[PATCH v9 2/4] dt-bindings: input: Add Cypress TT2100 touchscreen controller

There is a newer version of this series
[PATCH v9 2/4] dt-bindings: input: Add Cypress TT2100 touchscreen controller
Posted by Alistair Francis 3 years, 5 months ago 
Add the Cypress TrueTouch Generation 5 touchscreen device tree bindings
documentation. It can use I2C or SPI bus.
This touchscreen can handle some defined zone that are designed and
sent as button. To be able to customize the keycode sent, the
"linux,code" property in a "button" sub-node can be used.

Hi,

this should go in, I am tired of carrying it around...
to make the bot happy, the following things need to be changed.

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/patch/

This check can fail if there are any dependencies. The base for a patch
series is generally the most recent rc1.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit.
