2012-03-20samsung-laptop: remove selftestCorentin Chary
We can now do the self test using debugfs, so remove the code and keep the debug flag to enable more traces. Signed-off-by: Corentin Chary <corentincj@iksaif.net> Acked-by: Greg Kroah-Hartman <gregkh@suse.de> Signed-off-by: Matthew Garrett <mjg@redhat.com>
2012-03-20samsung-laptop: add a small debugfs interfaceCorentin Chary
This allow to call arbitrary sabi commands wihout modifying the driver at all. For example, setting the keyboard backlight brightness to 5 using debugfs interface can be done like that: ; Set the command echo 0x78 > command ; Set the data echo 0x0582 > d0 ; Fill the rest with 0 echo 0 > d1 echo 0 > d2 echo 0 > d3 ; And issue the command cat call Signed-off-by: Corentin Chary <corentincj@iksaif.net> Acked-by: Greg Kroah-Hartman <gregkh@suse.de> Signed-off-by: Matthew Garrett <mjg@redhat.com>
2012-03-20samsung-laptop: ehance SABI supportCorentin Chary
* SABI command are on 16 bits, not 8 * SABI can read/write up to 11 byte of data * There is not real difference between "get" and "set" commands, so refactorise the code of both functions Signed-off-by: Corentin Chary <corentincj@iksaif.net> Acked-by: Greg Kroah-Hartman <gregkh@suse.de> Signed-off-by: Matthew Garrett <mjg@redhat.com>

2012-03-20samsung-laptop: don't handle backlight if handled by acpi/videoCorentin Chary
samsung-laptop is not at all related to ACPI, but since this interface is not documented at all, and the driver has to use it at load to understand how it works on the laptop, I think it's a good idea to disable it if a better solution is available.

2012-03-20samsung-laptop: move code into init/exit functionsCorentin Chary
Create _init()/_exit() function for each subsystem, remove the local struct samsung_laptop * and only keep a struct platform_device * that can only be used in samsung_init() and samsung_exit().

2012-03-20samsung-laptop: put all local variables in a single structureCorentin Chary
Even if this driver can only be loaded once, it is still a good idea to create some kind of context structure. Signed-off-by: Corentin Chary <corentincj@iksaif.net> Acked-by: Greg Kroah-Hartman <gregkh@suse.de> Signed-off-by: Matthew Garrett <mjg@redhat.com>

2012-03-20to fix scancodes returned by sony-laptop driverJohn Hughes
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 Boyer
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).
