Subject: [PATCH v4 4/4] Input: goodix - Add GT5663 CTP support
Date: Tue, 12 Feb 2019 16:54:39 +0530	[thread overview]
Message-ID: <20190212112439.2025-5-jagan@amarulasolutions.com> (raw)
In-Reply-To: <20190212112439.2025-1-jagan@amarulasolutions.com>

GT5663 is capacitive touch controller with customized smart
wakeup gestures.

Add support for it by adding compatible and supported chip data.

The chip data on GT5663 is similar to GT1151, like
- config data register has 0x8050 address
- config data register max len is 240
- config data checksum has 16-bit
