Like some of the other Yoga models the Lenovo Yoga 900 does not have a
hw rfkill switch, and trying to read the hw rfkill switch through the
ideapad module causes it to always reported blocking breaking wifi.
This commit adds the Lenovo Yoga 900 to the no_hw_rfkill dmi list, fixing
the wifi breakage.

This changes the entry to the whitelist of machines that do not have
a physical rfkill switch. Unfortunately, the Yoga 3 generation seems
to use upper-case letters for the YOGA 3 Pro-1370, while it uses normal
capitalization for its Yoga 3 1170 and 1470 siblings.
In order to catch all variants of the Yoga 3, I'm changing both
the entry for the 1470 (using "Yoga" as the name) and the entry for
the Pro 1370 (using all-caps "YOGA") to not match the exact model number
but only the generation. This way, the 1170 and 1470 models share one
entry, but if the firmware changes from one format to the other, it will
still work.
The second entry for Yoga 2 Pro that was recently added for some
reason ended up not being added in alphanumeric order, and I'm
moving the Yoga 3 1470 entry down while making the change, so they
are sorted more logically.

The ideapad-laptop handles most special keys on various Lenovo Laptops
including the Yoga line. Unfortunately, the Yoga 3 11/13/14 models have
one important exception, which is the Fn-ESC combination.
On other Lenovo Laptops, this is FnLock, which switches the function keys
between the primary (Mute, Vol down, Vol up, ...) and the secondary (F1,
F2, F3, ...) behavior. On the new machines, FnLock is only available
through BIOS setup (possibly through a yet-to-be-implemented feature
in this driver) but not through Fn-ESC, but instead the ESC key itself
switched between ESC and a "Paper Display" app for Windows.
Unfortunately, that means that you can never have both ESC *and* the
function keys working at the same time without needing to press Fn on
one of them.
As pointed out in the official Lenovo Forum by dozens of users, this
makes the machine rather useless for any serious work [1].
I have now studied the ACPI DSDT one more time and found the event
that is generated for the ESC key. Unlike all other key events on this
machine, it is actually a WMI, while the other ones are read from the
embedded controller.
I am now installing a WMI notifier that uses the event number from the
WMI subsystem as the scancode. The only event number generated here is
'128', and that fits in nicely with the two existing ranges of scancodes
used by the EC: 0-15 for the 16-bit VPCCMD_R_VPC register, 16-17 for
the VPCCMD_R_NOVO register and 64-67 for VPCCMD_R_SPECIAL_BUTTONS.
The only sane way to handle this button (in absence of the Windows Paper
Display driver) seems to be to have it emit KEY_ESC, so that is what
I use as the default. Should any user ever want to overwrite the default,
they can install their own keymap.
To ensure that we can still build the driver without adding a CONFIG_WMI
dependency, all new code is enclosed in #ifdef.

There is at least one (mine) Yoga 2 Pro in existence that has incorrect
product version stored in DMI (reading as "INVALID"), causing it to not be
recognized as Yoga 2 by ideapad-laptop module, which in turn causes
non-existent hardware rfkills to be always reported as blocked.
This change adds a second check by board name, which is "Yoga2".
Looks like it also happens to be "INVALID" on some other Yoga 2 machines
where product version is correct instead, so the original check is left
intact to catch both cases.

This fixes a several year old regression that I found while trying
to get the Yoga 3 11 to work. The ideapad_rfk_set function is meant
to send a command to the embedded controller through ACPI, but
as of c1f73658ed, it sends the index of the rfkill device instead
of the command, and ignores the opcode field.
This changes it back to the original behavior, which indeed
flips the rfkill state as seen in the debugfs interface.

Lenovo G40-30 does not provide any physical radio switch to user.
Therefore disable the rfkill switch identically to the Yoga 2 approach.
(Note for later, models ids are sorted alphabetically).
Benefit is to make wireless available again without unloading module.
It was tested successfully on 4.1.0-rc1 base with this model:
(LENOVO_MT_80FY_BU_idea_FM_Lenovo G40-30).

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 is a follow-up patch to commit 49458e83082d ("ideapad-laptop:

message says. The actual commit differs from the patch posted at
https://www.mail-archive.com/platform-driver-x86@vger.kernel.org/msg05340.html
significantly, probably due to a bad merge conflict resolution. Fix up
the mess and constify the DMI table for real and fix the bogus

I've received a bug report from a user that the touchpad control part
of the ideapad-laptop ACPI interface does work for him on his
"Lenovo Yoga 2 13", and that this patch causes a regression for him.
Since it did not work for me when I had a "Lenovo Yoga 2 11" in my own
hands (loaned from a friend). It seems that this is a bit of hit and miss.
Since the result of having a false positive here is worse, then the minor
annoyance of a false touchpad disabled messages being shown after suspend /
resume on models (or is it firmware versions?) where the interface does not
work, simply revert the patch.
This reverts commit f79a901331a823ae370584b15cd39dd110b95a0a.

