x86/platform: Make platform/geode/net5501.c explicitly non-modular

2016-02-16T08:11:09+00:00

The Kconfig currently controlling compilation of this code is:

  arch/x86/Kconfig:config NET5501
  arch/x86/Kconfig:       bool "Soekris Engineering net5501 System Support (LEDS, GPIO, etc)"

...meaning that it currently is not being built as a module by anyone.

Lets remove the couple traces of modularity, so that when reading
the driver there is no doubt it is builtin-only.

Since module_init translates to device_initcall in the non-modular
case, the init ordering remains unchanged with this commit.

We also delete the MODULE_LICENSE tag etc. since all that information
is already contained at the top of the file in the comments.

x86/platform: Make platform/geode/alix.c explicitly non-modular

2016-02-16T08:11:09+00:00

The Kconfig currently controlling compilation of this code is:

  arch/x86/Kconfig:config ALIX
  arch/x86/Kconfig:       bool "PCEngines ALIX System Support (LED setup)"

...meaning that it currently is not being built as a module by anyone.

Lets remove the modular code that is essentially orphaned, so that
when reading the driver there is no doubt it is builtin-only.

Since module_init translates to device_initcall in the non-modular
case, the init ordering remains unchanged with this commit.

We replace module.h with moduleparam.h since the file does declare
some module parameters, and leaving them as such is currently the
easiest way to remain compatible with existing boot arg use cases.

We also delete the MODULE_LICENSE tag etc. since all that information
is already contained at the top of the file in the comments.

x86/geode: Fix incorrect placement of __initdata tag

2013-10-01T11:21:27+00:00

__initdata tag should be placed between the variable name and
equal sign for the variable to be placed in the intended
.init.data section.

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.
