Subject: Re: [PATCH v9 5/9] arm: omap1: Migrate debug_ll macros to use 8250.S

* Daniel Thompson <daniel.thompson@...aro.org> [140819 08:19]:
> The omap1's debug-macro.S is similar to the generic 8250 code. Compared to

This should be safe to queue together with your other debug_ll
patches, so:

Acked-by: Tony Lindgren <tony@...mide.com>

If you want me to queue this one instead, please let me know.

Regards,

Tony
