Hi all,
So this is a little patch series that started very innocently as a small cleanup
in prep for some of the bigger features and then got out of hand. It now
implements runtime pm support for DPMS on everything that supports it.
Still rather lightly tested because of too many distractions this week.
After this series all the hw enabling is _only_ done in the ->enable hooks.
Encoder ->mode_set callbacks are completely gone and the crtc mode_set hooks
only do some pll state computations. This is a nice prep for atomic modesets too
since now all remaining code in the crtc mode_set callbacks must be moved out
into the preparatory compute_config stage. Unfortunately the code is tricky and
also depends upon the entire hw/sw state in tricky ways.
Anyway the entire pile nicely splits into sub-series, see below for in-line
comments.
Feedback and also testing from untime pm experts highly welcome. Presuming no
fundamental issues I'll sign up people for in-depth reviews soonish.
Cheers, Daniel

drm/i915: Make ->update_primary_plane infallible
drm/i915: More cargo-culted locking for intel_update_fbc
drm/i915: Sprinkle intel_edp_psr_update over crtc_enable/disable
drm/i915: Inline set_base into crtc_mode_set
drm/i915: Move fb pinning into __intel_set_mode
Some shuffling to get the primary->fb handling out of crtc mode_set callbacks
drm/i915: Shovel hw setup code out of i9xx_crtc_mode_set
drm/i915: Move lowfreq_avail around a bit in ilk/hsw_crtc_mode_set
drm/i915: Shovel hw setup code out of ilk_crtc_mode_set

drm/i915: Extract i9xx_set_pll_dividers
drm/i915: Extract vlv_prepare_pll
gmch pll moved out of crtc mode_set callbacks into ->enable hooks
drm/i915: Only update shared dpll state when needed
drm/i915: Extract intel_prepare_shared_dpll
drm/i915: s/ironlake_/intel_ for the enable_share_dpll function
Prep polish on the existing shared_dpll code
drm/i915: Check hw state in assert_can_disable_lcpll
drm/i915: Remove spll_refcount for hsw
drm/i915: Clean up WRPLL/SPLL #defines
drm/i915: Make intel_wait_for_pipe_off static
drm/i915: Disable pipe before ports on ilk
drm/i915: Pass port explicitly to intel_ddi_get_hw_state
drm/i915: Unexport intel_ddi_connector_get_hw_state
drm/i915: Move hsw_fdi_link_train into intel_crt.c
drm/i915: Move pch fifo underrun report enabling to hsw_crt_pre_enable
drm/i915: Move the SPLL enabling into hsw_crt_pre_enable
drm/i915: Move lpt_pch_enable int hsw_crt_enable
drm/i915: Move the pch fifo underrun handling into hsw_crt_disable
drm/i915: Move lpt_disable_pch_transcoder into the hsw crt encoder
drm/i915: Move pch fifo underrun report re-enabling into
hsw_crt_post_disable
drm/i915: Move the hsw fdi disabling into hsw_crt_post_disable
drm/i915: Move SPLL disabling into hsw_crt_post_disable
Create a new hsw-specific crt encoder which subsumes the entire fdi/pch handling
on haswell. This has the nice upshot to make SPLL logically a port-private clock
and so removes it from further considerations.
drm/i915: Add a debugfs file for the shared dpll state
drm/i915: Move ddi_pll_sel into the pipe config
drm/i915: State readout and cross-checking for ddi_pll_sel
drm/i915: Precompute static ddi_pll_sel values in encoders
drm/i915: Basic shared dpll support for WRPLLs
drm/i915: Document that the pll->mode_set hook is optional
drm/i915: State readout support for WRPLLs
drm/i915: ->disable hook for WRPLLs
drm/i915: ->enable hook for WRPLLs
drm/i915: Switch to common shared dpll framework for WRPLLs
drm/i915: Only touch WRPLL hw state in enable/disable hooks
Convert wrpll handling to the common shared_dpll framework. We need this since
runtime pm for dpms requires us to separately track pll refernces from crtcs and
active usage by crtcs
drm/i915: runtime PM support for DPMS
The final piece.
