Hi Dmitry,
This change is used to enable pwrkey, volume-up and volume-down 
function, and the gpio-keys configuration is used to enable volume-up.

So can I update the commit message as below:

arm64: dts: qcom: qcm6490-idp: enable pwrkey and volume-up/down function

Add configurations to enable pwrkey, volume-up and volume-down function.

Thanks,
Hui
