pinctrl: generic: Make 'conf_items' static

2013-03-27T21:48:08+00:00

'conf_items' is used only in this file. Silences the below
sparse warning:
drivers/pinctrl/pinconf-generic.c:37:24: warning:
symbol 'conf_items' was not declared. Should it be static?

pinctrl: generic: rename input schmitt disable

2013-02-15T08:52:29+00:00

Rename PIN_CONFIG_INPUT_SCHMITT_DISABLE to
PIN_CONFIG_INPUT_SCHMITT_ENABLE. It's used to make it more generialize.

pinctrl: add pinconf-generic defines for output

2013-01-11T20:49:20+00:00

This adds a definition of a generic output configuration
for a certain pin when using the generic pin configuration
library. Whereas driving pins low/high is usually a GPIO
business, you may want to set up pins into a default state
using hogs, and never touch them again. This helps out
with that scenario.

Based on a patch from Patrice Chotard.

pinctrl: generic: add input schmitt disable parameter

2012-11-21T07:55:26+00:00

In Marvell PXA/MMP silicons, input schmitt disable value is 0x40, not 0.
So append new config parameter -- input schmitt disable.

pinctrl: introduce generic pin config

2012-03-12T21:49:02+00:00

This is a split-off from the earlier patch set which adds generic
pin configuration for the pin controllers that want it. Since
we may have a system with mixed generic and custom pin controllers,
we pass a boolean in the pin controller ops vtable to indicate
if it is generic.

ChangeLog v1->v5:
- Follow parent patch versioning number system.
- Document the semantic meaning of return values from pin config
  get functions, so we can iterate over pins and check their
  properties from debugfs as part of the generic config code.
- Use proper cast functions in the generic debugfs pin config
  file.
- Expand generic config to optionally cover groups too.
ChangeLog v5->v6:
- Update to match underlying changes.
ChangeLog v6->v7:
- Drop DRIVE_OFF parameter, use bias high impedance for this
- Delete argument for drive modes push-pull, od and os. These
  are now just state transitions.
- Delete slew rate rising/falling due to discussions on on
  proper semantics
- Drop config wakeup, struct irq_chip does this for now, add
  back if need be.
- Set PIN_CONFIG_END to 0x7fff making room for custom config
  parameters from 0x8000 and up.
- Prefix accessor functions with pinconf_
