Add the definition for ICL power wells and their mapping to power domains. On ICL there are 3 power well control registers, we'll select the correct one based on higher bits of the power well ID. The offset for the control and status flags within this register is based on the lower bits of the ID as on older platforms. As the DC state programming is also the same as on old platforms we can reuse the corresponding helpers. For this we mark here the DC-off power well as shared among multiple platforms. Other than the above the delta between old platforms and ICL: - Pipe C has its own power well, so we can save some additional power in the pipe A+B and (non-eDP) pipe A configurations. - Power wells for port E/F DDI/AUX IO and Thunderbolt 1-4 AUX IO v2: - Rebase on drm-tip after prep patch for this was merged there as requested by Paulo. - Actually add the new AUX and DDI power well control regs (Rakshmi) v3: - Fix power well register names in code comments - Add TBT AUX->power well 3 dependency v4: - Rebase v5: - Detach AUX power wells from the INIT power domain. These power wells can only be enabled in a TC/TBT connected state and otherwise not needed during driver initialization. v6: - Use _MMIO_PORT(...) instead _MMIO(_PICK(...)) (Paulo) Fix checkpatch warnings.
