When DT overlay is applied at run time compatible string or model AFAIK is not updated. But when fdtoverlay tool is used it actually creates full description for used SOM and carrier card(CC). That's why there is no reason to use generic SOM name and its compatible strings because they are not properly reflected in newly created DT. Composing dt overlays together was introduced by commit 7a4c31ee ("arm64: zynqmp: Add support for Xilinx Kria SOM board") and later renamed by commit 45fe0dc4 ("arm64: xilinx: Use zynqmp prefix for SOM dt overlays"). DTB selection is done prior booting OS that's why there is no need to do run time composition for SOM and CC combination. And user space can use compatible string and all listed revisions to figured it out which SOM and CC combinations OS is running at. Reviewed-by:

Revision 2 is SW compatible with revision 1 but it is necessary to reflect it in model and compatible properties which are parsed by user space. Rev 2 has improved a power on boot reset and MIO34 shutdown glich improvement done via an additional filter in the GreenPak chip. Reviewed-by:

dwc3-xilinx.yaml defines 2 clocks which are not defined that's why define them (bus_early clock is moved to bus_clk in glue logic). With also describing kv260 assigned clock rates with assigned clocks. Also add missing status property to standard dwc3 core.

SMMU is disabled by default and not all masters can be enabled at the same time because of limited number of entries. That's why comment all iommu properties but keep them for reference in DT. In XEN case they should be added back and Xen should have SMMU enabled by default. Also add IDs for DP and DPDMA.

Anything ending with gpio/gpios is taken as gpio phande/description which is reported as the issue coming from gpio-consumer.yaml schema. That's why rename the gpio suffix to gpio-grp to avoid name collision. Link: https://lore.kernel.org/r/94f633e26b7b16cabddb8c7210c2e79208c364da.1704728353.git.michal.simek@amd.comSigned-off-by:

gpio38 is used in SOM's kv260 to reset the Ethernet PHY. At present, HW reset is not working properly as Tri-state is enabled for MIO38, causing inappropriate PHY register reads. Disabled Tri-state for MIO38 to make HW reset work.

Remove incorrect comment about required nodes by spec. In past gem3 was the part of SOM specification but it has been revisit by introducting KR260. Link: https://lore.kernel.org/r/0bd166345ce78097a1ff8d4307545f5026c92267.1704728353.git.michal.simek@amd.comSigned-off-by:

Add u-boot options node with details about bootscr-address. c&p description from dtschema/schemas/options/u-boot.yaml: "Holds the full address of the boot script file. It helps in making automated flow easier by fetching the 64bit address directly from DT. Value should be automatically copied to the U-Boot 'scriptaddr' variable. When it is defined, bootscr-ram-offset property should be ignored. Actually only one of them should be present in the DT." Address is generic for all zynqmp boards because all of them have DDR starting from 0. Custom boards should revisit the location and aligned it based on their needs.

All si570 mgt chips have factory default 156.25MHz but DT changed it to 148.5MHz. After tracking it is pretty much c&p fault taken from Zynq zc702/zc706 boards where 148.5MHz was setup as default because it was requirement for AD7511 chip available on these boards. ZynqMP board don't contain this chip that's why factory default frequency can be used.

Now that the zynqmp pinctrl driver supports the tri-state registers, make sure that the pins requiring output-enable are configured appropriately for SOMs. Without it, all tristate setting for MIOs, which are not related to SOM itself, are using default configuration which is not correct setting. It means SDs, USBs, ethernet, etc. are not working properly. In past it was fixed through calling tristate configuration via bootcmd: usb_init=mw 0xFF180208 2020 kv260_gem3=mw 0xFF18020C 0xFC0 && gpio toggle gpio@ff0a000038 && \ gpio toggle gpio@ff0a000038 Signed-off-by:
