Subject: [PATCH v4 1/4] dt-bindings: i2c: imx-lpi2c: Add properties and use unevaluatedProperties
Date: Thu, 17 Sep 2020 21:13:18 +0200 [thread overview]
Message-ID: <20200917191321.28741-1-krzk@kernel.org> (raw)
Additional properties actually might appear (e.g. power-domains) so
describe all typical properties, reference generic i2c schema and use
unevaluatedProperties to fix dtbs_check warnings like:
arch/arm64/boot/dts/freescale/imx8qxp-ai_ml.dt.yaml: i2c@5a800000:
'assigned-clock-rates', 'assigned-clocks', 'clock-names', 'power-domains' do not match any of the regexes: 'pinctrl-[0-9]+'
arch/arm64/boot/dts/freescale/imx8qxp-colibri-eval-v3.dt.yaml: i2c@5a800000:
'touchscreen@2c' does not match any of the regexes: 'pinctrl-[0-9]+'
Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org>
---
Changes since v3:
1. Drop address/size cells
2. Set maxItems to power domains to 1
Changes since v2:
1. Add assigned-clock-parents
Changes since v1:
1. Add more properties and include /schemas/i2c/i2c-controller.yaml#
