2015-09-11toshiba_acpi: Fix hotkeys registration on some toshiba modelsAzael Avalos1-5/+3
Commit a2b3471b5b13 ("toshiba_acpi: Use the Hotkey Event Type function for keymap choosing") changed the *setup_keyboard function to query for the Hotkey Event Type to help choose the correct keymap, but turns out that here are certain Toshiba models out there not implementing this feature, and thus, failing to continue the input device registration and leaving such laptops without hotkey support. This patch changes such check, and instead of returning an error if the Hotkey Event Type is not present, we simply inform userspace about it, changing the message printed from err to notice, making the function responsible for registering the input device to continue. This issue was found on a Toshiba Portege Z30-B, but there might be some other models out there affected by this regression as well.

2015-09-11toshiba_acpi: Fix USB Sleep and Music always disabledAzael Avalos1-1/+1
Commit e1a949c1b988 ("toshiba_acpi: Refactor *{get, set} functions return value") made changes on the return type of the HCI/SCI functions, but a typo on the USB Sleep and Music code is always reporting non existent support for such feature. This patch corrects the typo, changing an assignment to a comparison, making the laptops with actual support for such feature to work again.

2015-08-05toshiba_acpi: Remove unnecessary checks and returns in HCI/SCI functionsAzael Avalos1-125/+44
A previous patch added explicit feature checks for support, *SUCCESS* and *FAILURE to the HCI/SCI *{get, set} functions. This patch removes some unnedded checks to the driver HCI/SCI functions given that the default error return value is now set to -EIO, there is no need to check for other error values other than the ones currently checking for.

2015-08-05toshiba_acpi: Refactor *{get, set} functions return valueAzael Avalos1-73/+104
This patch refactors the return value of the driver *{get, set} functions, since the driver default error value is -EIO. All the functions now check for TOS_FAILURE, TOS_NOT_SUPPORTED and TOS_SUCCESS. On TOS_FAILURE a pr_err message is printed informing the user of the error (no change was made to this, except the check was added to the functions not checking for this). On TOS_NOT_SUPPORTED we now return -ENODEV immediately (some functions were returning -EIO and some other were not checking) On TOS_SUCCESS* we now return 0 (as a side effect, a new success value was added, since some functions return one instead of zero to indicate success). As a special case, the LED functions now check for *FAILURE on *set, and check for TOS_FAILURE and TOS_SUCCESS on *get with their "default" return value set to LED_OFF. Also the {lcd, video}_proc* functions were adapted to reflect these changes to their parent HCI functions.

2015-08-05toshiba_acpi: Remove "*not supported" feature printsAzael Avalos1-26/+46
Currently the driver prints "*not supported" if any of the features queried are in fact not supported, let us print the available features instead. This patch removes all instances pr_info printing "*not supported", and add a new function called "print_supported_features", which will print the available laptop features.

2015-08-05toshiba_acpi: Change *available functions return typeAzael Avalos1-67/+62
This patch changes the *available functions return type from int to void. The checks for support of their respective features are done inside such functions and there was no need to return anything as we can flag the queried feature as supported inside these functions. The code was adapted accordingly to these changes and two new variables were created and another was changed from uint to bool. Also, the function toshiba_acceleremoter_supported was renamed to toshiba_accelerometer_available to maintain the naming consistency on the driver.

2015-07-29toshiba_acpi: Add set_fan_status functionAzael Avalos1-26/+40
This patch adds a new function named "set_fan_status" to complement its get* counterpart, as well as to avoid code duplication between "fan_proc_write" and "fan_store". Also, both functions (get*, set*) are now checking for TOS_FAILURE, TOS_NOT_SUPPORTED and TOS_SUCCESS (to be on par with the rest of the HCI/SCI functions), printing an error message, returning -ENODEV and zero respectively. The proc and sysfs functions were updated to reflect these changes as well, returning -EIO for proc, and propagating the error value on the sysfs functions.

Commit f11f999e9890 ("toshiba_acpi: Refuse to load on machines with buggy INFO implementations") denied loading on laptops with a WMI Event GUID given that such laptops manage the hotkeys via that interface, however, such laptops have a working Toshiba Configuration Interface (TCI), and thus, such commit denied several supported features. This patch avoids registering the input device and ignores all hotkey events on laptops with such WMI Event GUID, making the supported features found in those laptops to work.

