[PATCH v3 4/7] pinctrl: Add driver for Zynq

From: Soren Brinkmann
Date: Fri Dec 12 2014 - 11:37:00 EST


This adds a pin-control driver for Zynq.

Signed-off-by: Soren Brinkmann <soren.brinkmann@xxxxxxxxxx>
Tested-by: Andreas FÃrber <afaerber@xxxxxxx>
---
Changes since v2:
- driver-specific DT properties are passed to the core in two arrays,
one for the actual DT parsing one for the debugfs representation.
Issue a compiler warning when the number of entries is not the same
for both arrays.

Changes since v1:
- fix EMIO_SD1_CD pin name
- add USB to pinmux options

changes since RFCv2:
- let Zynq select PINCTRL_ZYNQ. Boot hangs when pinctrl information is
present in DT but no driver available.
- add #defines to get rid of magical constants
- add commas at end of initializers
- separate changes in mach-zynq in separate patch
- add driver specific io-standard DT property
- refactored pinconf set function to not require arguments for
argument-less properties
- squash other patches in
- support for IO-standard property
- support for low-power mode property
- migration to pinconf_generic_dt_node_to_map_all()
- use newly created infrastructure to add pass driver-specific DT
params to pinconf-generic

changes since RFC:
- use syscon/regmap to access registers in SLCR space
- rebase to 3.18: rename enable -> set_mux
- add kernel-doc
- support pinconf
- supported attributes
- pin-bias: pull up, tristate, disable
- slew-rate: 0 == slow, 1 == fast; generic pinconf does not display
argument
