[PATCH v5 0/3] novatek-nvt-ts: add support for NT36672A touchscreen

[Joel Selvaraj via B4 Relay]

Extend the novatek touchscreen driver to support NT36672A chip which
is found in phones like qcom/sdm845-xiaomi-beryllium-tianma.dts.
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.
