Convert the device tree bindings for the Altera Root Port PCIe controller
from text to YAML.

Signed-off-by: Matthew Gerlach <matthew.gerlach@linux.intel.com>
---
v4:
 - reorder reg-names to match original binding
 - move reg and reg-names to top level with limits.

v3:
 - Added years to copyright
 - Correct order in file of allOf and unevaluatedProperties
 - remove items: in compatible field
 - fix reg and reg-names constraints
 - replace deprecated pci-bus.yaml with pci-host-bridge.yaml
 - fix entries in ranges property
 - remove device_type from required

v2:
 - Move allOf: to bottom of file, just like example-schema is showing
 - add constraint for reg and reg-names
 - remove unneeded device_type
 - drop #address-cells and #size-cells
 - change minItems to maxItems for interrupts:
 - change msi-parent to just "msi-parent: true"
 - cleaned up required:
 - make subject consistent with other commits coverting to YAML

-Required properties:
-- compatible :	should contain "altr,pcie-root-port-1.0" or "altr,pcie-root-port-2.0"
-- reg:		a list of physical base address and length for TXS and CRA.
-		For "altr,pcie-root-port-2.0", additional HIP base address and length.
-- reg-names:	must include the following entries:
-		"Txs": TX slave port region

-- interrupts:	specifies the interrupt source of the parent interrupt

-- #interrupt-cells:	set to <1>
-- ranges:	describes the translation of addresses for root ports and

What happened to this? It is clearly needed since the interrupt-map 
below points back to this node. Note that that didn't work at one point 
in time, but I think we fixed it.

It doesn't seem you are testing the binding against an actual DT. 
Please do that.

I think the DTs I was using test were created during the point in time 
when this did not work. The interrupt-controller boolean and 
#interrupt-cells property were in a sub node, and the interrupt-map 
pointed to the sub-node. Keeping everything in the base node maintains 
compatiblity. I will fix this for v5.

I need to fix the DTs I'm using for test :)

Thanks for the feedback,

When I added the interrupt-controller boolean back to the base node, 
pcie_0, and fixed the interrupt-map in the yaml example to point to 
pcie_0, I get what appears to be the warning below from the 
dt_binding_check below. The exit code is still 0:

make dt_binding_check DT_SCHEMA_FILES=altr,pcie-root-port.yaml
   SCHEMA  Documentation/devicetree/bindings/processed-schema.json
   CHKDT   Documentation/devicetree/bindings
   LINT    Documentation/devicetree/bindings
   DTEX

   DTC_CHK 
Documentation/devicetree/bindings/pci/altr,pcie-root-port.example.dtb
/home/mgerlach/git/linux-next/Documentation/devicetree/bindings/pci/altr,pcie-root-port.example.dtb: 
pcie@c00000000: interrupt-map: [[0, 0, 0, 1, 2, 1, 0, 0, 0], [2, 2, 2, 0, 
0, 0, 3, 2, 3], [0, 0, 0, 4, 2, 4]] is too short

The warning from checking a DTS with the binding provides a little more 
information, but the warning puzzles me because of the 9 entry lists:

make CHECK_DTBS=y DT_SCHEMA_FILES=altr,pcie-root-port.yaml 
intel/socfpga_agilex7f_socdk_pcie_root_port.dtb
   DTC_CHK

0, 0, 0, 3, 21, 3], [0, 0, 0, 4, 21, 4]] is too short

The resulting device tree and driver code work as expected, but the 
warning is concerning. I can make the warning go away by putting 
interrupt-controller and #interrupt-cells in a subnode and make 
interrupt-map point to the subnode, but this requires changing the 
accepted driver code.

Any suggestions on how to proceed? I think changing the existing driver 
seems wrong.

Thanks,
Matthew Gerlach
