Input: goodix - add GT5663 CTP support
[ Upstream commit a5f50c501321249d67611353dde6d68d48c5b959 ] 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 Signed-off-by: Jagan Teki <jagan@amarulasolutions.com> Reviewed-by: Rob Herring <robh@kernel.org> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com> Signed-off-by: Sasha Levin <sashal@kernel.org>
