      IXP42x HSS support for setting internal clock rate · 5dbc4650
      Krzysztof Halasa authored
      HSS usually uses external clocks, so it's not a big deal. Internal clock
      is used for direct DTE-DTE connections and when the DCE doesn't provide
      it's own clock.
      
      This also depends on the oscillator frequency. Intel seems to have
      calculated the clock register settings for 33.33 MHz (66.66 MHz timer
      base). Their settings seem quite suboptimal both in terms of average
      frequency (60 ppm is unacceptable for G.703 applications, their primary
      intended usage(?)) and jitter.
      
      Many (most?) platforms use a 33.333 MHz oscillator, a 10 ppm difference
      from Intel's base.
      
      Instead of creating static tables, I've created a procedure to program
      the HSS clock register. The register consists of 3 parts (A, B, C).
      The average frequency (= bit rate) is:
      66.66x MHz / (A  + (B + 1) / (C + 1))
      The procedure aims at the closest average frequency, possibly at the
      cost of increased jitter. Nobody would be able to directly drive an
      unbufferred transmitter with a HSS anyway, and the frequency error is
      what it really counts.
      
      I've verified the above with an oscilloscope on IXP425. It seems IXP46x
      and possibly IXP43x use a bit different clock generation algorithm - it
      looks like the avg frequency is:
      (on IXP465) 66.66x MHz / (A  + B / (C + 1)).
      Also they use much greater precomputed A and B - on IXP425 it would
      simply result in more jitter, but I don't know how does it work on
      IXP46x (perhaps 3 least significant bits aren't used?).
      
      Anyway it looks that they were aiming for exactly +60 ppm or -60 ppm,
      while <1 ppm is typically possible (with a synchronized clock, of
      course).
      
      The attached patch makes it possible to set almost any bit rate
      (my IXP425 533 MHz quits at > 22 Mb/s if a single port is used, and the
      minimum is ca. 65 Kb/s).
      
      This is independent of MVIP (multi-E1/T1 on one HSS) mode.

      WAN: remove deprecated PCI_DEVICE_ID from PCI200SYN driver. · 32e6a0c8
      Krzysztof Halasa authored
      PCI200SYN has its own PCI subsystem device ID for 3+ years, now it's
      time to remove the generic PLX905[02] ID from the driver. Anyone with
      old EEPROM data will have to run the upgrade.
      
      Having the generic PLX905[02] (PCI-local bus bridge) ID is harmful
      as the driver tries to handle other devices based on these bridges.
