From 4812a14a78c82cfe81cb5fd7555a9de723b49a59 Mon Sep 17 00:00:00 2001 From: Renato Lui Geh Date: Fri, 15 Mar 2019 23:14:27 -0300 Subject: [PATCH] staging:iio:ad7780: add chip ID values and mask The ad7780 supports both the ad778x and ad717x families. Each chip has a corresponding ID. This patch provides a mask for extracting ID values from the status bits and also macros for the correct values for the ad7170, ad7171, ad7780 and ad7781.
