Subject: [PATCH v2 2/3] iio: hid-sensor-als: Add relative hysteresis support
Date: Sun,  7 Feb 2021 15:00:47 +0800	[thread overview]
Message-ID: <20210207070048.23935-3-xiang.ye@intel.com> (raw)
In-Reply-To: <20210207070048.23935-1-xiang.ye@intel.com>

Hid sensor als use relative hysteresis, this patch adds the support.
