I'll remove SoC features, as it's easy to find and it's not needed in
commit message anyway. Instead I'll describe which features (nodes)
are added in DT by this commit.

This device is not available for purchase yet. I'll send the patch for
board dts once it's announced. I can do all the testing for now, if
you have any specific requests. Would it be possible for us to review
and apply only SoC support for now? Will send v2 soon...

Fixed. You are right, irq_domain_xlate_twocell() is used in
pinctrl-exynos.c. Btw, that fixed the use-case when gpX is specified
as interrupt-parrent for other nodes.

Done, thanks.

Yes, replaced pin-pud values with these constants, thanks. Won't touch
pin-drv properties, though, as different domains have different
meanings for the same values, so don't want to introduce the whole
bunch of consts.

decon* nodes seem like leftover from vendor kernel. Those are not
connected anywhere on my board, so I removed those nodes.
Also fixed node names as you suggested, and fixed all stuff found with
W=1 build, thanks for reminding me that.

Done. Also rearranged the nodes in that way for other pinctrl domains.

Yeah, unfortunately this confusing I2C naming (CAM_PMIC_I2C and
MOTOR_I2C) actually comes from TRM and SoC schematic symbol. So in
Device Tree it's called just i2c5 and i2c6 (because it's a regular I2C
really), but in TRM it's a mix of both names. I guess it's just a poor
pin function naming, done by SoC designers.
That said, I suggest changing these comments to something like this:
/* I2C5 (also called CAM_PMIC_I2C in TRM) */
/* I2C6 (also called MOTOR_I2C in TRM) */

> Comment seems to duplicate node name/label.

I think the comment is useful, maybe just designed poorly. It's
pointing out that this HS-I2C block is based on USI IP-core. Basically
we have 7 USI blocks in this SoC:
- 5 USIs that pre-defined: HSI2C0, HSI2C1, HSI2C2, UART0 and SPI0;
although AFAIU they can be changed via System Register as well, but
seems like nobody does that
- 2 USIs from CMGP blocks (CMGP0 and CMGP1), which are actually configurable
I will revise all such comments like this, just to show those blocks
are based on USI design:
/* USI: HSI2C0 */
At least when I was bringing up this board, I was really confused for
long time about this USI business. So I'm sure some kind of comments
might be actually helpful. And that's one reason to keep
exynos850-usi.dtsi file: although I removed it for now, squashing it
into exynos850.dtsi, I think it might be a good idea to bring that
back once all USI nodes are described. Just thinking aloud :)

> No, seriously. What sensor is it? In SoC?
>
In this context, "sensor" stands for "camera". Of course, it resides
(or rather *may* reside) outside of the SoC. This is just useful pin
configuration for camera master clock lines (3 of them). On schematic
those 3 lines are grouped into "MCLK" block, and those pins main
function is CAM_MCLK. I guess it makes sense to keep those
definitions, as I doubt somebody would actually consider using those
lines for somthing else. Or I can remove all those sensor*
definitions, if you'd like, then those can be added later, when camera
support cames in.

Yeah, you're right. As it's only serial_0 for now, I've moved that

It actually doesn't, though it does complain about other undocumented
compatibles. I understand that it should be documented in
samsung-boards.yaml, but is it ok with you if I do that later, when
adding some actual board's dts? Just don't want to have two patches
for that.

Well, I didn't implement that from scratch :) As you probably figured,
I reworked the vendor's dts (heavily, that is). But yeah, I definitely
re-checked with existing DTs this time (exynos5433 and exynos7
mostly), and tried to follow best practices.
