Hi Krzyztof,

Apologies !

Do you mean to send the DTS just to linux-arm-msm list and not linux-usb 
list ? I don't think it was posted on this series and I am not on 
linux-arm-msm mailing list, so missed that comment. Sorry for that. I 
saw some series where DT, Driver and bindings were sent as one set to 
linux-usb list as well and so wanted to follow suite. Will make sure to 
send DT just to linux-arm-msm list from now on. Thanks for the comments :-)

Krishna,