It seems that the same problems which lead to adding an rfkill blacklist and
putting the Lenovo Yoga 2 11 on it are also present on the Lenovo Yoga 2 13
and Lenovo Yoga 2 Pro too:
https://bugzilla.redhat.com/show_bug.cgi?id=1021036
https://forums.lenovo.com/t5/Linux-Discussion/Yoga-2-13-not-Pro-Linux-Warning/m-p/1517612
Testing has shown that the firmware rfkill settings are persistent over
reboots. So blacklisting the driver is not good enough, if the wifi is blocked
at the firmware level the wifi needs to be explictly unblocked through the
ideapad-laptop interface.
And at least on the Lenovo Yoga 2 13 the VPCCMD_RF register which on devices
with hardware kill switch reports the hardware switch state, needs to be
explictly set to 1 (radio enabled / not blocked).
So this patch does 3 things to get proper rfkill handling on these models:
1) Instead of blacklisting the rfkill functionality, which means that people
with a firmware blocked wifi get stuck in that situation, ignore the value
reported by the not present hardware rfkill switch, as this is what is causing
ideapad-laptop to wrongly report all radios as hardware blocks. But do register
the rfkill interfaces so that the user can soft [un]block them.
2) On models without a hardware rfkill switch, explictly set VPCCMD_RF to 1
3) Drop the " 11" postfix from the dmi match string, as the entire Yoga 2
series is affected.

This patch moves data allocated using kzalloc to managed data allocated
using devm_kzalloc and cleans now unnecessary kfrees in probe and remove
functions. The label sysfs_failed is removed as it is no longer
required. Also, linux/device.h is added to make sure the devm_*()
routine declarations are unambiguously available.
The following Coccinelle semantic patch was used for making the change:

The Lenovo Yoga 2 11 always reports everything as blocked, causing userspace
to not even try to use the wlan / bluetooth even though they work fine.
Note this patch also removes the "else priv->rfk[i] = NULL;" bit of the
rfkill initialization, it is not necessary as the priv struct is allocated
with kzalloc.

Replace direct inclusions of <acpi/acpi.h>, <acpi/acpi_bus.h> and
<acpi/acpi_drivers.h>, which are incorrect, with <linux/acpi.h>
inclusions and remove some inclusions of those files that aren't
necessary.
First of all, <acpi/acpi.h>, <acpi/acpi_bus.h> and <acpi/acpi_drivers.h>
should not be included directly from any files that are built for
CONFIG_ACPI unset, because that generally leads to build warnings about
undefined symbols in !CONFIG_ACPI builds. For CONFIG_ACPI set,
<linux/acpi.h> includes those files and for CONFIG_ACPI unset it
provides stub ACPI symbols to be used in that case.
Second, there are ordering dependencies between those files that always
have to be met. Namely, it is required that <acpi/acpi_bus.h> be included
prior to <acpi/acpi_drivers.h> so that the acpi_pci_root declarations the
latter depends on are always there. And <acpi/acpi.h> which provides
basic ACPICA type declarations should always be included prior to any other
ACPI headers in CONFIG_ACPI builds. That also is taken care of including
<linux/acpi.h> as appropriate.

This patch does two things,
1. enumerate the ideapad device node to platform bus.
2. convert the current driver from ACPI bus to platform bus.
Note, with this patch, the platform device node created by ACPI,
with the name VPC2004:00, is used as the parent device of
the input, backlight, rfkill sysfs class device.
Plus the ideapad_platform private sysfs attributes,
i.e. camera_power and fan_mode, are also moved to the new
platform device node.
The previous platform device node "ideapad" is removed.

The current code use ideapad_handle and ideapad_priv to store
some information for the ideapad device.
But as they are global/static variables, the driver will be broken
if there are more than one ideapad ACPI device node on a platform.
Although this does not happen for now and may not happen in the future,
but still, this is a software bug.
Remove these two variables in this patch.

parameter
As struct ideapad_private has all the information needed for any operations,
convert ideapad_register_rfkill()/ideapad_unregister_rfkill() and
ideapad_sync_touchpad_state() to use struct ideapad_private as the parameter,
to be consistent with the others.

The patch adds support for fan control button on Ideapad Z580. This is

The second argument of ACPI driver .remove() operation is only used
by the ACPI processor driver and the value passed to that driver
through it is always available from the given struct acpi_device
object's removal_type field. For this reason, the second ACPI driver
.remove() argument is in fact useless, so drop it.

CONFIG_HOTPLUG is going away as an option. As a result, the __dev*
markings need to be removed.
This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.
Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

The patch adds support for Lenovo IdeaPad Z570 laptop. It makes all special
keys working, adds possibility to control fan like Windows does, controls
Touchpad Disabled LED, toggles touchpad state via keyboard controller and
corrects touchpad behavior on resume from suspend. It is new, modified
version of patch. Now it does not depend on psmouse and does not need patching
of input subsystem.

Novo key is the Lenovo define key on every ideapads, which has two
definition. Long press and short click. Driver will report
KEY_PROG1 on short click and KEY_PROG2 when long press.
On pre-install OS for ideapads there are application waiting for
the event and there is no such application for Linux yet, so I
think to report KEY_PROG is fine in anyway.
Also change the scancode from hex to decimal because they are
related to vpc bit in notify function which is in decimal.
