Subject: dt-bindings:iio:dac:ti,dac5571 yaml conversion.
X-Git-Tag: io_uring-5.11-2020-12-23~73^2~52^2~66
X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=3eccfe575e00b9cdaed0600c079194b0be358ac9;p=linux-block.git

dt-bindings:iio:dac:ti,dac5571 yaml conversion.

A few tweaks in this conversion.
* The example didn't have the I2C address of 4C in the node name so
  fixed that.
* The reference voltage in the txt file is an optional binding, but
  the driver is making use of it to provide the scaling of the output
  channels.  As such I have made it required going forwards.
