[x86] update alix2 platform driver
Add support for Ed Wildgoose's alix platform driver plus my enhancement to add GPIO soft button support. Signed-off-by: Philip Prindeville <philipp@redfish-solutions.com> git-svn-id: svn://svn.openwrt.org/openwrt/trunk@28081 3c298f89-4303-0410-b956-a3cf2f4a3e73

|
||||||
|
|
||||||
|
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 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.
