Subject: [PATCH] Input: goodix - support gt9147 touchpanel

From: Yannick Fertré <yannick.fertre@...com>

Add support for it by adding compatible and supported chip data
(default settings used).
The chip data on GT9147 is similar to GT912, like
- config data register has 0x8047 address
- config data register max len is 240
- config data checksum has 8-bit
