Nit: as the context below hints at, the company call themselves
"FriendlyElec" these days - certainly since long before this board
existed - so for consistency we should probably use that name in the
description (but keep the established vendor prefix).

Neat! Mine turned up last week (far earlier than expected, yay!), and I
was going to do some DT hacking, but here it is already :)

This is "vcc_io_sd" per the schematic.

Strictly the supply here is vdd_5v - vcc_io is only driving the bias
circuitry for the regulator adjustment.

This seems to match the schematic, however in practice the GPIO seems to
have a mind of its own and not respond to the LED settings - are we
missing something with the pinctrl perhaps?

Does this need to be polled? I would have thought regular
interrupt-based gpio-keys should work, to avoid the overhead of polling
for something (relatively) incredibly rare, but perhaps I'm wrong :/

Is this needed over and above the txpbl fix present in the main DTSI? I
forget exactly where all those discussions ended up, but if it matters
here then it probably matters for all RK3328 boards.

Since you're describing the phy already, you can convert these to
generic reset specifiers on the phy node itself (shame we don't have an
interrupt wired up, oh well...)

Is that right? The schematic says the phy is strapped for address 1
(although 0 probably does manage to work since it should be interpreted
as a broadcast address).

The schematic says GPIO1_D0 for this.

It shouldn't hurt to enable PWM2 from the outset to make mucking about

How about UHS modes, since we have the requisite I/O voltage support?

I believe this property is only meant for full-size MMC/SD sockets where
write-protect functionality is expected but somehow broken. For micro-SD
sockets the SoC pin should be hard-wired to write-enable anyway and thus
it shouldn't need to be stated.

No reason not to enable the OTG port either - I've hacked that in with
g_serial for a cheeky console while powering the board from my laptop
and it works fine.

Hi Robin,
thanks for your review. Only adressing some non-formal comments below.

Hmm, this is strange. It works fine on my unit (with the current OpenWrt release). Can you test this and report back?

To be honest, I've missed that this is still polled. I've had this set to polled mode, as I've
had some issues (were to dumb) to get the pinmux going. I'll switch this to interrupt triggered and report back.

It seems to matter, as otherwise forwards from LAN to WAN will result in tx_fifo errors.

Yup, I've forgotten that there's reset-gpio bindings for the PHY itself.

Thanks for this explanation, I'll remove and re-test.

Ouch, I've completely missed the micro-USB port is wired up to the OTG port.
I'll follow up with a v3 in the coming days. Thanks for your feedback!

It seems like somehow that particular GPIO doesn't get configured
properly and is still in its default out-of-reset state as an input.
Poking the GPIO from sysfs works as expected, and in fact just unbinding
and rebinding the leds-gpio driver also manages to kick things into
shape. Clearly there's some subtle driver-level issue, but at least it's
not a DT problem :)

On second look it's already present in half the existing RK3328 DTs
(including the one I wrote, ahem...), so probably does deserve promoting
into the DTSI.

Yeah, mine came with the version 2 heatsink/fan fitted, although upon
investigation it turns out the PWM is next to useless (something's off
with rise times in the external MOSFET switching setup) and the fan
connector may as well just be treated as GPIO-controlled anyway.

FWIW SDR104 seems to be working fine for me, with the PMIC interrupt
corrected so as not to break the regulator.

Actually I think I was mistaken there - having double-checked the
binding definition and datasheet it looks like RK3328 doesn't expose the
WP function on any pin at all, so by the letter of the binding this
*should* be specified for correctness (since we don't necessarily know
for sure that the controller's internal WP line isn't left floating).
Sorry for the confusion.
Cheers,
Robin.

This label shows up in the kernel tree.
User space scripts don't like a space in a dir name for example.
Users don't like typing mixed SHIFT-capitals.

But yes, since the early Chromebook project in 2014 we agreed on
doing in Rockchip dts files:

kever.yang, m.reichl, t.schramm, pgwipeout, devicetree,
linux-arm-kernel, linux-rockchip
This adds support for the NanoPi R2S from FriendlyARM.
Rockchip RK3328 SoC
1GB DDR4 RAM
Gigabit Ethernet (WAN)
Gigabit Ethernet (USB3) (LAN)
USB 2.0 Host Port
MicroSD slot
Reset button
WAN - LAN - SYS LED

Changes in v2:
- Change model name to FriendlyElec
- Enable SD UHS modes
- Add startup delay to SDIO regulator to improve
issues reported with some cards
- Fix PMIC interrupt pin
- Add pinctrl node for ethernet-PHY
- Fix various formatting issues
