[PATCH 0/4] Convert STM32 Timer mdf bindings to yaml

[PATCH 0/4] Convert STM32 Timer mdf bindings to yaml

[Benjamin Gaignard]

This series converts STM32 Timer mfd bindings to json-schema.
The original binding split between all the subnode remains the same
that why subnode bindings are converted first and then included in
the mfd binding.

Benjamin Gaignard (4):
  dt-bindings: counter: Convert stm32 counter bindings to json-schema
  dt-bindings: iio: timer: Convert stm32 IIO trigger bindings to
    json-schema
  dt-bindings: pwm: Convert stm32 pwm bindings to json-schema
  dt-bindings: mfd: Convert stm32 timers bindings to json-schema

Also, checkpatch reports trailing whitespace in several of your patches.

I will write all in one file and fix trailing whitespace in v2

I'm far from great on these as still haven't taken the time I should to learn
the yaml syntax properly.  A few comments inline however based mostly on this
doesn't quite look like other ones I've seen recently.

I can't put "description" on this field because the syntax doesn't allow it.
I will add a comment in v2 to explain what reg is.

No, $nodename is correct. The '$' signifies something we generate and 
add in. IOW, not a real property. I guess we could have used 'name' here 
and stuck with traditional OpenFirmware.

No, $nodename is correct. You don't have a choice. That is what the

-This IP provides 3 types of timer along with PWM functionality:
-- advanced-control timers consist of a 16-bit auto-reload counter driven by a programmable

-- general-purpose timers consist of a 16-bit or 32-bit auto-reload counter driven by a
-  programmable prescaler and PWM outputs.
-- basic timers consist of a 16-bit auto-reload counter driven by a programmable prescaler.
-
-Required parameters:
-- compatible: must be "st,stm32-timers"

-- reg:			Physical base address and length of the controller's

-- dmas:			List of phandle to dma channels that can be used for

This works, but I prefer the child node names be listed under properties 
here with a ref:

counter:
  $ref: "../counter/st,stm32-timer-cnt.yaml#"

from 0 up to 8, but I don't know the syntax for that. minItems = 0 isn't 
accepted.

Any hints for me ?

it could be ch1 ... ch8, "trig" or "up" in any order.

Again I haven't be able to find a syntax that allow to list the names 
and use them in any orders.

0 is not accepted because the property is never 0 items. 0 is not
present. So just:

minItems: 1
maxItems: 8

Why does it need to be in any order? Normally we don't want to have that.

dma-names:
  items:
    enum: [ ch1, ch2, ..., trig, up ]
