leds: add led driver for Bachmann's ot200

2012-01-23T16:38:47+00:00

Add support for leds on Bachmann's ot200 visualisation device.  The
device has three leds on the back panel (led_err, led_init and led_run)
and can handle up to seven leds on the front panel.

The driver was written by Linutronix on behalf of Bachmann electronic
GmbH.  It incorporates feedback from Lars-Peter Clausen

leds: add driver for TCA6507 LED controller

2012-01-11T00:30:49+00:00

TI's TCA6507 is the LED driver in the GTA04 Openmoko motherboard.  The
driver provides full support for brightness levels and hardware blinking.

This driver can drive each of 7 outputs as an LED or a GPIO output,
and provides hardware-assist blinking.

leds: Renesas TPU LED driver

2011-11-01T00:30:54+00:00

Add V2 of the LED driver for a single timer channel for the TPU hardware
block commonly found in Renesas SoCs.

The driver has been written with optimal Power Management in mind, so to
save power the LED is driven as a regular GPIO pin in case of maximum
brightness and power off which allows the TPU hardware to be idle and
which in turn allows the clocks to be stopped and the power domain to be
turned off transparently.

Any other brightness level requires use of the TPU hardware in PWM mode.
TPU hardware device clocks and power are managed through Runtime PM.
System suspend and resume is known to be working - during suspend the LED
is set to off by the generic LED code.

The TPU hardware timer is equipeed with a 16-bit counter together with an
up-to-divide-by-64 prescaler which makes the hardware suitable for
brightness control.  Hardware blink is unsupported.

The LED PWM waveform has been verified with a Fluke 123 Scope meter on a
sh7372 Mackerel board.  Tested with experimental sh7372 A3SP power domain
patches.  Platform device bind/unbind tested ok.

V2 has been tested on the DS2 LED of the sh73a0-based AG5EVM.

x86: geode: New PCEngines Alix system driver

2011-09-21T09:19:42+00:00

This new driver replaces the old PCEngines Alix 2/3 LED driver with a
new driver that controls the LEDs through the leds-gpio driver. The
old driver accessed GPIOs directly, which created a conflict and
prevented also loading the cs5535-gpio driver to read other GPIOs on
the Alix board. With this new driver, we hook into leds-gpio which in
turn uses GPIO to control the LEDs and therefore it's possible to
control both the LEDs and access onboard GPIOs

Driver is moved to platform/geode as requested by Grant and any other
geode initialisation modules should move here also

This driver is inspired by leds-net5501.c by Alessandro Zummo.

Ideally, leds-net5501.c should also be moved to platform/geode. 
Additionally the driver relies on parts of the patch: 7f131cf3ed ("leds:
leds-alix2c - take port address from MSR) by Daniel Mack to perform
detection of the Alix board.

leds: provide helper to register "leds-gpio" devices

2011-05-25T15:39:51+00:00

This function makes a deep copy of the platform data to allow it to live
in init memory.  For a kernel that supports several machines and so
includes the definition for several leds-gpio devices this saves quite
some memory because all but one definition can be free'd after boot.

As the function is used by arch code it must be builtin and so cannot go
into leds-gpio.c.
