2021-05-17dt-bindings:iio:dac:ti,dac082s085 yaml conversionJonathan Cameron2-34/+72
Fairly simple conversion with the exception of the XOR between spi-cpha and spi-cpol.

2021-05-17iio:accel:stk8312: Add lowercase i2c device idJonathan Cameron1-2/+4
These are never upper case. Chances are that all users of this driver were using the ACPI binding but just in case keep the uppercase version but mark it deprecated. Whilst here tidy up some spacing.

The device has a tsens-busy pin, but it's both fiddly and currently ignored by the Linux driver. Given it's not clear whether the binding should be an interrupt, or a GPIO I have left that out for now.
