[PATCH v3 0/7] Fix RISC-V/PCI dt-schema issues with dt-schema v2022.08

[Conor Dooley]

From: Conor Dooley <conor.dooley@microchip.com>

Hey all,

Got a few fixes for PCI dt-bindings that I noticed after upgrading my
dt-schema to v2022.08.

Since all the dts patches are for "my" boards, I'll take them once the
bindings are approved. I added a pair of other dts changes to the series,
mostly for my own benefit in tracking what I need to apply that were
previously at [0] & [1].

Thanks,
Conor.

1 - https://lore.kernel.org/all/20220811204024.182453-1-mail@conchuod.ie/

Changes since v2:
- fu740: make clock-names required
- mchp: add regex to clock names
- mchp: add a new patch adding dma-ranges as optional

Changes since v1:
- fu740: rewrite commit message
- mchp: rework clock-names as per rob's suggestion on IRC
- mchp: drop the "legacy" from the node name
- mchp: renemove the address translation property
- mchp: change the child node name in the dts rather than the binding

[PATCH v3 1/7] dt-bindings: PCI: fu740-pci: fix missing clock-names

[Conor Dooley]

From: Conor Dooley <conor.dooley@microchip.com>

The commit b92225b034c0 ("dt-bindings: PCI: designware: Fix
'unevaluatedProperties' warnings") removed the clock-names property as
a requirement and from the example as it triggered unevaluatedProperty
warnings. dtbs_check was not able to pick up on this at the time, but
now can:

arch/riscv/boot/dts/sifive/hifive-unmatched-a00.dtb: pcie@e00000000: Unevaluated properties are not allowed ('clock-names' was unexpected)
        From schema: linux/Documentation/devicetree/bindings/pci/sifive,fu740-pcie.yaml

The property was already in use by the FU740 DTS and the clock must be
enabled. The Linux and FreeBSD drivers require the property to enable
the clocks correctly Re-add the property and its "clocks" dependency,
while making it required.

It was my expectation anyway that you would take the binding patches.
They're marked "not applicable" in the dt patchwork so appear that
Rob does not want to take them. Won't speak for him though!

I intend to take the dts part of the series through riscv's fixes as
the series will get the arch down to zero dtbs_check warnings. Could
you take the patches through the PCI fixes tree please?

Thanks,
Conor.

[PATCH v3 2/7] dt-bindings: PCI: microchip,pcie-host: fix missing clocks properties

[Conor Dooley]

From: Conor Dooley <conor.dooley@microchip.com>

Recent versions of dt-schema warn about unevaluatedProperties:
arch/riscv/boot/dts/microchip/mpfs-icicle-kit.dtb: pcie@2000000000: Unevaluated properties are not allowed ('clock-names', 'clocks', 'legacy-interrupt-controller', 'microchip,axi-m-atr0' were unexpected)
        From schema: Documentation/devicetree/bindings/pci/microchip,pcie-host.yaml

The clocks are required to enable interfaces between the FPGA fabric
and the core complex, so add them to the binding.

[PATCH v3 6/7] riscv: dts: microchip: mpfs: remove bogus card-detect-delay

[Conor Dooley]

From: Conor Dooley <conor.dooley@microchip.com>

Recent versions of dt-schema warn about a previously undetected
undocumented property:
arch/riscv/boot/dts/microchip/mpfs-icicle-kit.dtb: mmc@20008000: Unevaluated properties are not allowed ('card-detect-delay' was unexpected)
        From schema: Documentation/devicetree/bindings/mmc/cdns,sdhci.yaml

There are no GPIOs connected to MSSIO6B4 pin K3 so adding the common
cd-debounce-delay-ms property makes no sense. The Cadence IP has a
register that sets the card detect delay as "DP * tclk". On MPFS, this
clock frequency is not configurable (it must be 200 MHz) & the FPGA
comes out of reset with this register already set.

[PATCH v3 7/7] riscv: dts: microchip: mpfs: remove pci axi address translation property

[Conor Dooley]

From: Conor Dooley <conor.dooley@microchip.com>

An AXI master address translation table property was inadvertently
added to the device tree & this was not caught by dtbs_check at the
time. Remove the property - it should not be in mpfs.dtsi anyway as
it would be more suitable in -fabric.dtsi nor does it actually apply
to the version of the reference design we are using for upstream.

Applied to dt-fixes, RISC-V should be back to 0 warnings in the next
