I've verified combination of
[PATCH] drivers: pinctrl: add active state to core
[RFC] ARM: OMAP2+: omap_device: add pinctrl handling
on OMAP4 SDP board+UARTs and going to send patches on Monday.

So, Acked/Tested-by: Grygorii Strashko <grygorii.strashko@...com>
(I can't reply directly to thread - not signed to those lists :))

What is the best branch to base my patches on?
