      phy: rockchip-typec: Don't set the aux voltage swing to 400 mV · 26e03d80
      Douglas Anderson authored
      On rk3399-gru-kevin there are some cases where we're seeing AUX CH
      failures when trying to do DisplayPort over type C.  Problems are
      intermittent and don't reproduce all the time.  Problems are often
      bursty and failures persist for several seconds before going away.
      The failure case I focused on is:
      * A particular type C to HDMI adapter.
      * One orientation (flip mode) of that adapter.
      * Easier to see failures when something is plugged into the _other
        type C port at the same time.
      * Problems reproduce on both type C ports (left and right side).
      
      Ironically problems also stop reproducing when I solder wires onto the
      AUX CH signals on a port (even if no scope is connected to the
      signals).  In this case, problems only stop reproducing on the port
      with the wires connected.
      
      From the above it appears that something about the signaling on the
      aux channel is marginal and any slight differences can bring us over
      the edge to failure.
      
      It turns out that we can fix our problems by just increasing the
      voltage swing of the AUX CH, giving us a bunch of extra margin.  In DP
      up to version 1.2 the voltage swing on the aux channel was specced as
      .29 V to 1.38 V.  In DP version 1.3 the aux channel voltage was
      tightened to be between .29 V and .40 V, but it clarifies that it
      really only needs the lower voltage when operating at the highest
      speed (HBR3 mode).  So right now we are trying to use a voltage that
      technically should be valid for all versions of the spec (including
      version 1.3 when transmitting at HBR3).  That would be great to do if
      it worked reliably.  ...but it doesn't seem to.
      
      It turns out that if you continue to read through the DP part of the
      rk3399 TRM and other parts of the type C PHY spec you'll find out that
      while the rk3399 does support DP 1.3, it doesn't support HBR3.  The
      docs specifically say "RBR, HBR and HBR2 data rates only".  Thus there
      is actually no requirement to support an AUX CH swing of .4 V.
      
      Even if there is no actual requirement to support the tighter voltage
      swing, one could possibly argue that we should support it anyway.  The
      DP spec clarifies that the lower voltage on the AUX CH will reduce
      cross talk in some cases and that seems like it could be beneficial
      even at the lower bit rates.  At the moment, though, we are seeing
      problems with the AUX CH and not on the other lines.  Also, checking
      another known working and similar laptop shows that the other laptop
      runs the AUX channel at a higher voltage.
      
      Other notes:
      * Looking at measurements done on the AUX CH we weren't actually
        compliant with the DP 1.3 spec anyway.  AUX CH peek-to-peek voltage
        was measured on rk3399-gru-kevin as .466 V which is > .4 V.
      * With this new patch the AUX channel isn't actually 1.0 V, but it has
        been confirmed that the signal is better and has more margin.  Eye
        diagram passes.
      * If someone were truly an expert in the Type C PHY and in DisplayPort
        signaling they might be able to make things work and keep the
        voltage at < .4 V.  The Type C PHY seems to have a plethora of
        tuning knobs that could almost certainly improve the signal
        integrity.  Some of these things (like enabling tx_fcm_full_margin)
        even seem to fix my problems.  However, lacking expertise I can't
        say whether this is a better or worse solution.  Tightening signals
        to give cleaner waveforms can often have adverse affects, like
        increasing EMI or adding noise to other signals.  I'd rather not
        tune things like this without a healthy application of expertise
        that I don't have.

      phy: rockchip-typec: Set the AUX channel flip state earlier · f98b7438
      Douglas Anderson authored
      On some DP monitors we found that setting the wrong flip state on the
      AUX channel could cause the monitor to stop asserting HotPlug Detect
      (HPD).  Setting the right flip state caused these monitors to start
      asserting HotPlug Detect again.
      
      Here's what we believe was happening:
      * We'd plug in the monitor and we'd see HPD assert
      * We'd quickly see HPD deassert
      * The kernel would try to init the type C PHY but would init it in USB
        mode (because there was a peripheral there but no HPD)
      * Because the kernel never set the flip mode properly we'd never see
        the HPD come back.
      
      With this change, we'll still see HPD disappear (we don't think
      there's anything we can do about that), but then it will come back.
      
      Overall we can say that it's sane to set the AUX channel flip state
      even when HPD is not asserted.
      
      NOTE: to make this change possible, I needed to do a bit of cleanup to
      the tcphy_dp_aux_calibration() function so that it doesn't ever
      clobber the FLIP state.  This made it very obvious that a line of code
      documented as "setting bit 12" also did a bunch of other magic,
      undocumented stuff.  For now I'll just break out the bits and add a
      comment that this is black magic and we'll try to document
      tcphy_dp_aux_calibration() better in a future CL.
      
      ALSO NOTE: the old function used to write a bunch of hardcoded
      values in _some_ cases instead of doing a read-modify-write.  One
      could possibly assert that these could have had (beneficial) side
      effects and thus with this new code (which always does
      read-modify-write) we could have a bug.  We shouldn't need to worry,
      though, since in the old code tcphy_dp_aux_calibration() was always
      called following the de-assertion of "reset" the the type C PHY.
      ...so the type C PHY was always in default state.  TX_ANA_CTRL_REG_1
      is documented to be 0x0 after reset.  This was also confirmed by
      printk.

      This restores the ability to build firmware directly into the kernel by
      pruning the original Makefile to the necessary minimum.  The default for
      EXTRA_FIRMWARE_DIR is now the standard directory /lib/firmware/.
