Subject: [PATCH v4 4/9] staging:iio:ad7780: add chip ID values and mask
Date: Thu, 28 Feb 2019 11:24:55 -0300 [thread overview]
Message-ID: <90c573cd53bb54d49de6ac270bcff66880ccfeb5.1551358569.git.renatogeh@gmail.com> (raw)
In-Reply-To: <cover.1551358569.git.renatogeh@gmail.com>
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.
