[Intel-gfx] [PATCH 00/13] Shared pll improvements

[Ander Conselvan de Oliveira]

Hi,

This patch series attempts to improve the shared pll interfaces. The
idea is to hide the details of which PLL to use behind the call to
intel_get_shared_dpll(), instead of having the weird mix currently
used with DDI platforms. I plan to keep working on the interfaces to
make it usuable by other platforms too, but that will come in a later
series.

With these patches, all DPLLS used with DDI are managed, including
LCPLL in HSW/BDW and DPLL0 in SKL/KBL (although I wasn't able to test
the latter).

The avid reviewer might notice that this series leaves all the
*_ddi_pll_select() function looking pretty much the same. I have
a clean up lined up for that, but it involves removing the
haswell_crtc_compute_clock() function and I haven't yet figured out
how/where to release the used dplls.

So this is still work in progress, but it is probably better to get
feedback now before there are even more patches.

Thanks,
Ander
