This seems a little strange to me, though, admittedly, I've never worked
with these types of bridges before, so I may be misunderstanding this. I
was under the impression that we could obtain the panel by traversing an
OF graph, so that we didn't have to have that extra nvidia,panel
property. As it is, you seem to describe two different paths, one that
goes from the RGB output to the panel directly, and another that goes
from the RGB output to the LVDS encoder and then to the panel.

It doesn't seem to me like a direct link from RGB output to panel does
actually exist in this setup.

I don't see power-supply defined as a property for the PWM controller.
Why do you need this?

Are these clocks going to the PMIC and RTC, or are they generated by the
chips? If they are generated by the chips, which sounds like they might
be, wouldn't it be better to represent them as children of the
corresponding chips?

There's probably no infrastructure to do this, so maybe that would be
overkill. But for clarity it might be worth documenting here where
exactly these clocks come from.

I don't think unit-addresses are supposed to be freeform text like
above. These should always reflect the value of the "reg" property,
though in this case we don't have one...

> +			nvidia,ram-code = <0>;

In retrospect it might have been better to just reuse the reg property
for this.

I think in this case it might be best to reflect the RAM code in the
unit-address. At least that way we conceptually get things right since
it's the RAM code that selects which of these tables is used, much like
a register, I2C slave address, or SPI chip select would select which of
the subdevices are targetted.

AFAIK, the direct link doesn't exist on any of Tegra boards, they all
have an LVDS bridge. The older device-trees just didn't model it properly.

The LVDS bridge and panel-lvds are relatively new things in DRM, which
allow to model hardware more correctly, like for example the bridge's
powerdown control is now modeled properly.

The nvidia,panel is a mandatory property for the Tegra's DRM output,
panel won't light up without it. I guess it should be possible to get
the panel's phandle from the graph, but this is not supported by the
Tegra's DRM driver + nvidia,panel is also useful to have for older
kernels that do not support panel-lvds. The panel falls back to a
simple-panel in the case of older kernel version, which results in a not
entirely appropriate panel timing (wrong framerate), but this is okay'ish.

Yes, looks like it's not needed. I'll remove it in v3, thanks.

The dtbs_check doesn't complain, should be fine :)

But I don't mind, although the camel-case should be a correct way of
spelling WiFi. I'll change it in v3.

They are generated by the chips.

The PMIC has a built-in 32K oscillator.

The kk3270032 is a dedicated onboard 32K oscillator. This one is not
mandatory to model in the device-tree, but I wanted to model as much as
possible.

Yes, PMIC doesn't model the clock. All Tegra boards model the PMIC's
clock this way, although those boards don't set the clock-output-names
property, which makes the DT model more obscure than it could be.

The kk3270032 is a standalone oscillator, so it's fine as-is already.

I guess the output clock-output-names are already self-explanatory,
don't you think so? For more details you could always consult the
board's schematics.

This could be done, although we already have a precedent in a form of
the paz00 board that got memory timings not so long time ago.

I'll change it in v3.

Thank you for the review.
