[Intel-gfx] [PATCH] drm/i915: Don't preserve dpll_hw_state for slave crtc in Bigjoiner

[Intel-gfx] [PATCH] drm/i915: Don't preserve dpll_hw_state for slave crtc in Bigjoiner

[Stanislav Lisovskiy]

If we are using Bigjoiner dpll_hw_state is supposed to be exactly
same as for master crtc, so no need to save it's state for slave crtc.

I don't think that would help, here this is mostly a cosmetic fix
to remove dmesg warn caused by slave crtc sw/hw state mismatch, because
we don't calculate pll state for slave crtc in Bigjoiner, but still try
to verify it against the values in the correspodent hw.

I think that's one part of what's going in the bug, but I guess just for
a different phy.

Yeah, and the master has recalculated this already. I guess this
used to make some sense in the times when we did the dpll
calculations much later.

So probably deserves a

Seems like we should also remove it from the
intel_crtc_prepare_cleared_state() but that one clearly needs
much more thought due to the port_dpll[] stuff...
