The cros_ec driver currently assumes that cros-ec-spi compatible device
nodes are a wakeup-source even though the wakeup-source property is not
defined.
Some Chromebooks use a separate wake pin, while others overload the
interrupt for wake and IO. With the current assumption, spurious wakes
can occur on systems that use a separate wake pin. It is planned to
update the driver to no longer assume that the EC interrupt pin should
be enabled for wake.
Add the wakeup-source property to all cros-ec-spi compatible device
nodes to signify to the driver that they should still be a valid wakeup
source.

Similar to sc7180 (see the patch ("arm64: dts: qcom: sc7180: Fix
trogdor qspi pin config")), we should adjust the qspi pin config for
sc7280.
I won't re-describe all the research/arguments in the sc7180 patch
here, but there are a few differences for sc7280 worth noting:
1. On herobrine the SPI flash (qspi) is wired up differently on the
board. Rather than Cr50 and the AP being wired directly together,
there's actually a mux that will _either_ connect the AP to the
flash or Cr50 to the flash. This means that the internal pulls on
Cr50 don't affect us and we should enable our own pulldowns.
2. On herobrine, EEs added an external pulldown on the MISO line. The
argument in the schematic said that we added it (but not one on
MOSI and CLK) because Cr50 already enabled pulldowns on MOSI and
CLK. ...though, as per #1, those Cr50 pulldowns would only affect
the line when the mux was swung to Cr50.
The ironic result of #1 and #2 is that the external pulldowns on
CLK/MISO/MOSI on herobrine are _exactly opposite_ of the ones on
trogdor.
3. While I still don't have the actual exact schematics for all
variants of IDP/CRD that were produced, I have some reference
schematics that give me a belief of how the qspi is hooked up
there. From this, I'm fairly certain that all of the older variants
of IDP/CRD either have a pulldown on the CLK/MOSI/MISO lines (maybe
through a direct connect to Cr50) or have no pull (in other words,
they don't have a pullup). I'll go ahead and enable internal
pulldowns on all the lines since that won't hurt to double-pull if
there's an external pulldown and it's nice to have a pulldown if
there's nothing external. Note that this only affects _older_
CRDs. Newer revs are considered "herobrine" (see the hoglin/zoglin
device trees).
4. I didn't find the same strange "auto-switch-to-keeper" at suspend
when probing on sc7280. Whatever pulls (or lack thereof) I left at
suspend time seemed to persist into suspend.

There are some interop issues seen across a few DP monitors with
HBR3 and herobrine boards where the DP display stays blank with hbr3.
This is still under investigation but in preparation for supporting
higher resolutions, its better to disable HBR3 till the issues are
root-caused as there is really no guarantee which monitors will show
the issue and which would not.
This can be enabled back after successful validation across more DP
sinks.

This is the equivalent of commit f5b4811e87 ("arm64: dts: qcom:
sc7180: Add trogdor eDP/touchscreen regulator off-on-time") and commit
23ff866987 ("arm64: dts: qcom: sc7180: Start the trogdor
eDP/touchscreen regulator on"), but for herobrine instead of trogdor.
The motivations for herobrine are the same as for trogdor.
NOTES:
* Currently for herobrine all boards are eDP, not MIPI. If/when we
have herobrine derivatives that are MIPI they we can evaluate
whether the same off-on-delay makes sense for them. For trogdor we
didn't add the delay to MIPI panels because the problem was found
late and nobody had complained about it. For herobrine defaulting to
assuming the same 500ms makes sense and if we find we need to
optimize later we can.
* Currently there are no oddball herobrine boards like homestar where
the panel really likes to be power cycled. If we have an oddball
board it will need to split the eDP and touchscreen rail anyway
(like homestar did) and we'll have to delete the "regulator-boot-on"
from that board.

The "pp3300_left_in_mlb" rail on herobrine eventually connects up to
"vreg_edp_3p3" on the qcard. On several herobrine designs this rail
has been measured to need more than 1ms to turn on.
While technically a herobrine derivative (defined as anyone including
the "herobrine.dtsi") could change the board to make the rail rise
faster or slower, the fact that two boards (evoker and villager) both
measured it as taking more than 1ms implies that it's probably going
to be the norm. Thus, let's add a "regulator-enable-ramp-delay"
straight into the herobrine.dtsi to handle this. If a particular
derivative board needs a faster or slower one then they can override
it, though that feels unlikely.
While we measured something a bit over 1ms, we'll choose 3ms to give
us a tiny bit of margin. This isn't a rail that turns off and on all
the time anyway and 3ms is nothing compared to the total amount of
time to power on a panel.

sc7280-herobrine based boards are specced to be able to access their
SPI flash at 50 MHz with the drive strength of the pins set at 8. The
drive strength is already set to 8 in "sc7280-herobrine.dtsi", so
let's bump up the clock. The matching firmware change for this is at:
https://review.coreboot.org/c/coreboot/+/63948
NOTE: the firmware change isn't _required_ to make the kernel work at
50 MHz, it merely shows that the boards are known to work fine at 50
MHz.
ALSO NOTE: this doesn't update the "sc7280-chrome-common.dtsi" file
which is used by both herobrine boards and IDP. At the moment the IDP
boards aren't configuring a drive strength of 8 and it seems safer to
just leave them at the slower speed if they're already working.

