[PATCH 0/5] Assorted patches for pxa-gpio

[Daniel Mack]

Hi Eric,
Hi Haojian,

here are some patches for gpio-pxa and its bindings. They fix some
flaws I came across while trying to boot a PXA3xx board with v3.10+.


Best regards,
Daniel

[PATCH 1/5] gpio: pxa: remove dead code

[Daniel Mack]

Commit f87311743 ("ARM: mmp: add more compatible names in gpio driver")
changed the driver logic to determine the number of available GPIOs from
the compatible string, and hence obsoleted the (undocumented) child
nodes that were previously necessary. However, it left some remainder
which can be safely removed now.

Also, this patch makes pxa_gpio_probe_dt() return the correct value in
case irq_alloc_descs() fails.

And what about the others? I think the first 3 patches of this series
can go through Linus W, and the other 2 should end up in the pxa tree,
right?

Yes. They might need to build on top of the pinctrl tree.

Or, if there are no other things happening in the PXA tree for the
next merge window, I can take it into my tree, with the ACKs of
e.g. Eric and Olof Johansson.

No, wait. I have some more patches coming soon, and they will cause conflicts then in the merge window. So please take the last two ones into the pxa repo, and only the gpio specific one through Linus W.


Thanks,
Daniel

[PATCH 2/5] gpio: pxa: fix Documentation of interrupt-names property

The property name to pass names for interrupt resources is called
"interrupt-names", not "interrupt-name". Fix it to avoid further

Ok, great, thanks Haojian.

Linus W, 4/5 and 5/5 will be picked and merged by Haojian's tree. That
makes more sense as I have more pxa patches coming.
