arch/x86/platform/geode/net5501.c: change active_low to 0 for LED driver

2012-05-04T21:40:07+00:00

It seems that there was an error with the active_low = 1 for the
LED, since it should be set to 0 (meaning that active is high,
since 0 is false, hence the confusion.

The wiki article about it confuses it, since it contradicts itself,
regarding what turns on the LED.

I have tested 3.4-rc2 on my net5501 with this patch, and it makes the LED
behave correctly, where "none" turns it off, and "default-on" turns it on,
when echoed onto the trigger "file" in /sys/class/leds.

Merge branch 'for_linus' of git://cavan.codon.org.uk/platform-drivers-x86

2012-03-28T21:20:23+00:00

Pull x86 platform driver updates from Matthew Garrett:
 "Some significant updates to samsung-laptop, additional hardware
  support for Toshibas, misc updates to various hardware and a new
  backlight driver for some Apple machines."

Fix up trivial conflicts: geode Geos update happening next to net5501
support, and MSIC thermal platform support added twice.

geos: Platform driver for Geos and Geos2 single-board computers.

2012-03-20T16:02:23+00:00

Trivial platform driver for Traverse Technologies Geos and Geos2
single-board computers. Uses SMBIOS to identify platform.
Based on progressive revisions of the leds-net5501 driver that
was rewritten by Ed Wildgoose as a platform driver.

Supports GPIO-based LEDs (3) and 1 polled button which is
typically used for a soft reset.

x86/geode/net5501: Add platform driver for Soekris Engineering net5501

2012-03-06T08:23:56+00:00

Add platform driver for the Soekris Engineering net5501 single-board
computer.  Probes well-known locations in ROM for BIOS signature
to confirm correct platform.  Registers 1 LED and 1 GPIO-based
button (typically used for soft reset).

x86/geode/alix2: Supplement driver to include GPIO button support

2012-03-06T08:23:56+00:00

GPIO 24 is used in reference designs as a soft-reset button, and
the alix2 is no exception.  Add it as a gpio-button.

Use symbolic values to describe BIOS addresses.

Record the model number.

module_param: make bool parameters really bool (arch)

2012-01-12T23:02:18+00:00

module_param(bool) used to counter-intuitively take an int.  In
fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy
trick.

It's time to remove the int/unsigned int option.  For this version
it'll simply give a warning, but it'll break next kernel version.

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.
