| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This allows to write drm-$(CONFIG_AGP) += drm_agpsupport.o without having to handle CONFIG_AGP=y vs. CONFIG_AGP=m. Only support this syntax for modules, since built-in code depending on something modular cannot work and init/Makefile actually relies on the current semantics. There are a few drivers which adapted to the current semantics out of necessity; these are fixed to also work when the respective subsystem is modular.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | The ad7606_par and ad7606_spi drivers are not built if CONFIG_AD7606=m, because kbuild does not currently support <objname>-m syntax. Even if we add kbuild support, ad7606 fails to link, because of duplicate module_init definitions. Make the two drivers separate modules, as the Kconfig help text already suggests. Also, CONFIG_IIO_BUFFER is a dependency of CONFIG_AD7606, so there is no need to test for it in the Makefile. Signed-off-by: Michal Marek <mmarek@suse.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | BIOS/ACPI on devices with WMI interface version 0 does not clear buffer before filling it. So next time when BIOS/ACPI send WMI event which is smaller as previous then it contains garbage in buffer from previous event. BIOS/ACPI on devices with WMI interface version 1 clears buffer and sometimes send more events in buffer at one call. Since commit 83fc44c32ad8 ("dell-wmi: Update code for processing WMI events") dell-wmi process all events in buffer (and not just first). To prevent reading garbage from the buffer we process only the first event on devices with WMI interface version 0.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Certain Toshiba models with the second generation keyboard backlight (type 2) do not generate the keyboard backlight changed event (0x92), and thus, the sysfs entries are never being updated. This patch adds a workquee and a global boolean variable to address the issue. For those models that do generate the event, the sysfs entries are being updated via the *notify function and the boolean is set to true to avoid a second call to update the entries. For those models that do not generate the event, the workquee is used to update the sysfs entries and also to emulate the event via netlink, to make userspace aware of such change.

| * | toshiba_acpi: Add WWAN RFKill supportAzael Avalos2015-11-231-3/+76
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A previuos patch added WWAN support to the driver, allowing to query and set the device status. This patch adds RFKill support for the recently introduced WWAN device, making use of the WWAN and *wireless_status functions to query the killswitch and (de)activate the device accordingly to its status.

| * | toshiba_acpi: Add support for WWAN devicesAzael Avalos2015-11-231-0/+109
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Toshiba laptops with WWAN devices installed cannot use the device unless it is attached and powered, similar to how Toshiba Bluetooth devices work. This patch adds support to WWAN devices, introducing three functions, one to query the overall status of the wireless devices (RFKill, WLAN, BT, WWAN), the second queries WWAN support, and finally the third (de)activates the device.

| * | toshiba_acpi: Fix blank screen at boot if transflective backlight is supportedAzael Avalos2015-11-211-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If transflective backlight is supported and the brightness is zero (lowest brightness level), the set_lcd_brightness function will activate the transflective backlight, making the LCD appear to be turned off. This patch fixes the issue by incrementing the brightness level, and by doing so, avoiding the activation of the tranflective backlight.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The driver uses genetlink to inform userspace of events generated by the system, but the data passed is always zero as there is no data to pass, except for the hotkey event. This patch propagates the hotkey value via genetlink so userspace can make use of it. Signed-off-by: Azael Avalos <coproscefalo@gmail.com> Signed-off-by: Darren Hart <dvhart@linux.intel.com>
