The CMA helper is already using the drm_fb_helper_generic_probe part of
the generic fbdev emulation. This patch makes full use of the generic
fbdev emulation by using its drm_client callbacks. This means that
drm_mode_config_funcs->output_poll_changed and drm_driver->lastclose are
now handled by the emulation code. Additionally fbdev unregister happens
automatically on drm_dev_unregister().
The drm_fbdev_generic_setup() call is put after drm_dev_register() in the
driver. This is done to highlight the fact that fbdev emulation is an
internal client that makes use of the driver, it is not part of the
driver as such. If fbdev setup fails, an error is printed, but the driver
succeeds probing.
drm_fbdev_generic_setup() handles mode_config.num_connector being zero.
In that case it retries fbdev setup on the next .output_poll_changed.

Group start/stop is controlled by the DRES and DEN bits of DSYSR0 for
the first group and DSYSR2 for the second group. On most DU instances,
this maps to the first CRTC of the group. On M3-N, however, DU2 doesn't
exist, but DSYSR2 does. There is no CRTC object there that maps to the
correct DSYSR register.
Commit 9144adc5e5a9 ("drm: rcar-du: Cache DSYSR value to ensure known
initial value") switched group start/stop from using group read/write
access to DSYSR to a CRTC-based API to cache the DSYSR value. While
doing so, it introduced a regression on M3-N by accessing DSYSR3 instead
of DSYSR2 to start/stop the second group.
To fix this, access the DSYSR register directly through group read/write
if the SoC is missing the first DU channel of the group. Keep using the
rcar_du_crtc_dsysr_clr_set() function otherwise, to retain the DSYSR
caching feature.

The official way to stop the display is to clear the display enable
(DEN) bit in the DSYSR register, but that operates at a group level and
affects the two channels in the group. To disable channels selectively,
the driver uses TV sync mode that stops display operation on the channel
and turns output signals into inputs.
While TV sync mode is available in all DU models currently supported,
the D3 and E3 DUs don't support it. We will thus need to find an
alternative way to turn channels off.
In the meantime, condition the switch to TV sync mode to the
availability of the feature, to avoid writing an invalid value to the
DSYSR register. When the feature is unavailable the display output will
turn blank as all planes are disabled when stopping the CRTC.

DSYSR is a DU channel register that also contains group fields. It is
thus written to by both the group and CRTC code, using read-update-write
sequences. As the register isn't initialized explicitly at startup time,
this can lead to invalid or otherwise unexpected values being written to
some of the fields if they have been modified by the firmware or just
not reset properly.
To fix this we can write a fully known value to the DSYSR register when
turning a channel's functional clock on. However, the mix of group and
channel fields complicate this. A simpler solution is to cache the
register and initialize the cached value to the desired hardware
defaults.

All Gen3 SoCs supported so far have a fixed association between DPAD0
and DU channels, which led to hardcoding that association when writing
the corresponding hardware register. The D3 and E3 will break that
mechanism as DPAD0 can be dynamically connected to either DU0 or DU1.
Make DPAD0 routing dynamic on Gen3. To ensure a valid hardware
configuration when the DU starts without the RGB output enabled, DPAD0
is associated at initialization time to the first DU channel that it can
be connected to. This makes no change on Gen2 as all Gen2 SoCs can
connected DPAD0 to DU0, which is the current implicit default value.
As the DPAD0 source is always 0 when a single source is possible on
Gen2, we can also simplify the Gen2 code in the same function to remove
a conditional check.

On selected SoCs, the DU can use the clock output by the LVDS encoder
PLL as its input dot clock. This feature is optional, but on the D3 and
E3 SoC it is often the only way to obtain a precise dot clock frequency,
as the other available clocks (CPG-generated clock and external clock)
usually have fixed rates.
Add a DU model information field to describe which DU channels can use
the LVDS PLL output clock as their input clock, and configure clock
routing accordingly.
This feature is available on H2, M2-W, M2-N, D3 and E3 SoCs, with D3 and
E3 being the primary targets. It is left disabled in this commit, and
will be enabled per-SoC after careful testing.
At the hardware level, clock routing is configured at runtime in two
steps, first selecting an internal dot clock between the LVDS PLL clock
and the external DOTCLKIN clock, and then selecting between the internal
dot clock and the CPG-generated clock. The first part requires stopping
the whole DU group in order for the change to take effect, thus causing
flickering on the screen. For this reason we currently hardcode the
clock source to the LVDS PLL clock if available, and allow flicker-free
selection of the external DOTCLKIN clock or CPG-generated clock
otherwise. A more dynamic clock selection process can be implemented
later if the need arises.

