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)

You have checkpatch warnings.

My ACK was given with conditional - PASSING checkpatch.

Does it pass? No. Don't add tags if you do not fulfill the criteria.

Drop the tag.

Best regards,
Krzysztof

Thanks for the review.
Sorry about that. while rearraging the commit message, it slipped beyond
75 chars limit.
I will fix this in v5 and will use the tag with no checkpatch warnings.
