2012-03-26asus-wmi: don't update power and brightness when using scalarCorentin Chary1-7/+13
But we can still do it on other boards, as this might happen if the backlight driver change when update_bl is called. Signed-off-by: Corentin Chary <corentin.chary@gmail.com> Signed-off-by: Matthew Garrett <mjg@redhat.com>
2012-03-26asus-wmi: move WAPF variable into quirks_entryCorentin Chary1-2/+2
Some models work better with different values of wapf, so move the variable into quriks_entry to make it more easy to give a specific value to different models.

2012-03-26asus-wmi: store backlight power status for AIO machineAceLan Kao1-13/+20
Due to some implementation reasons, ASUS ET2012 All-in-One machines can't report the correct backlight power status, it will always return 1. To track the backlight power status correctly, we have to store the status by ourselves. BTW, by the BIOS design, the backlight power will be turn on/off sequently, no matter what the value of the parameter will be. More over, the brightness adjustment command will turn on the backlight power. Those behaviors will make us fail to track the backlight power status. For example, While we are trying to turn on the backlight power, we will send out the brightness adjustment command and then trying to figure out if we have to turn on the backlight power, then send out the command. But, the real case is that, the backlight power turns on while sending the brightness adjustment command, and then we send out the command to turn on the backlight power, it actually will turn off the backlight power and the backlight power status we recorded becomes wrong. So, we have to seperate these two commands by a if statement.

2012-03-26asus-wmi: add scalar board brightness adj. supportAceLan Kao1-5/+28
Some ASUS ET2012E/I All-in-One machines that use a scalar board to control the brightness, and they only accept brightness up and down command. So, I introduced a get_scalar_command() function to pass the command to the scalar board through WMI. Besides, we have to store the brightness value locally, for we need the old value to know the brightness value is increasing or decreasing. BTW, since there is no way to retrieve the actual brightness(it would be a fixed value), and the max brightness value would be fixed to 1, so we have to keep passing the brightness up/down command when we reached the max brightness value or 0.

2011-10-24platform-drivers-x86: asus-wmi: fix resource leak in asus_wmi_led_exitAxel Lin1-1/+3
This patch fixes wrong test for successful registered led_classdev, and also fixes a leak due to missing led_classdev_unregister call for asus->kbd_led in asus_wmi_led_exit. device_create returns &struct device pointer on success, or ERR_PTR() on error. Thus if led_classdev_register fails, led_cdev->dev is always not NULL. Thus to unregister a successful registered led_classdev, we should check (!IS_ERR_OR_NULL(asus->tpd_led.dev)) instead of (asus->tpd_led.dev). we use IS_ERR_OR_NULL instead of IS_ERR because if we havn't call led_classdev_register, the led_cdev->dev is NULL.

2011-03-28asus-wmi: try to guess the right DSTS methodsCorentin Chary1-33/+66
This is tricky, new WMI aware notebooks seems to use 0x53545344 while Eee PCs are using 0x53544344. But there is no way to know if there is an Eee PC in that wild that is using 0x53545344 or a notebook using 0x53544344. So the driver try to guess the available DSTS method ... But most Eee PCs never return 0xFFFFFFFE when a method is not available, they return 0 instead (and that's useless). So, first, try 0x53544344 then 0x53545344. We will find a better way when we got more data. Signed-off-by: Corentin Chary <corentincj@iksaif.net> Signed-off-by: Matthew Garrett <mjg@redhat.com>

Also pack struct bios_arg, and make sure that we always send a 64bit buffer when calling a WMI method, because this is needed on Asus notebooks.

2011-03-28eeepc-wmi: asus generic asus-wmi.ko moduleCorentin Chary1-488/+436
New Asus notebooks are using a WMI device similar to the one used in Eee PCs. Since we don't want to load eeepc-wmi module on Asus notebooks, and we want to keep the eeepc-wmi module for backward compatibility, this patch introduce a new module, named asus-wmi, that will be used by eeepc-wmi and the new Asus Notebook WMI Driver. eeepc-wmi's input device strings (device name and phys) are kept, but rfkill and led names are changed (s/eeepc/asus/). This should not break anything since rfkill are used by type or index, not by name, and the eeepc::touchpad led wasn't working correctly before 2.6.39 anyway.
