Subject: Re: [PATCH v2 1/5] dt-bindings: input: touchscreen: add bindings for
 focaltech,fts5452

Hi Krzysztof Kozlowski,

Konrad Dybcio suggested to use interrupts-extended instead interrupts.
So in my WIP v3, I have updated it in the dts and bindings example.
However, I am confused if I should replace the "interrupts" with
"interrupts-extended" property in the schema too? I see a lot of schemas
specifying "interrupts", with examples using "interrupts" or
"interrupts-extended". At the same time, I see some specifying both
"interrupts" and "interrupts-extended" (like one of these two) and very
few others specify only "interrupts-extended" in the schema. Which is
the currently recommended way to do this?

In between, the interrupt property should be a required property as the
driver will not function without an interrupt. I will fix that in v3.

Thanks,
Joel Selvaraj
