Subject: [PATCH][V3] dt-bindings: iio: accel: adxl345: switch to YAML bindings
Date: Fri, 17 May 2019 18:44:41 +0300 [thread overview]
Message-ID: <20190517154441.27080-1-ardeleanalex@gmail.com> (raw)
In-Reply-To: <20190516133609.10975-1-alexandru.ardelean@analog.com>
From: Alexandru Ardelean <alexandru.ardelean@analog.com>
The ADX345 supports both I2C & SPI bindings.
This change switches from old text bindings, to YAML bindings, and also
tries to make use of the recent multiple-examples support.
Signed-off-by: Alexandru Ardelean <alexandru.ardelean@analog.com>

Changelog v1 -> v2:
* dropped interrupt-parent from DT, as suggested by Rob
Changelog v2 -> v3:
* add Rob's Reviewed-by tag
* add YAML file to MAINTAINERS - main reason for this V3
