When we pick a new power sequencer for the port but we're not doing a
full modeset, the power sequencer may have locked on to another port (or
no port). So kick it a bit to make sure it controls the port we want.
Again just like when we attempt to actually enable the DP port, we
must first write the port register with the approriate value except
the enable bit, and then we must enable the port to make the power
sequencer happy. In this case since we don't want the port actually
enabled we just toggle it on and immediately back off. Going forward
the power sequencer will keep working on that specific port until again
moved to another port.

When switching from one pipe to another, the power sequencer of the new
pipe seems to need a bit of kicking to lock into the port. Even the vdd
force bit doesn't work before the power sequencer has been sufficiently
kicked, so this must be done before any AUX transactions are attempted.
After extensive experimentation I've determined that it's sufficient
to first write the port register with the correct values except the
port must remain disabled, then we can do a second write to enable the
port, after which the power sequencer is operational and allows the port
to start up properly.
Contrary to my earlier theories we don't need to enable the port with
the idle pattern, so let's just use training pattern 1 as that's what
other platforms use here.

Since we read the current power seqeuncer delays from the registers
(as well as looking at the vbt and spec values) we may end up
corrupting delays we already initialized when we switch to another
pipe and the power seqeuncer there has different values currently
in the registers.
So make sure we only initialize the delays once even if
intel_dp_init_panel_power_sequencer() gets called multiple times.
There was some discussion in the review about when exactly we need to
unlock the pps. Quoting Bspec:
"If this bit is not a zero, it activates the register write protect
and writes to those registers will be ignored unless the write
protect key value is set in the panel sequencing control register."

The power seqeuncer delays are fixed for a given panel, so we can keep
them around once computed.
Not that on VLV/CHV we still re-compute them every time we initialize

want_panel_vdd is a bool so it can't cope with interleaving on/off calls
from multiple threads. If we want to make that possible we'd need to
convert want_panel_vdd into a proper ref count. But an easier fix is to
remove the high level vdd on/off calls from detect/hpd code paths and
just rely on the delayed vdd off to avoid needless vdd on<->off ping
pong.
After this change only the encoder enable/disable paths use the high
level functions, which is fine since both the on and off low level edp
vdd calls from intel_dp_aux_ch() happen without dropping pps_mutex in
between and so want_panel_vdd can't change in between.

Because I got annoyed that I had to document what values "int
ddi_personality" is supposed to hold.
A good side-effect of this change is that now the compilers can do
some additional checks on our code, which may prevent some bugs in the
future. A bad side-effect of this change is that now the compilers do
some additional checks on our code and complain when a switch
statement doesn't check for all possible values, so we need to add
"default" cases to all those switches. Hopefully, this may help
preventing confusions against DRM_MODE_CONNECTOR_* and
DRM_MODE_ENCODER_*.
I guess that just by looking at the patch, some people will think this
change is not worth its benefits. In this case, I don't really mind
dropping the patch.
Also, there's probably still a few more places where we can
s/int/enum intel_output_type/, but we can change that later, when we
spot the places.

libva uses chained batch buffers in a way that the command parser
can't generally handle. Fortunately, libva doesn't need to write
registers from batch buffers in the way that mesa does, so this
patch causes the driver to fall back to non-secure dispatch if
the parser detects a chained batch buffer.
Note: The 2nd hunk to munge the error code of the parser looks a bit
superflous. At least until we have the batch copy code ready and can
run the cmd parser in granting mode. But it isn't since we still need
to let existing libva buffers pass (though not with elevated privs
ofc!).

The string property read helpers will run off the end of the buffer if
it is handed a malformed string property. Rework the parsers to make
sure that doesn't happen. At the same time add new test cases to make
sure the functions behave themselves.
The original implementations of of_property_read_string_index() and
of_property_count_strings() both open-coded the same block of parsing
code, each with it's own subtly different bugs. The fix here merges
functions into a single helper and makes the original functions static
inline wrappers around the helper.
One non-bugfix aspect of this patch is the addition of a new wrapper,
of_property_read_string_array(). The new wrapper is needed by the
device_properties feature that Rafael is working on and planning to
merge for v3.19. The implementation is identical both with and without
the new static inline wrapper, so it just got left in to reduce the
churn on the header file.

So far, the required PLL's (PLL1/PLL2/PLL5) have been initialized
by boot loader and the kernel code defined fixed rates according
to those default configurations. Beginning with the USB PLL7 the
code started to initialize the PLL's itself (using imx_clk_pllv3).
However, since commit dc4805c2e78ba5a22ea1632f3e3e4ee601a1743b
(ARM: imx: remove ENABLE and BYPASS bits from clk-pllv3 driver)
imx_clk_pllv3 no longer takes care of the ENABLE and BYPASS bits,
hence the USB PLL were not configured correctly anymore.
This patch not only fixes those USB PLL's, but also makes use of
the imx_clk_pllv3 for all PLL's and alignes the code with the PLL
support of the i.MX6 series.

It is safe to call notify disconnect when the usb core
thinks the device is disconnected.
This commit also fixes one bug found at below situation:
we have not enabled usb wakeup, we do system suspend when
there is an usb device at the port, after suspend, we plug out
the usb device, then plug in device again. At that time,
the nofity disconnect was not called at current code, as
the controller doesn't know the usb device was disconnected
during the suspend, but USB core knows the port has changed
during that periods.
So to fix this problem, and let the usb core call notify disconnect.

which is known to work fine with other controllers causes the system to freeze
when connected over usb-3 with this controller, where as it works fine with
uas in usb-2 ports, indicating a problem with streams.
This is a bit bigger hammer then I would like to use for this, but for now it
will have to make do. I've ordered a pci-e usb controller card with an Asmedia
1042, once that arrives I'll try to get streams to work (with a quirk flag if
necessary) and then we can re-enable them. For now this at least makes uas
capable disk enclosures work again by forcing fallback to the usb-storage
driver.

We wanted to print the version as (major).(minor) but because the shift
operation is higher precedence than the mask then we print
(minor).(minor).
