Only the actual hardware access is different. The spi protocol is different enough to not be able to map the differences via a regmap. Also generalize the entry in MAINTAINER to cover the newly introduced file.

Initially I named the generic part ltc249x, but wild card names are frowned upon, so the generic part is called ltc2497-core even though it's not obvious that this is then to be reused for the ltc2496 driver.

The AB8500 GPADC can convert 10 different channels and these are used for monitoring voltages in the U8500 chipset, some are used for battery charging, some for temperature monitoring. As this is very core functionality that a lot of drivers depend on and was formerly compiled in with the AB8500 core driver, we deafault it to 'y' in Kconfig: it can be compiled out but it is really not advisible: the platform can for example overheat if we do.

The ad7780 is a sigma-delta analog to digital converter. This driver provides reading voltage values and status bits from both the ad778x and ad717x series. Its interface also allows writing on the FILTER and GAIN GPIO pins on the ad778x.
