Subject: [PATCH 2/2] Input: edt-ft5x06 - add support for polled configuration
Date: Tue, 30 Apr 2019 20:58:59 +0200 [thread overview]
Message-ID: <20190430185859.24015-2-nsaenzjulienne@suse.de> (raw)
In-Reply-To: <20190430185859.24015-1-nsaenzjulienne@suse.de>
Some devices might not provide an interrupt line for the touchscreen.
In that case the driver defaults to using a polled interface.
