[PATCH 0/5] pcmcia: at91_cf: clean up and add DT support

[Joachim Eastwood]

Hi

This series clean up at91_cf a bit and add DT bindings.

Patch series tested on custom RM9200 board in both with DT and
with old platform data.


Joachim Eastwood (5):
  pcmcia: at91_cf: fix gpio_get_value in at91_cf_get_status
  pcmcia: at91_cf: convert to dev_ print functions
  pcmcia: at91_cf: use devm_ functions for allocations
  pcmcia: at91_cf: clean up header includes
  pcmcia: at91_cf: add support for DT

[PATCH 1/5] pcmcia: at91_cf: fix gpio_get_value in at91_cf_get_status

[Joachim Eastwood]

Commit 80af9e6d (pcmcia at91_cf: fix raw gpio number usage) forgot
to change the parameter in gpio_get_value after adding gpio
validation.

[PATCH 2/5] pcmcia: at91_cf: convert to dev_ print functions

[Joachim Eastwood]

Convert all pr_* functions to equivalent dev_* functions and
drop the driver_name variable.

Joachim,

Thanks a lot for these patches. You can add on the whole series:

Acked-by: Nicolas Ferre <nicolas.ferre-AIFe0yeh4nAAvxtiuMwx3w@public.gmane.org>

I hope that it can be taken by linux-pcmcia.

Best regards,

PS: make sure to add linux-arm-kernel mailing-list as well: it always
interests people there to have updates on AT91 peripherals...
