- there might be more TCONs that engines (mixers)

Handle both positive and negative dclk polarity,
according to bus_flags, taking care of this:
On A20 and similar SoCs, the only way to achieve Positive Edge
(Rising Edge), is setting dclk clock phase to 2/3(240°).
By default TCON works in Negative Edge(Falling Edge), this is why phase
is set to 0 in that case.
Unfortunately there's no way to logically invert dclk through IO_POL
register.
The only acceptable way to work, triple checked with scope,
is using clock phase set to 0° for Negative Edge and set to 240° for
Positive Edge.
On A33 and similar SoCs there would be a 90° phase option, but it divides
also dclk by 2.
This patch is a way to avoid quirks all around TCON and DOTCLOCK drivers
for using A33 90° phase divided by 2 and consequently increase code
complexity.
Check if panel is used. TCON can also handle VGA DAC, then panel could
be empty.

drm/sun4i: sun8i: Avoid clearing blending order at each atomic commit
Blending order is set based on the z position of each DRM plane. The
blending order register is currently cleared at each atomic DRM commit,
with the intent that each committed plane will set the appropriate
bits (based on its z-pos) when enabling the plane.
However, it sometimes happens that a particular plane is left unchanged
by an atomic commit and thus will not be configured again. In that
scenario, blending order is cleared and only the bits relevant for the
planes affected by the commit are set. This leaves the planes that did
not change without their blending order set in the register, leading
to that plane not being displayed.
Instead of clearing the blending order register at every atomic commit,
this change moves the register's initial clear at bind time and only
clears the bits for a specific plane when disabling it or changing its
zpos.
This way, planes that are left untouched by a DRM atomic commit are
no longer disabled.

drm/dp_helper: Add DP aux channel tracing
This is something we've needed for a very long time now, as it makes
debugging issues with faulty MST hubs along with debugging issues
regarding us interfacing with hubs correctly vastly easier to debug.
Currently this can actually be done if you trace the i2c devices for DP
using ftrace but that's significantly less useful for a couple of
reasons:
- Tracing the i2c devices through ftrace means all of the traces are
going to contain a lot of "garbage" output that we're sending over the
i2c line. Most of this garbage comes from retrying transactions, DRM's
helper library adding extra transactions to work around bad hubs, etc.
- Having a user set up ftrace so that they can provide debugging
information is a lot more difficult then being able to say "just boot
with drm.debug=0x100"
- We can potentially expand upon this tracing in the future to print
debugging information in regards to other DP transactions like MST
sideband transactions
This is inspired by a patch Rob Clark sent to do this a long time back.
Neither of us could find the patch however, so we both assumed it would
probably just be easier to rewrite it anyway.

drm/sun4i: Implement zpos for DE2
Initial implementation of DE2 planes only supported fixed zpos.
Expand implementation with configurable zpos property.
Implementation background:
Channel in DE2 driver represents one DRM plane, whereas pipe is just
mapped channel to known Z position. Pipe 0 will always be at the bottom,
pipe 1 just above pipe 0 and so on. If, for example, channel 1 is mapped
at pipe 0 and channel 0 at pipe 1, whatever is on channel 0 will appear
on top.
Before this commit, channel id was used for addressing channel related
registers (prefixed with SUN8I_MIXER_CHAN_UI_ or SUN8I_MIXER_CHAN_VI_)
and pipe registers (prefixed with SUN8I_MIXER_BLEND_). Additionally,
register SUN8I_MIXER_BLEND_ROUTE, which takes care for mapping channels
to pipes had fixed value. It mapped channel 0 to pipe 0, 1 to 1 and so
on. Consequence of all that was fixed Z order of planes.
With this commit, pipe registers are using zpos property as index and
channel related registers still use channel id as index. Pipe mapping
register is now set dynamically too and pipe enable register is rebuild
every time to make sure only active pipes are enabled.
Testing was done to confirm that there is no issues if bottom plane
contains pixels with alpha value < 0xff and if it doesn't whole screen.

drm/client: Fix: drm_client_new: Don't require DRM to be registered
Commit
894a677f4b3e ("drm/cma-helper: Use the generic fbdev emulation")
broke almost all drivers that use the CMA helper.
The reason is that drm_client_new() requires that the DRM device has
been registered, but the drivers register fbdev before registering DRM.
Remove the requirement that DRM should be registered when creating a
new client.

drm/panel: Make of_drm_find_panel() return an ERR_PTR() instead of NULL
Right now, the DRM panel logic returns NULL when a panel pointing to
the passed OF node is not present in the list of registered panels.
Most drivers interpret this NULL value as -EPROBE_DEFER, but we are
about to modify the semantic of of_drm_find_panel() and let the
framework return -ENODEV when the device node we're pointing to has
a status property that is not equal to "okay" or "ok".
Let's first patch the of_drm_find_panel() implementation to return
ERR_PTR(-EPROBE_DEFER) instead of NULL and patch all callers to replace
the '!panel' check by an 'IS_ERR(panel)' one.
