[PATCH v1 2/3] iio:adc:ltc2471: add ltc2461/ltc2463 compatible strings

From: Darius Berghe
Date: Wed Jun 17 2020 - 09:33:06 EST


Add compatible strings for these devices in the existing ltc2471
driver.

The only difference between 2461/2463 and 2471/2473 is the output
rate of fixed 60sps and selectible 208/833sps respectively.

The driver does not implement changing the sampling rate so the
new devices are fully code comptible with this driver.
