e170adcb40 ARM: S3C: Add ADC synchronous read call.
To add HWMON support, we need a synchronous read() call that blocks
until completion. Add the client that is being service to the select
and convert callbacks to make the code easier.

3f7ea467be [ARM] S3C: ADC: Expose number of remaining conversions to
convert callback

This patch allow us to efficiently modify the number of
remaining conversions from the client side. This us useful
when we do not know in advance how many conversions we will
need or when we need to cancel pending conversions.

This change is simple enough to be compatible with existing
code that can just define the new pointer in the callback
and ignore it.

Sample usage:

28ab44c5be [ARM] S3C24XX: ADC driver core
A common core driver for the S3C24XX ADC block so that
the touchscreen, hwmon and any other drivers can share
the resource.