The LVDS encoders in the D3 and E3 SoCs differ significantly from those
in the other R-Car Gen3 family members:
- The LVDS PLL architecture is more complex and requires computing PLL
parameters manually.
- The PLL uses external clocks as inputs, which need to be retrieved
from DT.
- In addition to the different PLL setup, the startup sequence has
changed *again* (seems someone had trouble making his/her mind).
Supporting all this requires DT bindings extensions for external clocks,
brand new PLL setup code, and a few quirks to handle the differences in
the startup sequence.
The implementation doesn't support all hardware features yet, namely
- Using the LV[01] clocks generated by the CPG as PLL input.
- Providing the LVDS PLL clock to the DU for use with the RGB output.
Those features can be added later when the need will arise.

The ESCR and OTAR registers exist in each DU channel, but at different
offsets for odd and even channels. This led to usage of the group
register access API to write them, with offsets macros named ESCR/OTAR
and ESCR2/OTAR2 for the first and second ESCR/OTAR register in the group
respectively.
The names are confusing as it suggests that the ESCR/OTAR registers for
DU0 and DU2 are taken into account, especially with writes performed to
the group register access API.
Rename the offsets to ESCR/OTAR02 and ESCR/OTAR13, and use the CRTC
register access API to clarify the code. The offsets values are updated
accordingly.

DU channels not equipped with a DPLL use an SoC internal (provided by
the CPG) or external clock source combined with a DU internal divider to
generate the desired output dot clock frequency.
The current clock selection procedure does not fully exploit the ability
of external clock sources to generate the exact dot clock frequency by
themselves, but relies instead on tuning the internal DU clock divider
only, resulting in a less precise clock generation process.
When possible, and desirable, ask the external clock source for the
exact output dot clock frequency, and select the clock source that
produces the frequency closest to the desired output dot clock.
This patch specifically targets platforms (like Salvator-X[S] and ULCBs)
where the DU's input dotclock.in is generated by the versaclock VC5
clock source, which is capable of generating the exact rate the DU needs
as pixel clock output.
This patch fixes higher resolution modes which requires an high pixel
clock output currently not working on non-HDMI DU channel (such as
1920x1080@60Hz on the VGA output).

A new helper function(__drm_atomic_helper_plane_reset) has been added
for linking a plane with its state and resetting the core
properties(alpha, rotation, etc.) to their default values.
Use that instead of duplicating the logic.
__drm_atomic_helper_plane_reset initializes the alpha property to its
max value, which is defined by the drm core as DRM_BLEND_ALPHA_OPAQUE,
so nothing changes regarding the alpha value.

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.

The connector .atomic_check() handler can be called with a NULL crtc
pointer in the connector state when the connector gets disabled
explicitly (through performing a legacy mode set or setting the
connector's CRTC_ID property to 0). This causes a crash as the crtc
pointer is dereferenced without any check.
Fix it by returning from the .atomic_check() handler when then crtc
pointer is NULL, as there is no check to be performed when the connector
gets disabled.

Commit 75a07f399cd4 ("drm: rcar-du: Zero-out sg_tables when duplicating
plane state") introduced a reference to the alpha field of struct
rcar_du_vsp_plane_state that got removed in commit 301a9b8d5456
("drm/rcar-du: Convert to the new generic alpha property"). The issue
stems from the merge of the two commits through separate branches and
breaks compilation of the driver. Fix it.

The rcar_du_of_init() function is supposed to be defined as a stub when
CONFIG_DRM_RCAR_LVDS is disabled as the rcar_du_of.c file isn't compiled
in that case. However, a bug in the configuration option check makes it
a stub when CONFIG_DRM_RCAR_LVDS=m as well, which prevents legacy DTs
from being fixed at boot time. Fix the configuration option check by
using IS_ENABLED.

The rcar DT overlays are missing symetrical remote-endpoint properties
in their graph nodes because the remote-endpoint is fixed up at
run-time. Disable the dtc 'graph-endpoint' warnings when compiling these
overlays. If this becomes a common problem for overlays, then perhaps
this check needs to be disabled for all overlays.
