[PATCH v2 0/5] Do not re-read dpll registers

[PATCH v2 0/5] Do not re-read dpll registers

[Lucas De Marchi]

v2 of https://patchwork.freedesktop.org/series/58382/

Instead of re-reading the registers we just read on the hw state
readout, use the values saved on intel_shared_dpll. Besides not doing
the MMIO, this helps on sharing code since we don't have to
differentiate e.g. ICL and CNL because they have different registers for
the same thing.

Lucas De Marchi (5):
  drm/i915/skl: use previous pll hw readout
  drm/i915/bxt: make bxt_calc_pll_link() similar to skl
  drm/i915/cnl: use previous pll hw readout
  drm/i915/icl: use previous pll hw readout
  drm/i915/icl: reduce pll_id scope and use enum type

[PATCH v2 1/5] drm/i915/skl: use previous pll hw readout

[Lucas De Marchi]

By the time skl_ddi_clock_get() is called - and thus
skl_calc_wrpll_link() - we've just got the hw state from the pll
registers. We don't need to read them again: we can rather reuse what
was cached in the dpll_hw_state.

v2: rename state variable to pll_state, make argument const in
    skl_calc_wrpll_link() and remove not useful warning (from Ville)

This initialization seems a bit misplaced.

[PATCH v2 2/5] drm/i915/bxt: make bxt_calc_pll_link() similar to skl

[Lucas De Marchi]

Rename state to pll_state and use it as the argument to
bxt_calc_pll_link(), similar to how it's done in the skl variant.

The WARN_ON(!crtc_state->shared_dpll) is not very useful, so remove it
as well.

[PATCH v2 3/5] drm/i915/cnl: use previous pll hw readout

[Lucas De Marchi]

By the time cnl_ddi_clock_get() is called we've just got the hw state
from the pll registers. We don't need to read them again: we can rather
reuse what was cached in the dpll_hw_state.

This also affects the code for ICL since it partially reuses the CNL
code. However the more intricate part on ICL is left for another patch.

[PATCH v2 4/5] drm/i915/icl: use previous pll hw readout

[Lucas De Marchi]

By the time icl_ddi_clock_get() is called we've just got the hw state
from the pll registers. We don't need to read them again: we can rather
reuse what was cached in the dpll_hw_state.

While at it, s/refclk/ref_clock/ just to be consistent with the name
used in code nearby.
