[PATCH 0/6] MT8188 DT and binding fixes

[Fei Shao]

Hi all,

This series is split from a previous series[1] to focus on few fixes and
improvements around MediaTek MT8188 device tree and bindings, and also
addressed comments and carried tags from the mentioned series.

[PATCH 2/6] dt-bindings: PCI: mediatek-gen3: Allow exact number of clocks only

[Fei Shao]

In MediaTek PCIe gen3 bindings, "clocks" accepts a range of 1-6 clocks
across all SoCs. But in practice, each SoC requires a particular number
of clocks as defined in "clock-names", and the length of "clocks" and
"clock-names" can be inconsistent with current bindings.

For example:
- MT8188, MT8192 and MT8195 all require 6 clocks, while the bindings
  accept 4-6 clocks.
- MT7986 requires 4 clocks, while the bindings accept 4-6 clocks.

Update minItems and maxItems properties for individual SoCs as needed to
only accept the correct number of clocks.

Fixes: c6abd0eadec6 ("dt-bindings: PCI: mediatek-gen3: Add support for Airoha EN7581")

It looks like most changes to this file have been merged via the PCI
tree.  I don't see dependencies on this in the rest of the series, so
I'm happy to take this via PCI if it makes sense.  Or if you prefer
that this be merged with the rest of the series, that's fine and you
can add my:

Let me know if I should pick this one up.
