* toshiba_acpi: Move sysfs function and struct declarations further downAzael Avalos2015-02-12
| | | | | | | | | | | | | | Commit 93f8c16d635e ("toshiba_acpi: Support new keyboard backlight type") moved all the sysfs structs and function declarations further up in order to make use of sysfs_update_group, however, commit 805469053ba9 ("toshiba_acpi: Add keyboard backlight mode change event") made use of that function unnecesary. This patch moves all the sysfs structs and function declarations further down, making the file shorther in lines and more readable.

* toshiba_acpi: Add support to enable/disable USB 3Azael Avalos2015-02-11
| | | | | | | | | | | | | | Toshiba laptops that come with USB 3 ports have a feature that lets them disable USB 3 functionality and act as a regular USB 2 port, and thus, saving power. This patch adds support to that feature, by creating a sysfs entry named "usb_three", acceptig only two parameters, 0 to disable the USB 3 (acting as a USB 2) and 1 to enable it, however, a reboot is needed everytime this is toggled.

* toshiba_acpi: Add support for Keyboard functions modeAzael Avalos2015-02-11
| | | | | | | | | | | | | | | | | | | | | | 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}. In the "Special Functions" mode, the F{1-12} keys trigger the hotkey and the F{1-12} keys are accessed via FN-F{1-12}.

* toshiba_acpi: Make toshiba_eco_mode_available more robustAzael Avalos2015-02-09
| | | | | | | | | | | | | | | | | | | | | | 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.

* toshiba_acpi: Add a check for TOS_NOT_SUPPORTED in the sci_open functionAzael Avalos2015-01-29
| | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | Newer Toshiba laptops equipped with USB 3.0 ports now have the functionality of rapid charging devices connected to their USB hubs. This patch adds support to use such feature by creating a sysfs entry named "usb_rapid_charge", accepting only two values, 0 to disable and 1 to enable, however, the machine needs a restart everytime the function is toggled.

* toshiba_acpi: Add support for USB Sleep functions under batteryAzael Avalos2015-01-23
| | | | | | | | | | | | | | | | | Toshiba laptops supporting USB Sleep and Charge also come with a feature called "USB functions under battery", which what it does when enabled, is allows the USB Sleep functions when the computer is under battery power. This patch adds support to that function, creating a sysfs entry named "sleep_functions_on_battery", accepting values from 0-100, where zero disables the function and 1-100 sets the battery level at which point the USB Sleep functions will be disabled, and printing the current state of the functon and also the battery level currently set.

* toshiba_acpi: Add support for USB Sleep and Charge functionAzael Avalos2015-01-23
| | | | | | | | | | | | | | | | | | | | Newer Toshiba models now come with a feature called Sleep and Charge, where the computer USB ports remain powered when the computer is asleep or turned off. 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.

* toshiba_acpi: Add keyboard backlight mode change eventAzael Avalos2014-12-03
| | | | | | | | | | | | 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.

* toshiba_acpi: Change notify funtion to handle more eventsAzael Avalos2014-12-03
| | | | | | | | | | | | 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.

| | | | | | | | | | | | | | toshiba-acpi was always missing TOS6207 ID so it did not load automatically on some laptops (such as Portege R100). But it worked fine if loaded manually. Commit 135740de7764 ("toshiba_acpi: Convert to use acpi_driver") broke that and the driver does not work even when loaded manually since then. Add TOS6207 ID to fix it.

* toshiba_acpi: Change HCI/SCI functions return code typeAzael Avalos2014-09-30
| | | | | | | | | | | | | | | Currently the HCI/SCI read/write functions are returning the status of the ACPI call and also assigning the returned value of the HCI/SCI function, however, only the HCI/SCI status is being checked. This patch changes such functions, returning the value of the HCI/SCI function instead of the ACPI call status, eliminating one parameter, and returning something useful that indeed is being checked.

* toshiba_acpi: Unify return codes prefix from HCI/SCI to TOSAzael Avalos2014-09-30
| | | | | | | | | | | | | | The return codes are split in between HCI/SCI prefixes, but they are shared (used) by both interfaces, mixing hci_read/write calls with SCI_* return codes, and sci_read/write calls with HCI_* ones.

* toshiba_acpi: Rename hci_raw to tci_rawAzael Avalos2014-09-30
| | | | | | | | | | | | | | | | | | | | The function name hci_raw was used before to reflect a raw (read/write) call to Toshiba's Hardware Configuration Interface (HCI), however, since the introduction of the System Configuration Interface (SCI), that "name" no longer applies. This patch changes the name of that function to tci_raw (for Toshiba Configuration Interface), and change the comments about it. Also, the HCI_WORDS definition was changed to TCI_RAW, to better reflect that we're no longer using pure HCI calls, but a combination of HCI and SCI, which form part of the Toshiba Configuration Interface.

* toshiba_acpi: Support new keyboard backlight typeAzael Avalos2014-09-17
| | | | | | | | | | | | | | | | | | Newer Toshiba models now come with a new (and different) keyboard backlight implementation with three modes of operation: TIMER, ON and OFF, and the LED is now controlled internally by the firmware. This patch adds support for that type of backlight, changing the existing code to accomodate the new implementation. The timeout value range is now 1-60 seconds, and the accepted modes are now: 1 (FN-Z), 2 (AUTO or TIMER), 8 (ON) and 10 (OFF), this adds two new entries kbd_type and available_kbd_modes, the first shows the keyboard type and the latter shows the supported modes depending on the keyboard type.

* toshiba_acpi: fix and cleanup toshiba_kbd_bl_mode_store()Dan Carpenter2014-09-03
| | | | | | | | | | | | | | | | | | The current code just returns -EINVAL because mode can't be equal to both 1 and 2. Also this function is messy so I have cleaned it up: 1) Remove initializers like "int time = -1". Initializing variables to garbage values turns off GCC's uninitialized variable warnings so it can lead to bugs. 2) Use kstrtoint() instead of sscanf(). 3) Use SCI_KBD_MODE_FNZ and SCI_KBD_MODE_AUTO instead of magic numbers 1 and 2. 4) Don't check for "mode == -1" because that can't happen. 5) Preserve the error code from toshiba_kbd_illum_status_set().
