Subject: [PATCH v2 1/2] dt-bindings: iio: adc: ti,adc128s052: Add adc08c and adc10c family
Date: Sat, 21 Oct 2023 20:12:02 -0700	[thread overview]
Message-ID: <20231022031203.632153-2-sukrut.bellary@linux.com> (raw)
In-Reply-To: <20231022031203.632153-1-sukrut.bellary@linux.com>

The adcxx4s communicates with a host processor via an SPI/Microwire Bus
interface. The device family responds with 12-bit data, of which the LSB
bits are 0 for the lower resolution devices.
The unavailable bits are 0 in LSB.
Shift is calculated per resolution and used in scaling and
raw data read.

I have been able to test adc102s051,
hence adding just the missing ones in that family.

Lets reuse the binding to support the family of devices with name
ADC<bb><c>S<sss>, where
* bb is the resolution in number of bits (8, 10, 12)
* c is the number of channels (1, 2, 4, 8)
* sss is the maximum conversion speed (021 for 200 kSPS, 051 for 500 kSPS
and 101 for 1 MSPS)

Complete datasheets are available at TI's website here:
