Subject: [PATCH 2/5] mfd: sunxi-gpadc-mfd: add buffer structure
Date: Wed, 20 Jul 2016 10:29:08 +0200 [thread overview]
Message-ID: <1469003351-15263-3-git-send-email-quentin.schulz@free-electrons.com> (raw)
In-Reply-To: <1469003351-15263-1-git-send-email-quentin.schulz@free-electrons.com>
This adds a buffer structure for files including the sunxi-gpadc-mfd
header. This structure has a buffer of 32 u32 values to store data from the
FIFO of the GPADC of Allwinner SoCs. A buff_size is provided in case the
buffer is not full.
