Hi,

Add a suitable sleep configuration for uart3 to support Bluetooth wakeup.

If QUP function is selected in sleep state, UART RTS/RFR is pulled high
during suspend and BT SoC not able to send wakeup bytes. So, configure
GPIO mode in sleep state to keep it low during suspend.

Note: I can't find this email on any of the mailing lists.  Can you
check your config?  I tried:

http://lore.kernel.org/r/1599742438-16811-4-git-send-email-skakit@xxxxxxxxxxxxxx

...and also checked patchwork servers.  I only see patch 1 and 2.  I
think Bjorn usually applies from patchwork so this'll likely be a
problem...


I guess it is updated, now it is showing all the 4 patches

Same comments here as for patch #2.


Ok.

I believe things in this section are supposed to be sorted
alphabetically.  Thus "qup..." should be sorted before "trackpad..."

Ok.
