[RESEND PATCH] ARM: tegra: fix erroneous address in dts

[RESEND PATCH] ARM: tegra: fix erroneous address in dts

[Ralf Ramsauer]

c90bb7b enabled the high speed UARTs of the Jetson TK1. Due to a merge
quirk, wrong addresses were introduced. Fix it and use the correct
addresses.

Thierry let me know, that there is another patch (b5896f67ab3c in
linux-next) in preparation which removes all the '0,' prefixes of unit
addresses on Tegra124 and is planned to go upstream in 4.8, so
this patch will get reverted then.

But for the moment, this patch is necessary to fix current misbehaviour.

ARM-SoC maintainers,

Just to clarify, this is targetted at v4.7 because the offending patch
was merged in v4.7-rc1. If at all possible it'd be great to get this in,
even if this is terribly last minute.

Thanks,
Thierry

I've applied it to the fixes branch, but as Linus is currently offline
and hasn't pulled the previous set of fixes, I suspect it's not
going to make it.

Olof, do you think we should send an amended pull request, or are
we at the point where nothing gets pulled anyway?

thank you very much. If it's not merged in 4.7 then I'll follow up with
a revert patch with stable in Cc.

Yep, didn't make it. I'll resend the fix with stable in Cc tomorrow.
Keep you also in Cc.

Thierry, this fix is only required for 4.7.x and gets superfluous when
b5896f67ab3c is applied. So I guess there is no need to fix mainline, right?

I just notice this was still missing in v4.8-rc1, so I added it to
the fixes branch now, with a stable tag for v4.7

Hi Arnd,

Ahm - this patch should have only be applied if it would have been
possible to commit it before the release of v4.7.

Mainline Patch b5896f6 ("ARM: tegra: Remove commas from unit addresses
on Tegra124") which was introduced during the merge window of v4.8 makes
this patch superfluous and introduces the same error again that we
initially wanted to fix :-)

This patch is only required for stable v4.7.x.

I think the best is to revert it on mainline, as long as stabilization
window is still open.

Hi,

may I poke you again?

Could you please revert this one (b5c86b7 upstream)? It was only
required for 4.7.x where it got already applied.

Thanks

Hi all,

may I *poke* you again?

We're close to the release of 4.8, and this patch (b5c86b749 upstream)
should still be reverted on mainline....
