Apparently the last reader of i915->active_pipes was removed with commit ef79d62b ("drm/i915: Encapsulate dbuf state handling harder"), and now it's only ever written to. Remove it completely.

The memory latency values returned by pcode on DG2 are in units of "2 usec" rather than 1 usec on all other platforms. I.e., we need to double the value returned by pcode to obtain the true latency value. The bspec wording here was a bit ambiguous as to whether it wanted us to multiply or divide the pcode value by two, but we confirmed offline with the hardware team that we need to double the value the pcode gives us; this change is intended to support a larger range of potential latency values.

On g4x and pch the DPLL has two P1 dividers (for refresh rate switching). Program the FPx1 P1 divider consistently to the reduced clock P1 divider if available, otherwise just program it to the same value as the FPx0 P1 divider. Signed-off-by:

The current gen2 DPLL readout code: * assumes i845/i865 have LVDS which is not true * assumes only pipe B can drive LVDS (true, but makes the code appear a bit magical) * hard to parse in general Clean it up by checking for i85x (the only gen2 platform with LVDS) and reusing intel_lvds_port_enabled().

When we enable the DPLL for the PPS kick, let's tell the DPLL code we're dealing with an eDP output. This shouldn't really matter, but it's more consistent with the way the DPLL is configured when we're actually enabling the eDP port for real. Signed-off-by:

The MST code uses actual link rates in the limits struct, while the DP code in general uses indexes to the ->common_rates[] array. Fix the confusion by using actual link rate values everywhere. This is a better abstraction than some obscure index. Rename the struct members while at it to ensure all the places are covered. Reviewed-by:
