d50c9005d3 toshiba_acpi: Reorder toshiba_acpi_alt_keymap entries
This patch simply reorders the entries found in the new keymap by
ascending order, this is simply a cosmetic change, no functionality
was modified.

d7e4f2e2ca toshiba_acpi: Remove unused wireless defines
Commit 2b74103547 ("toshiba_acpi: Remove bluetooth rfkill code")
removed bluetooth related code, however, the wireless defines were
not removed and are unused.

This patch simply removes those defines as there is no code using
them.

695f606090 toshiba_acpi: Transflective backlight updates
This patch changes the tr function second parameter from bool to u32,
to be on par with the rest of the TCI functions of the driver, and the
code was updated accordingly.

Also, the check for translective support was moved to the *add
function, as the {__get, set}_lcd_brightness functions make use of it.

a88bc06e5a toshiba_acpi: Avoid registering input device on WMI event laptops
Commit f11f999e98 ("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.

fc5462f852 toshiba_acpi: Add /dev/toshiba_acpi device
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.

7deef550f3 toshiba_acpi: Adapt /proc/acpi/toshiba/keys to TOS1900 devices
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.

358d6a2c3e toshiba_acpi: Do not register vendor backlight when acpi_video bl is available
commit a39f46df33 ("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.

returning 0x8300 (Input Data Error) when it is, however, there are

and the LED device was being registered too, hence the change of the

fa465739d4 toshiba_acpi: Add a check for TOS_NOT_SUPPORTED in the sci_open function
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.

e26ffe5124 toshiba_acpi: Add support for USB Sleep and Charge function
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.

805469053b toshiba_acpi: Add keyboard backlight mode change event
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.

71454d78d3 toshiba_acpi: Change notify funtion to handle more events
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.

1f28f2908e toshiba_acpi: Move hotkey enabling code to its own function
The hotkey enabling code is being used by *_setup_keyboard and also by
*_resume.

This patch creates a new function called toshiba_acpi_enable_hotkeys to
be used by these two functions to avoid duplicating code.

63a9e016e8 toshiba-acpi: Add missing ID (TOS6207)
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 135740de77 ("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.

Tested on Toshiba Portege R100.

0098181016 platform: x86: Deletion of checks before backlight_device_unregister()
The backlight_device_unregister() function tests whether its argument is NULL
and then returns immediately. Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.

a39f46df33 toshiba_acpi: Fix regression caused by backlight extra check code
Bug 86521 uncovered that some TOS6208 devices also return
non zero values on a write call to the backlight method,
thus getting caught and bailed out by the extra check code.

This patch changes the set_lcd_brightness function to its
"original" state by just adapting it to the new function
format.

98280374ff drivers: platform: change 0x20 to I8042_STR_AUXDATA in i8042 filters
Instead of using a magic constant 0x20 in some drivers to get data only
from the KBC port we should use the constant defined in i8042.h with
the same value. Also, this makes these drivers uniform with what
constant the only other filter function uses in
drivers/input/misc/ideapad_slidebar.c.

893f3f62dc toshiba_acpi: Change HCI/SCI functions return code type
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.

1864bbc207 toshiba_acpi: Unify return codes prefix from HCI/SCI to TOS
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.

This patch changes the prefix of the return codes
definitions, dropping the HCI/SCI naming and instead
replacing it with TOS (for TOShiba).
