 Actually, reg/interrupts are from the OF core.  There's no need to
 mention them here.
 Tomasz complained when I left those parts out so I added them in v2.
 Since it's there now, I don't mind either way. Let's just agree on one
 way or the other.
 

Binding was Acked-by Rob and that's why I believe this should be fine.

Thanks,

What's the naming convention we should follow?

Is sdhci-of-arasan.c OK? Or should we use sdhci-arasan.c instead?

[PATCH v2 1/2] mmc: arasan: Add driver for Arasan SDHCI

2013-10-30 Thread Soren Brinkmann
Add a driver for Arasan's SDHCI controller core.

Signed-off-by: Soren Brinkmann 
---
v2:
 - document 'interrupts' and 'interrupt-parent' properties in the driver
   bindings
 - append '-8.9a' IP version specifier to comaptibility string
