Subject: [PATCH v2 0/3] novatek-nvt-ts: add support for NT36672A
 touchscreen

Extend the novatek touchscreen driver to support NT36672A chip which
is found in phones like Xiaomi Poco F1 [1]. Added devicetree support for
the driver and used i2c chip data to handle the variation in chip id and
wake type. Also added vcc and iovcc regulators which are used to power
the touchscreen hardware.
