[galak]

@erwango not sure if this is worth deal with now, or if things will change when we add proper pinctrl/mux support to DT and zephyr

[erwango]

Warning detected when using dtc v1.4.2. I propose to address these for pinctrl API introduction which will require rework of this nodes

[pfalcon]

Another DTS warning: https://github.com/zephyrproject-rtos/zephyr/issues/7155

[erwango]

Being fixed with #7168

[erwango]

Looking to the warnings, I think one of them is abusive, and I propose to derogate: "Node [...] has a unit name, but no reg property" ePAPR 1.1 section 2.2.1.1 "Node Name Requirements" specifies that any node that has a reg property must include a unit address in its name with value matching the first entry in its reg property. Conversely, if a node does not have a reg property, the node name must not include a unit address.

usart1_pins_a: usart1@0 {
    rx_tx {
        rx = <STM32_PIN_PB7 (STM32_PINMUX_ALT_FUNC_7 | STM32_PUPDR_NO_PULL)>;
        tx = <STM32_PIN_PB6 (STM32_PINMUX_ALT_FUNC_7 | STM32_PUSHPULL_NOPULL)>;
    };
};

According to the rule, unit name usart1@0 should be used only if node a reg property. If we want to conform to this rule, there are 2 options:

• add a reg property to the node, it will looks like:

  usart1_pins_a: usart1@0 {
      reg = <0>;
  rx_tx {
      rx = <STM32_PIN_PB7 (STM32_PINMUX_ALT_FUNC_7 | STM32_PUPDR_NO_PULL)>;
      tx = <STM32_PIN_PB6 (STM32_PINMUX_ALT_FUNC_7 | STM32_PUSHPULL_NOPULL)>;
  };
  };

  But reg property is not pertinent to describe a pin or led node.

• loose phandle associated to the node. This is a pity since phandle are quite handy for many operations like assignments or aliases. For instance, instead of:

  led0 = &green_led_4;
  pinctrl-0 = <&usart2_pins_d>;

  we'll have to use:

  led0 = "/leds/green_4";
  pinctrl-0 = "/soc/pin-controller@4200000/usart2_pins_d";

As mentioned in #7168, some of these warnings are also present in STM32 Linux dts files, but associated warning do not show up. I've not been able to confirm, but I assume dtc is ran with -q (quiet) option to silent warnings.

I propose to derogate to this rule and use same option (dtc -q) in in zephyr.

According to the rule, unit name usart1@0 should be used only if node a reg property. If we want to conform to this rule, there are 2 options:

what does linux dt do here, does it use something like @0?

What's the warning we get for this case?

Yes, exact same syntax

What's the warning we get for this case?

stm32l496g_disco.dts_compiled: Warning (unit_address_vs_reg): Node /soc/pin-controller/usart1@0 has a unit name, but no reg property

Side note: Using alias syntax such as led0 = "/leds/green_4"; requires slight update of extract dts_include script. Using pinctrl-0 = "/soc/pin-controller@4200000/usart2_pins_d"; seems to have a deeper impact (devicetree.py as first sight).

Confused, I was asking about the phandle issue. What warning do we get related for that.

[nashif]

@galak is this still an issue?

Closing this now, we have a few dtc warnings, but most aren't related STM32 anymore. Will open an new issue for the dtc warnings we do have.
