[PATCH v3 0/7] pcmcia: at91_cf: clean up and add DT support

[Nicolas Ferre]

These patches clean up at91_cf a bit and add DT bindings.
They are based on a previous series from Joachim Eastwood and other cleanup
patches by Fabio and Laurent.
I have collected them together as they are lying around for some time.

Greg kindly told me that he can take them through his char/misc driver
tree, so I resend the series.

Thanks for your help, best regards.

v3: rebased on top of 3.10-rc4

v2: add 2 more cleanup patches:
	- move to module_platform_driver_probe()
	- little trivial indentation fix

Fabio Porcedda (1):
  pcmcia: at91_cf: use module_platform_driver_probe()

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

Laurent Navet (1):
  pcmcia/trivial: at91_cf: fix checkpatch error

[PATCH v3 1/7] pcmcia: at91_cf: fix gpio_get_value in at91_cf_get_status

[Nicolas Ferre]

From: Joachim Eastwood <manabian@gmail.com>

Commit 80af9e6d (pcmcia at91_cf: fix raw gpio number usage) forgot

[PATCH v3 2/7] pcmcia: at91_cf: convert to dev_ print functions

[Nicolas Ferre]

From: Joachim Eastwood <manabian@gmail.com>

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