[Intel-gfx] [PATCH 03/21] drm/i915/adl_s: Add ADL-S platform info and PCI ids

Aditya Swarup
2020-11-17T18:50:52Z

From: Caz Yokoyama <caz.yokoyama@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)

Bspec: 53597
Bspec: 53648
Bspec: 53655
Bspec: 48028
Bspec: 53650
BSpec: 50422
