Subject: [PATCH v1 0/3] mediatek-gen3: Add support for MT8196/MT6991

This series adds (at least partial) support for the MediaTek MT8196
Chromebook SoC and for the MT6991 Dimensity 9400 Smartphone SoC's
PCI-Express controller.

Some strange PEXTP settings were omitted, as the intention is to find
a way to set those bits *outside* of the PCI-Express driver itself as
the downstream implementation is using ugly syscons to make the PCIe
controller driver to change bits inside of a clock controller.

In the meanwhile, this is a set of clean changes that are required for
the controller inside those SoCs in *any* case; further development
will occur, with high hopes to find a solution outside of this driver.

  PCI: mediatek-gen3: Implement sys clock ready time setting
  dt-bindings: PCI: mediatek-gen3: Add support for MT6991/MT8196
  PCI: mediatek-gen3: Add support for MediaTek MT8196 SoC
