Two patches from the R40 display pipeline support series weren't applied
with the rest of the series. When they did get applied, the -rc6
deadline for drm-misc-next had past, so they didn't get into 4.19-rc1
with the rest of the series. However, the two patches are crucial in
the parsing of the R40's display pipeline graph in the device tree.
Without them, the driver crashes because it can't follow the odd graph
structure.
This patch removes the R40 compatibles from the sun4i-drm driver,
effectively disabling DRM support for the R40 for one release cycle.
This will prevent the driver from crashing upon probing.
The compatibles should be reinstated for the next release.

This patch unifies the naming of DRM functions for reference counting

Having DRM_SUN4I built-in but DRM_SUN8I_MIXER as a loadable module results in
a link error, as we try to access a symbol from the sun8i_tcon_top.ko module:
ERROR: "sun8i_tcon_top_of_table" [drivers/gpu/drm/sun4i/sun8i-drm-hdmi.ko] undefined!
ERROR: "sun8i_tcon_top_of_table" [drivers/gpu/drm/sun4i/sun4i-drm.ko] undefined!
This solves the problem by adding a silent symbol for the tcon_top module,
building it as a separate module in exactly the cases that we need it,
but in a way that it is reachable by the other modules.

TV TCONs (channel 1 only) are always connected to TV or HDMI encoder.
Because of that, all output endpoints on such TCON node will point to a
encoder which is part of component framework.

Until now, each node has one input port and one output port. However,
with TCON TOP this is no longer true. It has 3 input and 3 output ports.
In order to prepare to this situation, split out the code which checks
all endpoints in input port and adds available components to fifo.
This patch doesn't do any functional change.

The display frontend is an hardware block that can be used to implement
some more advanced features like hardware scaling or colorspace
conversions. It can also be used to implement the output format of the VPU.
Let's create a minimal driver for it that will only enable the hardware
scaling features.

Use drm_fb_cma_fbdev_init() and drm_fb_cma_fbdev_fini() which relies on
the fact that drm_device holds a pointer to the drm_fb_helper structure.
This means that the driver doesn't have to keep track of that.
Also use the drm_fb_helper functions directly.

The sun4i DRM driver maintains a list of compatible strings it uses to
check if a device node within the display component graph is a TCON.
The TCON driver also has this list, used to bind the TCON driver to
the device. These two lists are identical.
Instead of maintaining two identical lists, export the list from the
TCON driver for the DRM driver to use.

The commit da82b8785eeb ("drm/sun4i: add components in breadth first
traversal order") implemented a breadth first traversal of our device tree
nodes graph. However, it was relying on the kernel linked lists, and those
are not really safe for addition.
Indeed, in a single pipeline stage, your first stage (ie, the mixer or
fronted) will be queued, and it will be the final iteration of that list as
far as list_for_each_entry_safe is concerned. Then, during that final
iteration, we'll queue another element (the TCON or the backend) that
list_for_each_entry_safe will not account for, and we will leave the loop
without having iterated over all the elements. And since we won't have
built our components list properly, the DRM driver will be left
non-functional.
We can instead use a kfifo to queue and enqueue components in-order, as was
the original intention. This also has the benefit of removing any dynamic
allocation, making the error handling path simpler too. The only thing
we're losing is the ability to tell whether an element has already been
queued, but that was only needed to remove spurious logs, and therefore
purely cosmetic.
This means that this commit effectively reverses e8afb7b67fba ("drm/sun4i:
don't add components that are already in the queue").

Even though the components framework can handle duplicate entries,
the extra entries cause a lot more debug messages to be generated,
which would be confusing to developers not familiar with our driver
and the framework in general.
Instead, we can scan the relatively small queue and check if the
component to be added is already queued up. Since the display
pipelines are symmetrical (not considering the third display
pipeline on the A80), and we add components level by level, when
we get to the second instance at the same level, any shared downstream
components would already be in the queue.

If we want to have vblank on both pipelines at the same time, we need
to call drm_vblank_init with num_crtcs = 2.
Instead, since the crtc init calls correctly set mode_config.num_crtc,
we can move the drm_vblank_init call to after the crtc init code is
called, which is the component bind part. Then we can just pass
mode_config.num_crtc in.

