From: Imre Deak <imre.d...@intel.com>
The patch adds the new power wells introduced by TGL (GEN 12) and
maps these to existing/new power domains. The changes for GEN 12 wrt
to GEN 11 are the following:
- Transcoder#EDP removed from power well#1 (Transcoder#A used in
low-power mode instead)
- Transcoder#A is now backed by power well#1 instead of power well#3
- The DDI#B/C combo PHY ports are now backed by power well#1 instead of
power well#3
- New power well#5 added for pipe#D functionality (TODO)
- 2 additional TC ports (TC#5-6) backed by power well#3, 2 port
specific IO power wells (only for the non-TBT modes) and 4 port
specific AUX power wells (2-2 for TBT vs. non-TBT modes)
- Power well#2 backs now VDSC/joining for pipe#A instead of VDSC for
eDP and MIPI DSI (TODO)
On TGL Port DDI#C changed to be a combo PHY (native DP/HDMI) and
BSpec has renamed ports DDI#D-F to TC#4-6 respectively. Thus on ICL we
have the following naming for ports:
- Combo PHYs (native DP/HDMI):
DDI#A-B
- TBT/non-TBT (TC altmode, native DP/HDMI) PHYs:
DDI#C-F
Starting from GEN 12 we have the following naming for ports:
- Combo PHYs (native DP/HDMI):
DDI#A-C
- TBT/non-TBT (TC altmode, native DP/HDMI) PHYs:
DDI TC#1-6
To save some space in the power domain enum the power domain naming in
the driver reflects the above change, that is power domains TC#1-3 are
added as aliases for DDI#D-F and new power domains are reserved for
TC#4-6.
v2 (Lucas):
- Separate out the bits and definitions for TGL from the ICL ones.
Fix use of TRANSCODER_EDP_VDSC, that is now the correct define since
we don't define TRANSCODER_A_VDSC power domain to spare a one bit in
the bitmask (suggested by Ville)
v3 (Lucas):
- Fix missing squashes on v2
- Rebase on renamed TRANSCODER_EDP_VDSC