On herobrine boards the keyboard backlight is controlled through the
PWM LED driver. Currently both the PWM LED node and the node for the
keyboard backlight are disabled in sc7280-herobrine.dtsi, which
requires boards with a backlit keyboard to enable both nodes. There
are no other PWM LEDs on herobrine boards besides the keyboard
backlight, delete the 'disabled' status from the keyboard backlight
node, with that boards only have to enable the 'pwmleds' node for
keyboard backlight support.
Also add a label to the 'pwmleds' node to allow board files to refer to

Add eDP support to herobrine boards, splitting up amongst the
different files as makes sense. Rationale for the current split of
things:
* The eDP connector itself is on qcard. However, not all devices with
a qcard will use an eDP panel. Some might use MIPI and, presumably,
someone could build a device with qcard that had no display at all.
* The qcard provides a PWM for backlight that goes to the eDP
connector. This PWM is also provided to the board and it's expected
that it would be used as the backlight PWM even for herobrine
devices with MIPI displays.
* It's currently assumed that all herobrine boards will have some sort
of display, either MIPI or eDP (but not both).
* We will assume herobrine-rev1 has eDP. The schematics allow for a
MIPI panel to be hooked up but, aside from some testing, nobody is
doing this and most boards don't have all the parts stuffed for
it. The two panels would also share a PWM for backlight, which is
weird.
* herobrine-villager and herobrine-hoglin (crd) also have eDP.
* herobrine-hoglin (crd) has slightly different regulator setup for
the backlight. It's expected that this is unique to this board. See
comments in the dts file.
* There are some regulators that are defined in the qcard schematic
but provided by the board like "vreg_edp_bl" and
"vreg_edp_3p3". While we could put references to these regulators
straight in the qcard.dtsi file, this would force someone using
qcard that didn't provide those regulators to provide a dummy or do
an ugly /delete-node/. Instead, we'll add references in
herobrine.dtsi.

Having these pins with outputs is good on a fresh boot because it puts
the boot and reset pins in a known "good" state. Unfortunately, that
conflicts with the fingerprint firmware flashing code. The firmware
flashing process binds and unbinds the cros-ec and spidev drivers and
that reapplies the pin output values after the flashing code has
overridden the gpio values. This causes a problem because we try to put
the device into bootloader mode, bind the spidev driver and that
inadvertently puts it right back into normal boot mode, breaking the
flashing process.
Fix this by removing the outputs. We'll introduce a binding for
fingerprint cros-ec specifically to set the gpios properly via gpio APIs
during cros-ec driver probe instead.

While scoping signals, we found that the PCIe signals weren't
compliant at bootup. Specifically, the bootloader was setting up PCIe
and leaving it configured, then jumping to the kernel. The kernel was
turning off the regulator while leaving the PCIe clock running, which
was a violation.
In the regulator bindings (and the Linux kernel driver that uses
them), there's currently no way to specify that a GPIO-controlled
regulator should keep its state at bootup. You've got to pick either
"on" or "off". Let's switch it so that the PCIe regulator defaults to
"on" instead of "off". This should be a much safer way to go and
avoids the timing violation. The regulator will still be turned off
later if there are no users.

Not all herobrine boards have a world facing camera or a fingerprint
sensor, disable the regulators that feed these devices by default and
only enable them for the boards that use them.
Similarly the audio configuration can vary between boards, not all
boards have the regulator pp3300_codec, disable it by default.

Add nodes for the two SX9324 SAR proximity sensors. Not all herobrine
boards have these sensors, so leave them disabled by default.

This node should be named sar1-irq-odl, not sar0-irq-odl. Otherwise
we'll overwrite the settings for sar0 with what is intended for sar1,
leading to probe failures for sar1 that are quite confusing.

dtschema expects PWM node name to be a generic "pwm". This also matches
Devicetree specification requirements about generic node names.

Add the new herobrine-r1. Note that this is pretty much a re-design
compared to herobrine-r0 so we don't attempt any dtsi to share stuff
between them.
This patch attempts to define things at 3 levels:
1. The Qcard level. Herobrine includes a Qcard PCB and the Qcard PCB
is supposed to be the same (modulo stuffing options) across
multiple boards, so trying to define what's there hopefully makes
sense. NOTE that newer "CRD" boards from Qualcomm also use
Qcard. When support for CRD3 is added hopefully it can use the
Qcard include (and perhaps we should even evaluate it using
herobrine.dtsi?)
2. The herobrine "baseboard" level. Right now most stuff is here with
the exception of things that we _know_ will be different per
board. We know that not all boards will have the same set of eMMC,
nvme, and SD. We also know that the exact pin names are likely to
be different.
3. The actual "board" level, AKA herobrine-rev1.
NOTES:
- This boots to command prompt. We're still waiting on the PWM driver.
- This assumes LTE for now. Once it's clear how WiFi-only SKUs will
work we expect some small changes.

The upcoming herobrine-r1 board is really not very similar to
herobrine-r0. Let's get rid of the "herobrine.dtsi" file and stick all
the content in the -r0 dts file directly. We'll also rename the dts so
it's obvious that it's just for -r0.
While renaming, let's actually name the file so it's obvious that
"herobrine" is both the name of the board and the name of the
"baseboard". In other words "herobrine" is an actual board but also
often used as the name of a whole class of similar boards that forked
from a design. While "herobrine-herobrine" is a bit of mouthful it
makes it more obvious which things are part of an actual board rather
than the baseboard.
NOTE: herobrine-rev0's days are likely doomed and this device tree is
likely to be deleted in the future.

Herobrine is a Chrome OS board/platform based on the QCA SC7280.
Add a .dtsi for the platform parts and a .dts for the board
specific bits. Currently the .dtsi has everything except the
compatible strings, things will likely get shuffled around in the
future as we learn more about the differences between boards.