The encoder drivers use drm_of_find_possible_crtcs to get upstream
crtcs from the device tree using of_graph. For the results to be
correct, encoders must be probed/bound after _all_ crtcs have been
created. The existing code uses a depth first recursive traversal
of the of_graph, which means the encoders downstream of the TCON
get add right after the first TCON. The second TCON or CRTC will
never be properly associated with encoders connected to it.
Other platforms, such as Rockchip, deal with this by probing all
CRTCs first, then all subsequent components. This is easy to do
since the CRTCs correspond to just one device node, and are the
first nodes in the pipeline.
However with Allwinner SoCs, the function of the CRTC is split
between the display backend (DE 1.0) or mixer (DE 2.0), which does
scan-out and compositing, and the TCON, which generates the display
timing signals. Further complicating the process, there may be a
Dynamic Range Controller between the backend and the TCON. Also, the
backend is preceded by the frontend, with a Display Enhancement Unit
possibly in between.
In a dual display pipeline setup, both frontends can feed either
backend, and both backends can feed either TCON. We want all
components of the same type to be added before the next type in the
pipeline. Fortunately, the pipelines are perfectly symmetric, i.e.
components of the same type are at the same depth when counted from
the frontend. The only exception is the third pipeline in the A80
SoC, which we do not support anyway.
Hence we can use a breadth first search traversal order to add
components. We do not need to check for duplicates. The component
matching system handles this for us.

sun4i-drm changes for 4.13
An unusually big pull request for this merge window, with three notable
features:
- V3s display engine support. This is especially notable because it uses
a different display engine used on the newer Allwinner SoCs (H3, A64
and the likes) that will be quite easily supported now.
- HDMI support for the old Allwinner SoCs. This is enabled only on the
A10s for now, but should be really easy to extend to deal with A10, A20
and A31
- Preliminary work to deal with dual-pipeline SoCs (A10, A20, A31, H3,
etc.). It currently ignores the second pipeline, but we can use the
dual-pipelines bindings. This will be useful to enable the display
pipeline while we work on the dual-pipeline.

As we are going to add support for the Allwinner DE2 engine in sun4i-drm
driver, we will finally have two types of display engines -- the DE1
backend and the DE2 mixer. They both do some display blending and feed
graphics data to TCON, and is part of the "Display Engine" called by
Allwinner, so I choose to call them both "engine" here.
Abstract the engine type to a new struct with an ops struct, which contains
functions that should be called outside the engine-specified code (in
TCON, CRTC or TV Encoder code).
In order to preserve bisectability, we also switch the backend and layer
code in its own module.

Allow to provide an optional memory region to allocate from for our DRM

The tcon provides part of the functionality of the crtc, and also
provides the device node for the output port of the crtc. To be able
to use drm_of_find_possible_crtcs(), all crtc must be initialized before
any downstream encoders. The other part of the crtc is the display
backend.
The Rockchip DRM driver does this by first binding all vops, which is
their crtc, and this step also creates the crtc objects. Then all
remaining hardware components are bound. With the Allwinner display
pipeline, we have multiple components comprising the crtc, and varying
depths of the display pipeline. Since components are added with a depth
first search of the of_graph, we can initialize the crtc object within
the tcon bind function. Since the backend precedes the tcon, and the
backends cannot be muxed or switched around, we can be sure that the
associated backend is already initialized.
This patch also moves the crtc pointer from the main drm_device data to
the tcon device data. Besides the crtc callbacks, the crtc structure is
only used within the tcon driver to signal vblank events from its
interrupt handler.
As the crtc and layer bits are now called from the tcon bits, we must
move them from the sun4i-drm module to the sun4i-tcon module to avoid
circular dependencies between the two modules. This is because sun4i-drm
also calls into sun4i-tcon.

This patch moves the sun4i_layers_init call from sun4i_drv_bind to
sun4i_crtc_init, and the layers pointer from struct sun4i_drv to
struct sun4i_crtc.
The layers are bound to a specific crtc, and they are not directly
used once initiated. They are used through their included drm_plane
structures.
Moving the layers into the crtc facilitates binding them to the crtc
explicitly, by setting the corresponding bit in their .possible_crtcs
fields right after the crtc is initialized. This is done in a later
patch.

The master bind function calls numerous drm functions which initialize
underlying structures. It also tries to bind the various components
of the display pipeline, some of which may add additional drm objects.
This patch adds proper cleanup functions in the error path of the
master bind function.
This requires the patch "drm/sun4i: Move drm_mode_config_cleanup call
to main driver", which splits out drm_mode_config_cleanup from
sun4i_framebuffer_free so we can call it separately.

Less code ftw.
This converts all drivers except the tinydrm helper module. That one
needs more work, since it gets the THIS_MODULE reference from
tinydrm.ko instead of the actual driver module like it should.
Probably needs a similar trick like I used here with generating the
entire struct with a macro.

Core code already makes drm_driver.get_vblank_counter hook optional by
letting drm_vblank_no_hw_counter be the default implementation for the
