leds: add new lp8788 led driver

2012-07-26T04:04:33+00:00

TI LP8788 PMU has the current sink as the keyboard led driver.
The brightness is controlled by the i2c commands.
Configurable parameters can be defined in the platform side.

Patch v2.
(a) use workqueue on changing the brightness

(b) use mutex_lock/unlock when the brightness is set
    and the led block of lp8788 device is enabled

(c) remove err_dev on _probe()
    : just return as returned value if any errors

(d) replace module_init/exit() with module_platform_driver()

(e) add led configuration structure and loading them by default
    if platform data is null

LEDS: add BlinkM RGB LED driver, documentation and update MAINTAINERS

2012-07-24T08:00:51+00:00

Add driver for BlinkM device to drivers/leds/.
Add entry to MAINTAINERS file.
Add documentation in Documentation/leds/.

A BlinkM is a RGB LED controlled through I2C.

This driver implements an interface to the LED framework
and another sysfs group to access the internal options
of the BlinkM.

rev6: Use module_i2c_driver().
rev5: Removed own workqueue in favor of events wq.
rev4: Fixed comments by Bryan Wu.
rev3: Fixed issues found by Jonathan Neuschäfer.

leds: Add LED driver for lm3556 chip

2012-07-23T23:52:35+00:00

LM3556 :
The LM3556 is a 4 MHz fixed-frequency synchronous boost
converter plus 1.5A constant current driver for a high-current white LED.
Datasheet: www.national.com/ds/LM/LM3556.pdf

Tested on OMAP4430

(bryan.wu@canonical.com: use module_i2c_driver() rather than
lm3556_init/lm3556_exit for code simplicity; fixed some typo
pointed out by Rob Landley)

leds: add new transient trigger for one shot timer activation

2012-05-29T23:22:32+00:00

The leds timer trigger does not currently have an interface to activate a
one shot timer.  The current support allows for setting two timers, one
for specifying how long a state to be on, and the second for how long the
state to be off.  The delay_on value specifies the time period an LED
should stay in on state, followed by a delay_off value that specifies how
long the LED should stay in off state.  The on and off cycle repeats until
the trigger gets deactivated.  There is no provision for one time
activation to implement features that require an on or off state to be
held just once and then stay in the original state forever.

Without one shot timer interface, user space can still use timer trigger
to set a timer to hold a state, however when user space application
crashes or goes away without deactivating the timer, the hardware will be
left in that state permanently.

As a specific example of this use-case, let's look at vibrate feature on
phones.  Vibrate function on phones is implemented using PWM pins on SoC
or PMIC.  There is a need to activate one shot timer to control the
vibrate feature, to prevent user space crashes leaving the phone in
vibrate mode permanently causing the battery to drain.

This trigger exports three properties, activate, state, and duration When
transient trigger is activated these properties are set to default values.

- duration allows setting timer value in msecs. The initial value is 0.
- activate allows activating and deactivating the timer specified by
  duration as needed. The initial and default value is 0.  This will allow
  duration to be set after trigger activation.
- state allows user to specify a transient state to be held for the specified
  duration.

Merge tag 'boards' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

2012-03-27T23:27:28+00:00

Pull "ARM: board specific updates" from Arnd Bergmann/Olof Johansson:
 "These changes are all specific to one board only.  We're trying to
  keep the number of board files low, but generally board level updates
  are ok on platforms that are working on moving towards DT based
  probing, which will eventually lead to removing them.

  The board-ams-delta.c board file gets a conflict between the removal
  of ams_delta_config and the addition of a lot of other data.  The
  Kconfig file has two changes in the same line, and in exynos, the
  power domain cleanup conflicts with the addition of the image sensor
  device.
