Subject: [PATCH v3 0/2] mips: dts: ralink: Add support for TP-Link HC220 G5 v1 board

Add device tree and bindings for the TP-Link HC220 G5 v1 wireless AP,
a consumer product from TP-Link based on MT7621.

Changes since v2:
- Remove WIP nodes for NAND flash that accidentally got included in v2
- Fix commit message with the actual 5GHz WiFi chip name
- Remove gmac and mdio nodes from device tree as defaults are sufficient
- Added sub-nodes under pcie for each of the WiFi chip with appropriate
compatible string.
- Collect Acks received for the device tree bindings patch

Changes since v1:
- Changed compatible for the board to "tplink,hc220-g5-v1"
- Updated the DSA switch nodes to better reflect actual usage.
- Disabled the fixed-link in gmac1
- Added device tree bindings in Documentation/

v2: https://lore.kernel.org/linux-mips/[email protected]/
v1: https://lore.kernel.org/linux-mips/[email protected]/

Subject: [PATCH v3 1/2] mips: dts: ralink: Add support for TP-Link HC220 G5 v1 board

This WiFi AP is based on a MT7621 SoC with 128MiB RAM, 128MiB NAND,
a MT7603 2.4GHz WiFi and a MT7613 5GHz WiFi chips integrated on the board,
connected to the main SoC over PCIe.

The device uses NMBM over NAND, which is not currently supported in the
mainline, so NAND node is skipped in this revision.

Please use 8 digit addressing for the memory start and size offsets:

0x00000000 0x08000000

Usually the led name would point to the component the LED is used for.

Is there a specific reason you're using leds/common.h,
color & function instead of 'label = "red:ledname"'?

Every led node needs the "led-" prefix to satisfy the leds-gpio.yaml
schema. You can check for dt-schema warnings using this command:

ARCH=mips make clean dtbs_check

Ignore the warning for mediatek,mt7621-eth.

Both radios work with this then?

Also, I see a bunch of warnings now that the mediatek,mt76 compatible
string is added. The warning from schemas/pci/pci-bus.yaml is concerning.

Rob, Krzysztof any ideas what to do? The PCI child node is supposed to
be the properties of the wireless device. But the compatible string
doesn't match the schema on schemas/pci/pci-bus.yaml.

compatible:
contains:
pattern: "^(pci[0-9a-f]{3,4},[0-9a-f]{1,4}|pciclass,[0-9a-f]{4,6})$"

Liviu, in the meantime, you should submit this patch without this
compatible string. I will handle this issue.

These are "generic" LEDs controlled from the userspace. The original firmware
uses GREEN for normal operations, RED for faults and BLUE for when WPS is
enabled. I'm not sure if there are any standard bindings that I can use here.

I actually can't remember why I've created them this way. I might've been
under the impression that giving them standard colour names will make it
easier for userspace to identify and use them, but as I haven't yet
investigated into how I'm going to use the device I'm unaware of any
userspace requirements. It's possible OpenWRT or LEDE have some strong
definitions, but I'm not aware of them as I don't use any of the distros.

Yes, they work with and without the compatible property.

TBH, I've always found the attempts to add device tree nodes for PCI(e) devices
amusing. The bus is supposed to be queried and one can learn from device ID
what hardware they're talking to. But then you need device tree (or ACPI for x86_64)
to layer on top of that information about where EEPROM data might be, and other
metadata that blurs the "DT describes the hardware" line (you could technically
reformat the NAND and place the EEPROM data somewhere else on this platform).

OK, I will drop the compatible strings from v4.

Thanks for the quick review!

Looking at:

https://www.kernel.org/doc/html/latest/leds/leds-class.html#led-device-naming

You could use red:fault, green:power, and blue:wps. For node names,
led-fault, led-power, and led-wps.

Without making any changes in the device tree, because of the use of 'function' property,
I get this:

# ls -al /sys/class/leds/
drwxr-xr-x 2 root root 0 Jun 6 14:24 .
drwxr-xr-x 37 root root 0 Jan 1 1970 ..
lrwxrwxrwx 1 root root 0 Jun 6 14:24 blue:wps -> ../../devices/platform/leds/leds/blue:wps
lrwxrwxrwx 1 root root 0 Jun 6 14:24 green:power -> ../../devices/platform/leds/leds/green:power
lrwxrwxrwx 1 root root 0 Jun 6 14:24 red:fault -> ../../devices/platform/leds/leds/red:fault

May I suggest that I change only the node names and not add a label, keeping the 'function' property instead?

Best regards,
Liviu

It seems to achieve the same result so, sure.
