Subject: [PATCH v1 07/63] Input: atmel_mxt_ts - implement T9 vector/orientation support
Date: Fri, 16 Aug 2019 17:30:34 +0900 [thread overview]
Message-ID: <20190816083130.18250-3-jiada_wang@mentor.com> (raw)
In-Reply-To: <20190816083130.18250-1-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.
