Subject: [PATCH v3 08/20] staging:iio:adc:ad7280a: Drop unused timestamp channel.
Date: Sun,  6 Feb 2022 19:03:16 +0000	[thread overview]
Message-ID: <20220206190328.333093-9-jic23@kernel.org> (raw)
In-Reply-To: <20220206190328.333093-1-jic23@kernel.org>

From: Jonathan Cameron <Jonathan.Cameron@huawei.com>

The driver doesn't support buffered mode, so a timestamp channel that
is entirely hidden from userspace without buffer mode is rather pointless.
Drop it.
