From e359a29225dde53fade5fa4bc3d957599fb5f9a5 Mon Sep 17 00:00:00 2001 From: Alexandru Ardelean Date: Fri, 17 May 2019 18:44:41 +0300 Subject: dt-bindings: iio: accel: adxl345: switch to YAML bindings 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.
