Subject: [PATCH v8 3/5] ARM: dts: stm32: Fix schema warnings for pwm-leds
Date: Sat, 28 Nov 2020 22:53:51 +0100	[thread overview]
Message-ID: <20201128215353.3991-4-post@lespocky.de> (raw)
In-Reply-To: <20201128215353.3991-1-post@lespocky.de>

The node names for devices using the pwm-leds driver follow a certain
naming scheme (now).  Parent node name is not enforced, but recommended
by DT project.

  DTC     arch/arm/boot/dts/stm32mp157c-lxa-mc1.dt.yaml
  CHECK   arch/arm/boot/dts/stm32mp157c-lxa-mc1.dt.yaml
/home/alex/build/linux/arch/arm/boot/dts/stm32mp157c-lxa-mc1.dt.yaml: led-rgb: 'led-blue', 'led-green', 'led-red' do not match any of the regexes: '^led(-[0-9a-f]+)?$', 'pinctrl-[0-9]+'
        From schema: /home/alex/src/linux/leds/Documentation/devicetree/bindings/leds/leds-pwm.yaml

Notes:
    v7 -> v8:
      * rebased on v5.10-rc1
      * updated indexes and added comment (Ahmad Fatoum)
    
    v6 -> v7:
      * split up patch (one per sub arch)
      * added actual warnings to commit message
