[PATCH v2 22/41] ARM: s3c: adc: move header to linux/soc/samsung

Krzysztof Kozlowski
2020-08-06T18:40:44Z

There are multiple drivers using the private adc interface.
It seems unlikely that they would ever get converted to iio,
so make the current state official by making the header file
global.

The s3c2410_ts driver needs a couple of register definitions
as well.
