From: Caz Yokoyama <caz.yokoy...@intel.com>
- Add the initial platform information for Alderlake-S.
- Specify ppgtt_size value
- Add dma_mask_size
- Add ADLS REVIDs
- HW tracking(Selective Update Tracking Enable) has been
removed from ADLS. Disable PSR2 till we enable software/
manual tracking.
v2:
- Add support for different ADLS SOC steppings to select
correct GT/DISP stepping based on Bspec 53655 based on
feedback from Matt Roper.(aswarup)
v3:
- Make display/gt steppings info generic for reuse with TGL and ADLS.
- Modify the macros to reuse tgl_revids_get()
- Add HTI support to adls device info.(mdroper)
v4:
- Rebase on TGL patch for applying WAs based on stepping info from
Matt Roper's feedback.(aswarup)
v5:
- Replace macros with PCI IDs in revid to stepping table.
