Subject: Why doesn't W1 sub system support UART implementation as bus master?

Hi,

I was managed to implement battery driver based on W1 protocol.
Its master bus is implemented by UART port. The driver status is almost 
done.
And I plan to send patches for upstream.

Before that, I would like to know why it's not yet supported UART port 
as bus master.
Are there considerations on this? Anything do I miss?

PS. please loop me in the mail thread.

Cheers,
Matt
