[Intel-gfx] [PATCH 5/9] drm/i915: pnv dpll doesn't use m1!

[Daniel Vetter]

So don't try to store it in the DPLL_FP register.

Otherwise it looks like the limits for pineview are correct: It has
it's own clock computation code, which doesn't use an offset for n
divisors, and the register value based m limits look sane enough.

v2: Rebase on top of the pineview clock refactor and fixup up the
commit message: It's m1 pnv doens't care about, not m2!
