This reverts commit 03752f5b7b.
This revert requires a bit of explanation on how I understand things
work. Internally the architects/designers decide how the stolen encoding
works. We put it in a doc. BIOS writers take these docs and implement
it. Driver writers read the doc too, and read the value left by the BIOS
writers, and then we make magic.
The failing here is that in the docs we had[1] contained two different
definitions for this register for Gen7. (We have both a PCI register,
and an MMIO, and each of these were different). At the time [2] of
03752f5, we asked the architects what the correct value should be; but
that doesn't match the reality (BIOS) unfortunately.
So on all machines I can get my hands on, this revert is the right thing
to do. I've also worked with the product group to confirm that they
agree this revert is what we should do. People using HW made my "people"
who both write their own BIOS, and have access to our docs (Apple?).
Investigations are still ongoing about whether we need to add a list
of machines needing special handling, but this patch should be the
right thing for pretty much everyone.
[1] The docs are still wrong on this one. Now instead of two registers with
two definitions, we have one register with BOTH definitions, progress?
[2] The open source PRMs have the "wrong" definitions in chapter Volume
1 part6, section 1.1.12.
This digging was inspired by Paulo.

According to BSpec the link training sequence for eDP on HSW port-A
should be as follows:
1. link training: clock recovery
2. link training: equalization
3. link training: set idle transmission mode
4. display pipe enable
5. link training: disable (set normal mode)
Contrary to this at the moment we don't do step 3. and we do step 5.
before step 4. Fix this by setting idle transmission mode for eDP at
the end of intel_dp_complete_link_train and adding a new
intel_dp_stop_link_training function to disable link training. With
these changes we'll end up with the following functions corresponding
to the above steps:
intel_dp_start_link_train -> step 1.
intel_dp_complete_link_train -> step 2., step 3.
intel_dp_stop_link_train -> step 5.
For port-A we'll call intel_dp_stop_link_train only after enabling the
pipe, for everything else we'll call it right after
intel_dp_complete_link_train to preserve the current behavior.
Tested on HSW/HSW-ULT.
In v2:
- Due to a HW issue we must set idle transmission mode for port-A too
before enabling the pipe. Thanks for Arthur Runyan for explaining
this.
- Update the patch subject to make it clear that it's an eDP fix, DP is
not affected.
v3:
- rename intel_dp_link_train() to intel_dp_set_link_train(), use 'val'
instead 'l' as var name. (Paulo)

Pull i2c changes from Wolfram Sang:
- an arbitration driver. While the driver is quite simple, it caused
discussion if we need additional arbitration on top of the one
specified in the I2C standard. Conclusion is that I accept a few
generic mechanisms, but not very specific ones.
- the core lost the detach_adapter() call. It has no users anymore and
was in the way for other cleanups. attach_adapter() is sadly still
there since there are users waiting to be converted.
- the core gained a bus recovery infrastructure. I2C defines a way to
recover if the data line is stalled. This mechanism is now in the
core and drivers can now pass some data to make use of it.
- bigger driver cleanups for designware, s3c2410
- removing superfluous refcounting from drivers
- removing Ben Dooks as second maintainer due to inactivity. Thanks
