Not a fix.

Not a fix, and should get reviewed and merged via linux-serial mailing
list.

>       OMAP2+: UART: replace omap34xx/omap4xx cpu checks with not omap24xx

Not a fix.

>       OMAP2+: UART: Fix incorrect population of default uart pads

I'll apply this directly with updated comments into fixes.

>       OMAP2+: UART: Add mechanism to probe uart pins and configure rx wakeup

Not ready and too intrusive for -rc cycle.

It seems this can wait as the wake-up events are anyways broken right
now when we remove the muxing.

So not pulling.

OK, will apply to fixes then with Cc stable.
