Subject: [PATCH v9 07/55] Input: atmel_mxt_ts - implement T9 vector/orientation support
Date: Wed, 25 Mar 2020 06:32:46 -0700
Message-ID: <20200325133334.19346-8-jiada_wang@mentor.com> (raw)
In-Reply-To: <20200325133334.19346-1-jiada_wang@mentor.com>

From: Nick Dyer <nick.dyer@itdev.co.uk>

The atmel touch messages contain orientation information as a byte in a
packed format which can be passed straight on to Android if the input
device configuration is correct.

This requires vector reports to be enabled in maXTouch config (zero
DISVECT bit 3 in T9 CTRL field)

Android converts the format in InputReader.cpp, search for
ORIENTATION_CALIBRATION_VECTOR.