2015-07-25toshiba_acpi: Add /dev/toshiba_acpi deviceAzael Avalos1-0/+91
There were previous attempts to "merge" the toshiba SMM module to the toshiba_acpi one, they were trying to imitate what the old toshiba module does, however, some models (TOS1900 devices) come with a "crippled" implementation and do not provide all the "features" a "genuine" Toshiba BIOS does. This patch adds a new device called toshiba_acpi, which aim is to enable userspace to access the SMM on Toshiba laptops via ACPI calls. Creating a new convenience _IOWR command to access the SCI functions by opening/closing the SCI internally to avoid buggy BIOS, while at the same time providing backwards compatibility. Older programs (and new) who wish to access the SMM on newer models can do it by pointing their path to /dev/toshiba_acpi (instead of /dev/toshiba) as the toshiba.h header was modified to reflect these changes as well as adds all the toshiba_acpi paths and command, however, it is strongly recommended to use the new IOCTL for any SCI command to avoid any buggy BIOS.

Since the introduction of TOS1900 devices support to the driver, the "keys" entry under the proc directory was broken, given that it only handled TOS620X devices accordingly. This patch adapts the code to show the hotkey values of TOS1900 devices too, and in case some programs are still using that interface, hotkeys reporting should now work on these devices.

2015-04-24toshiba_acpi: Do not register vendor backlight when acpi_video bl is availableHans de Goede1-0/+24
commit a39f46df33c6 ("toshiba_acpi: Fix regression caused by backlight extra check code") causes the backlight to no longer work on the Toshiba Z30, reverting that commit fixes this but restores the original issue fixed by that commit. Looking at the toshiba_acpi backlight code for a fix for this I noticed that the toshiba code is the only code under platform/x86 which unconditionally registers a vendor acpi backlight interface, without checking for acpi_video backlight support first. This commit adds the necessary checks bringing toshiba_acpi in line with the other drivers, and fixing the Z30 regression without needing to revert the commit causing it. Chances are that there will be some Toshiba models which have a non working acpi-video implementation while the toshiba vendor backlight interface does work, this commit adds an empty dmi_id table where such systems can be added, this is identical to how other drivers handle such systems.

Recent Toshiba laptops that come with the new keyboard layout have the Special Functions (hotkeys) enabled by default, which, in order to access the F{1-12} keys, you need to press the FN-F{1-12} key to access such key. This patch adds support to toggle the Keyboard Functions operation mode by creating the sysfs entry "kbd_functions_keys", accepting only two parameters, 0 to set the "Normal Operation" mode and 1 to set the "Special Functions" mode, however, everytime the mode is toggled, a restart is needed. In the "Normal Operation" mode, the F{1-12} keys are as usual and the hotkeys are accessed via FN-F{1-12}.

Some Toshiba laptops do not come with the ECO led installed, however, the driver is registering support for it when it should not. This patch makes the toshiba_eco_mode_available function more robust in detecting ECO led capabilities, not registering the led on laptops that do not support it and registering the led when it really does. The ECO led function now returns 0x8e00 (Not Installed) by querying with in[3] = 0, whenever theres no physical LED installed, and returning 0x8300 (Input Data Error) when it is, however, there are some BIOSes that have stub function calls not returning anything and and the LED device was being registered too, hence the change of the default return value from 1 to 0.

This was "toshiba_acpi: Change sci_open function return value" Some Toshiba laptops have "poorly implemented" SCI calls on their BIOSes and are not checking for sci_{open, close} calls, therefore, the sci_open function is failing and making some of the supported features unavailable (kbd backlight, touchpad, illumination, etc.). This patch checks whether we receive TOS_NOT_SUPPORTED and returns 1, making the supported features work on such laptops. In the case that some laptops really do not support the SCI, all the SCI dependent functions check for TOS_NOT_SUPPORTED, and thus, not registering support for the queried feature.

This patch adds support to such feature, creating a sysfs entry called "usb_sleep_charge" to set the desired charging mode or to disable it. The sysfs entry accepts three parameters, 0, 1 and 2, beign disabled, alternate and auto respectively. The auto mode stands for USB conformant devices (which most are), and the alternate mode stands for those non USB conformant devices that require more power.

2014-12-03toshiba_acpi: Add keyboard backlight mode change eventAzael Avalos1-6/+8
A previous patch added support to handle more events. This patch adds support to update the sysfs group whenever we receive a 0x92 event, which indicates a change in the keyboard backlight mode, removing the update group code from toshiba_kbd_bl_mode_store, as it is no longer needed there.

2014-12-03toshiba_acpi: Change notify funtion to handle more eventsAzael Avalos1-34/+51
Currently the function toshiba_acpi_notify only takes care of hotkeys, however, the TOSXXXX devices receive more events that can be useful. This patch changes the function to be able to handle more events, and in the process, move all hotkey related code residing in it to a new function called toshiba_acpi_process_hotkeys.
