The lack of a break here wasn't for falling through to some other important code, so made me do a double take. Add a break just to make things a little less confusing. Signed-off-by:

On SKL DPLL0 is used to derive CDCLK but can also be used to drive an eDP port (as long as we don't want SSC). DPLL0 is special enough to not be handled by the shared DPLL framework (drives CDCLK, not supposed to enable the HDMI mode), So we need to compute the configuration separately from the other DPLLs. Note that we don't need to reprogram DPLL0 (which would mean bringing down CDCLK) to support the various eDP 1.3 link rates as they all share the same VCO (8100). Signed-off-by:

GEN6_GT_THREAD_STATUS_REG doesn't seem to exist on VLV. Reads just give 0x0 no matter what the state of the render and media wells. There was also some hint in the Gunit HAS that thread status not being needed on VLV, and hence dropped when bringing stuff over from the IVB design. Not really a definite comment about the specific register itself though. Also the w/a itself is no longer listed for VLV in the database. It was there some time ago in the past, but I guess someone figured out the mistake and dropped it. So let's just drop it from the code as well. Signed-off-by:

Bits [18:16] of GEN6_GT_THREAD_STATUS_REG have always had the same meaning since SNB. So treating them as something special for HSW doesn't make sense to me. Also the bits *seem* to work exactly the same way on IVB, HSW GT2 and HSW GT3. At least intel_reg_read gives the identical results on all platforms with and without forcewake. Also the HSW PM guide rev 0.99 (ww05 2013) doesn't say anything about those bits. It just says to poll for bits [2:0]. As does the more recent BDW PM guide. So just drop the HSW special case and treat all platforms the same way. Signed-off-by:

When reading out a DDI config that uses a PLL that is not part of the shared_dpll scheme (DPLL0), it's totally normal to end up in the default: case of that switch. Signed-off-by:

On chv the pipe-a power well is the new disp2d well, and it kills pretty much everything in the display block. So we need to do the the same dance that vlv does wrt. display irqs and hpd when the power well goes up or down. Signed-off-by:

Write and reads following the block changed use engine specific use counters and unless that is matched here force wake use counting goes bad. Same force wake is attempted to be taken twice which leads to at least time outs. NOTE: Depending on feedback from hardware designers it may not be necessary to grab force wakes on Gen9 here. But for Gen8 it is needed due to a race between RC6 and ELSP writes. v2: Added blitter force wake engine and made more future proof. Added commit note.

Ville found out that the DATA1 register exists since SNB with some scarce apparitions in the specs throughout the times. In his own words: Also according to Bspec the mailbox data1 register already existed since snb. The hsw cdclk change sequence also mentions that it should be set to 0, but eg. the bdw IPS sequence doesn't mention it. I guess in theory some pcode command might cause it to be clobbered, so I'm thinking we should just explicitly set it to 0 for all platforms in the pcode read/write functions Reviewed-by:

On skylake, DPLL 1, 2 and 3 can be used for DP and HDMI. The shared dpll framework allows us to share those DPLLs among DDIs when possible. The most tricky part is to provide a DPLL state that can be easily compared. DPLL_CRTL1 is shared by all the DPLLs, 6 bits each. The per-dpll crtl1 field of the hw state is then normalized to be the same value if 2 DPLLs do indeed have identical values for those 6 bits. v2: Port the code to the shared DPLL infrastructure (Damien) v3: Rebase on top of Ander's clock computation staging work for atomic (Damien) Reviewed-by: Paulo Zanoni <paulo.r.zanoni@intel.com> (v2) Signed-off-by: Satheeshakrishna M <satheeshakrishna.m@intel.com> (v1) Signed-off-by:
