Hi Chris, Ian
AFAICS there are currently still a few tmio patch-series outstanding:
From: Guennadi Liakhovetski <g.liakhovetski <at> gmx.de>
Subject: [PATCH 0/2] tmio_mmc: improve DMA reliability
http://thread.gmane.org/gmane.linux.kernel.mmc/6485
From: Simon Horman <horms <at> verge.net.au>
Subject: [PATCH 0/4] [rfc v3] mmc, ARM: Add zboot from eSD support for SuperH Mobile ARM
http://thread.gmane.org/gmane.linux.kernel.mmc/6664
From: Guennadi Liakhovetski <g.liakhovetski <at> gmx.de>
Subject: [PATCH 0/6] mmc: split the tmio driver into several modules
http://thread.gmane.org/gmane.linux.ports.sh.devel/10304
From: Guennadi Liakhovetski <g.liakhovetski <at> gmx.de>
Subject: [PATCH 0/4 v2] mmc: tmio: don't access nonexisting registers
http://thread.gmane.org/gmane.linux.ports.sh.devel/10311
From: Guennadi Liakhovetski <g.liakhovetski <at> gmx.de>
Subject: [PATCH/RFC 0/2 v2] mmc: tmio: power management and clock gating
http://thread.gmane.org/gmane.linux.kernel.mmc/6627
Of those the first patchset shouldn't have any issues.
I haven't followed discussions regarding the second patchset from Simon -
is it going to be applied as is, or is a new revision required?
If it is going to be applied, shall I rebase my remaining patches on top
of it or would you prefer Simon to rebase his patches (I think, he has
only one patch, touching tmio: [PATCH 1/4])? As for the rest of the
patches, IIRC, the only remaining issue, that I'll be fixing today is
Magnus' wish to allocate the bounce buffer dynamically. Although, I could
imagine doing that incrementally, because the #ifdef, that Magnus would
like to get rid of is already now in the code, it is not introduced by
these my patches. But I can redo my patches too, no problem.
What would be the preferred approach?
Thanks
Guennadi
