pinctrl: Pass all configs to driver on pin_config_set()

2013-08-28T11:34:41+00:00

When setting pin configuration in the pinctrl framework, pin_config_set() or
pin_config_group_set() is called in a loop to set one configuration at a time
for the specified pin or group.

This patch 1) removes the loop and 2) changes the API to pass the whole pin
config array to the driver.  It is now up to the driver to loop through the
configs.  This allows the driver to potentially combine configs and reduce the
number of writes to pin config registers.

All c files changed have been build-tested to verify the change compiles and
that the corresponding .o is successfully generated.

pinctrl: tegra: use pinctrl-utils APIs for mapping

2013-08-23T06:56:32+00:00

Pin control utility functions provides the function for creating
map lists.

In place of implementing APIs locally in Tegra pin control driver
for creating map lists, use the utility functions. This reduces
the code size and avoid duplication.

Changes from V1:
- Rebased change on top of V1.
- Use pinctrl_utils_dt_free_map

pinctrl: Declare operation structures as const

pinctrl: tegra: add support for rcv-sel and drive type

2013-01-18T15:13:52+00:00

NVIDIA's Tegra114 added two more configuration parameter in pinmux i.e.
rcv-sel and drive type.

rcv-sel: Select between High and Normal VIL/VIH receivers.
	RCVR_SEL=1: High VIL/VIH
	RCVR_SEL=0: Normal VIL/VIH

drv_type: Ouptput drive type:
	33-50 ohm driver: 0x1
	66-100ohm driver: 0x0

Add support of these parameters to be configure from DTS file.

Tegra20 and Tegra30 does not support this configuration and hence initialize their
pinmux structure with reg = -1.

Originally written by Pritesh Raithatha.
Changes by ldewangan:
	- remove drvtype_width as it is always 2.
	- Better describe the change.

Drivers: pinctrl: remove __dev* attributes.

2013-01-03T23:57:02+00:00

CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, __devinitdata,
and __devexit from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

Merge tag 'driver-core-3.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core

2012-12-11T21:13:55+00:00

Pull driver core updates from Greg Kroah-Hartman:
 "Here's the large driver core updates for 3.8-rc1.

  The biggest thing here is the various __dev* marking removals.  This
  is going to be a pain for the merge with different subsystem trees, I
  know, but all of the patches included here have been ACKed by their
  various subsystem maintainers, as they wanted them to go through here.

  If this is too much of a pain, I can pull all of them out of this tree
  and just send you one with the other fixes/updates and then, after
  3.8-rc1 is out, do the rest of the removals to ensure we catch them
  all, it's up to you.  The merges should all be trivial, and Stephen
  has been doing them all in linux-next for a few weeks now quite
  easily.

  Other than the __dev* marking removals, there's nothing major here,
  some firmware loading updates and other minor things in the driver
  core.

  All of these have (much to Stephen's annoyance), been in linux-next
  for a while.
