Subject: [PATCH 6/7] Input: cyttsp - Set abs params for ABS_MT_TOUCH_MAJOR
Date: Tue, 30 Mar 2021 10:54:23 +0200	[thread overview]
Message-ID: <20210330085424.2244653-7-linus.walleij@linaro.org> (raw)
In-Reply-To: <20210330085424.2244653-1-linus.walleij@linaro.org>

The driver is certainly reporting pressure in
cyttsp_report_tchdata() with
input_report_abs(input, ABS_MT_TOUCH_MAJOR, tch->z);
so we should also advertise this capability.
