misc: ad525x_dpot: Add support for SPI module device table matching

2011-11-18T19:27:02+00:00

Passing device name via platform data, is a leftover from times where
SPI module device table matching was not existent.

* Add id_table and remove old mechanism.
(To my knowledge no intree boards affected)
* Miscellaneous other cleanup.

ad525x_dpot: use correct rdac channel for ad5251/ad5252

2010-10-26T23:52:14+00:00

The ad5251/ad5252 devices have rdac1 and rdac3, but no rdac0.  So make
sure we use the right channels so userspace gets correct data and not just
garbage.

drivers/misc/ad525x_dpot.c: fix part name typos in defines

2010-10-26T23:52:14+00:00

There is no runtime effect by this change.  It frees up namespace for
defines erroneously used.  This is required to actually support devices
requiring the namespace, added with "drivers/misc/ad525x_dpot.c: new
features".

All defines touched have the same value defined, after the change.

ad525x_dpot: add support for SPI parts

2010-05-25T15:07:04+00:00

Split the bus logic out into separate files so that we can handle I2C and
SPI busses independently.  The new SPI bus logic brings in support for a
lot more parts:

	AD5160, AD5161, AD5162, AD5165, AD5200, AD5201, AD5203,
	AD5204, AD5206, AD5207, AD5231, AD5232, AD5233, AD5235,
