board.

Note:
The patch 2 depends on the series: "Add iommu supports"
https://lore.kernel.org/all/cover.1760486497.git.khairul.anuar.romli@altera.com/

Patch series "Add iommu supports" is applied to socfpga maintainer's tree
https://git.kernel.org/pub/scm/linux/kernel/git/dinguyen/linux.git/log/?h=socfpga_dts_for_v6.19

Changelog:
v1->v2:
* No change in DT bindings patch, retains Acked-by
* Add more description about 013b board in cover letter.
* Drop Agilex5 from commit header in DTS patch.
* Add more details about 013b board in commit message of DTS patch.
