From bd690dfab1e74b0684ef236826c16dd2375cb948 Mon Sep 17 00:00:00 2001 From: Jonathan Cameron Date: Sat, 31 Oct 2020 18:12:39 +0000 Subject: dt-bindings:iio:adc:maxim,max1027: Pull out to separate binding doc. The afe/voltage-divider.yaml example uses this device with 2 properties not provided by trivial-devices.yaml (spi-max-frequency and #io-channel-cells) Solve that by creating a more specific binding doc.
