Subject: [PATCH v5 0/3] iio: acpi_als: Add sotfware trigger support
Date: Mon, 28 Dec 2020 17:52:57 -0800 [thread overview]
Message-ID: <20201229015300.3037816-1-gwendal@chromium.org> (raw)
Some devices (chromebooks) present the ACPI ALS device but do not have
ability to notify when a new sample is present.
Add support for software trigger (hrtimer/sysfs-trigger) to allow
retrieving samples using iio buffers.
The first path fully adds timestamp channel, the second adds a local
variable in probe routine and the last one adds trigger support.
This patch assumes the patch "iio: set default trig->dev.parent" is
applied.
