asus_acpi only support old models, it has been deprecated since 2009 in favor of asus-laptop, it's not built by any (sane) distro, so it is time to say good bye. Thanks to Julien Lerouge and Karol Kozimor for the work they have done on it, I would never have wrote asus-laptop and other asus related drivers without asus_acpi.

2012-03-20asus-laptop: control how BLED and WLED should be exposedCorentin Chary1-33/+116
Let the user tells if BLED and WLED should be exposed as led or rfkill (the old sysfs are still here, but this adds a standard interface to control the device). For example on my A6JC, with WAPF=1, I would do: $ modprobe asus-laptop wled_type=led bluetooth_type=rfkill There is still no known way to automatically guess what BLED and WLED methods will control, it's why user information is needed. A userspace database could do that automatically, and maybe some DMI matching in the driver. Signed-off-by: Corentin Chary <corentin.chary@gmail.com> Signed-off-by: Matthew Garrett <mjg@redhat.com>

This enable the driver for everything that look like a laptop and is from vendor "SAMSUNG ELECTRONICS CO., LTD.". Note that laptop supported by samsung-q10 seem to have a different vendor strict. Also remove every log output until we know that we have a SABI interface (except if the driver is forced to load, or debug is enabled).

2012-03-20to fix scancodes returned by sony-laptop driverJohn Hughes1-5/+8
Fix scancodes returned by driver to match scancodes used to remap keys. (Before the patch FN/E returned scancode 0x1B, but to remap scancode 0x14 had to be used). The scancodes returned by the sony-laptop driver for function keys did not match the scancodes used to remap keys. Also, since the scancode was sent to the input subsystem after the mapped keysym the /lib/udev/keymap utility was confused about which scancode to report for which keysym. This patch fixes the driver so the correct scancode is shown for each key. It also adds to the documentation a description of where to find the scancodes.

2012-03-20sony-laptop: Enable keyboard backlight by defaultJosh Boyer1-1/+1
When the keyboard backlight support was originally added, the commit said to default it to on with a 10 second timeout. That actually wasn't the case, as the default value is commented out for the kbd_backlight parameter. Because it is a static variable, it gets set to 0 by default without some other form of initialization. However, it seems the function to set the value wasn't actually called immediately, so whatever state the keyboard was in initially would remain. Then commit df410d522410e67660 was introduced during the 2.6.39 timeframe to immediately set whatever value was present (as well as attempt to restore/reset the state on module removal or resume). That seems to have now forced the light off immediately when the module is loaded unless the option kbd_backlight=1 is specified. Let's enable it by default again (for the first time).

2012-02-21asm-generic: architecture independent readq/writeq for 32bit environmentHitoshi Mitake2-26/+4
This provides unified readq()/writeq() helper functions for 32-bit drivers. For some cases, readq/writeq without atomicity is harmful, and order of io access has to be specified explicitly. So in this patch, new two header files which contain non-atomic readq/writeq are added. - <asm-generic/io-64-nonatomic-lo-hi.h> provides non-atomic readq/ writeq with the order of lower address -> higher address - <asm-generic/io-64-nonatomic-hi-lo.h> provides non-atomic readq/ writeq with reversed order This allows us to remove some readq()s that were added drivers when the default non-atomic ones were removed in commit dbee8a0affd5 ("x86: remove 32-bit versions of readq()/writeq()") The drivers which need readq/writeq but can do with the non-atomic ones must add the line: #include <asm-generic/io-64-nonatomic-lo-hi.h> /* or hi-lo.h */ But this will be nop in 64-bit environments, and no other #ifdefs are required. So I believe that this patch can solve the problem of 1. driver-specific readq/writeq 2. atomicity and order of io access This patch is tested with building allyesconfig and allmodconfig as ARCH=x86 and ARCH=i386 on top of tip/master.
