Subject: [PATCH v4 3/9] staging: iio: ad7780: set pattern values and masks directly
Date: Thu, 28 Feb 2019 11:24:32 -0300 [thread overview]
Message-ID: <9c8331166124ec2bd52794a9c9f844bfb70d1cd9.1551358569.git.renatogeh@gmail.com> (raw)
In-Reply-To: <cover.1551358569.git.renatogeh@gmail.com>
The AD7780 driver contains status pattern bits designed for checking
whether serial transfers have been correctly performed. Pattern macros
were previously generated through bit fields. This patch sets good
pattern values directly and masks through GENMASK.
