The commit 40893fd(net: switch to use skb_probe_transport_header())
involes a new error accidently. When NET_SKBUFF_DATA_USES_OFFSE is
not enabled, below compile error happens:
CC net/packet/af_packet.o
net/packet/af_packet.c: In function ‘packet_sendmsg_spkt’:
net/packet/af_packet.c:1516:2: error: implicit declaration of function ‘skb_probe_transport_header’ [-Werror=implicit-function-declaration]
cc1: some warnings being treated as errors
make[2]: *** [net/packet/af_packet.o] Error 1
make[1]: *** [net/packet] Error 2
make: *** [net] Error 2
As it seems skb_probe_transport_header() is not related to
NET_SKBUFF_DATA_USES_OFFSE, we should move the definition of
skb_probe_transport_header() out of scope of
NET_SKBUFF_DATA_USES_OFFSE macro.

- gen4 and earlier (save for g4x) only really have a 8bpc pipe, with
the possibility to dither to 6bpc using the panel fitter
- g4x has hdmi, but no 12 bpc pipe ... !? Clamp hdmi accordingly.
- TV/SDVO out are the only connectors available on platforms with
a pipe bpp != 8, add code to force the pipe to 8bpc unconditionally.
<rant>
The dither handling on gmch platforms is one giant disaster. I'm hoping
somewhat that vlv enabling will fix this up, but given that the 6bpc
handling for edp was simply added with another quick hack, I don't have
high hopes ...
</rant>
v2: Neither vlv nor g4x have 12bpc pipes. Still set pipe_bpp to 12*3,
but let the crtc code clamp things down to 10bpc on these platforms.
v3: Fix a bpc vs. bpp mixup in the gen4 and earlier pipe_bpp limiter
code.
v4: Drop the hunk in intel_hdmi.c about g4x/vlv 12bpc, it was wrong.

The old code only handled either 6bpc or 8bpc. Since it's easy to do,
reorganize the code to be a bit more generic so that it can also handle
10bpc and 12bpc. Note that we still start with 8bpc, so there's no
functional change.
Also, since we no don't need to compute the 6BPC flag in the mode_valid
callback, we can consolidate things a bit. That requires though that
the link bw computation is moved up in the compute_config callback.

The procedure has now 3 steps:
1. Compute the bpp that the plane will output, this is done in
pipe_config_set_bpp and stored into pipe_config->pipe_bpp. Also,
this function clamps the pipe_bpp to whatever limit the EDID of any
connected output specifies.
2. Adjust the pipe_bpp in the encoder and crtc functions, according to
whatever constraints there are.
3. Decide whether to use dither by comparing the stored plane bpp with
computed pipe_bpp.
There are a few slight functional changes in this patch:
- LVDS connector are now also going through the EDID clamping. But in
a 2nd change we now unconditionally force the lvds bpc value - this
shouldn't matter in reality when the panel setup is consistent, but
better safe than sorry.
- HDMI now forces the pipe_bpp to the selected value - I think that's
what we actually want, since otherwise at least the pixelclock
computations are wrong (I'm not sure whether the port would accept
e.g. 10 bpc when in 12bpc mode). Contrary to the old code, we pick
the next higher bpc value, since otherwise there's no way to make
use of the 12 bpc mode (since the next patch will remove the 12bpc
plane format, it doesn't exist).
Both of these changes are due to the removal of the
pipe_bpp = min(display_bpp, plane_bpp);
statement.
Another slight change is the reworking of the dp bpc code:
- For the mode_valid callback it's sufficient to only check whether
the mode would fit at the lowest bpc.
- The bandwidth computation code is a bit restructured: It now walks
all available bpp values in an outer loop and the codeblock that
computes derived values (once a good configuration is found) has been
moved out of the for loop maze. This is prep work to allow us to
successively fall back on bpc values, and also correctly support bpc
values != 8 or 6.
v2: Rebased on top of Paulo Zanoni's little refactoring to use more
drm dp helper functions.
v3: Rebased on top of Jani's eDP bpp fix and Ville's limited color
range work.
v4: Remove the INTEL_MODE_DP_FORCE_6BPC #define, no longer needed.
v5: Remove intel_crtc->bpp, too, and fix up the 12bpc check in the
hdmi code. Also fixup the bpp check in intel_dp.c, it'll get reworked
in a later patch though again.
v6: Fix spelling in a comment.
v7: Debug output improvements for the bpp computation.
v8: Fixup 6bpc lvds check - dual-link and 8bpc mode are different
things!
v9: Reinstate the fix to properly ignore the firmware edp bpp ... this
was lost in a rebase.
v10: Both g4x and vlv lack 12bpc pipes, so don't enforce that we have
that. Still unsure whether this is the way to go, but at least 6bpc
for a 8bpc hdmi output seems to work.
v11: And g4x/vlv also lack 12bpc hdmi support, so only support high
depth on DP. Adjust the code.
v12: Rebased.
v13: Split out the introduction of pipe_config->dither|pipe_bpp, as
requested from Jesse Barnes.
v14: Split out the special 6BPC handling for DP, as requested by Jesse

This is used way too often in the enable/disable paths. And will

Note that correct semantics of this change highly depend upon
correct updating of intel_crtc->config: Like with all other
modeset state, we need to call ->disable with the old config,
but ->mode_set and ->enable with the new config.
v2: Do not yet use the flag in the ->disable callbacks - atm we don't
yet have support for the information stored in the pipe_config in the

Only used by the lvds encoder. Note that we shouldn't do the same
simple conversion with the FORCE_6BPC flag, since that's much better
handled by moving all the pipe_bpc computation around.
This requires that we pass the pipe config around to encoders, so
that they can set special attributes and set constraints. To do so
introduce a new ->compute_config encoder callback, which is called in
stead of the drm crtc helper's ->mode_fixup.
To avoid massive churn all over the codebase we don't want to convert
all existing ->mode_fixup functions. Instead I've opted to convert
them on an as-needed basis (mostly to cut down on rebase conflicts and
to have more freedom to experiment around while developing the
patches).

During the introduction of the Allwinner SoC platforms, sunxi was
initially meant as a generic name for all the variants of the Allwinner
SoC.
It was ok at the time of the support of only the A10 and A13 that
look pretty much the same; but it's beginning to be troublesome with
the future addition of the Allwinner A31 (sun6i) that is quite
different, and would introduce some weird logic, where sunxi would
actually mean in some case sun4i and sun5i but without sun6i...
Moreover, it makes the compatible strings naming scheme not consistent
with other architectures, where usually for this kind of compability, we
just use the oldest SoC name that has this IP, so let's do just this.
