[PATCH 0/8] thunderbolt: Intel Ice Lake support

[Mika Westerberg]

Hi all,

With the exception of the first patch which is fix, this series enables
Thunderbolt on Intel Ice Lake. Biggest difference from the previous
controllers is that the Thunderbolt controller is now integrated as part of
the SoC. The firmware messages pretty much follow Titan Ridge but there are
some differences as well (such as the new RTD3 veto notification). Also Ice
Lake does not implement security levels so DMA protection is handled by IOMMU.

This is v5.4 material but I'm sending it out now because I will be on
vacation next 4 weeks mostly without internet access. When I get back I'll
gather all the comments and update the series accordingly.

Thanks!

Mika Westerberg (8):
  thunderbolt: Correct path indices for PCIe tunnel
  thunderbolt: Move NVM upgrade support flag to struct icm
  thunderbolt: Use 32-bit writes when writing ring producer/consumer
  thunderbolt: Do not fail adding switch if some port is not implemented
  thunderbolt: Hide switch attributes that are not set
  thunderbolt: Expose active parts of NVM even if upgrade is not supported
  thunderbolt: Add support for Intel Ice Lake
  ACPI / property: Add two new Thunderbolt property GUIDs to the list
