Arnd Bergmann c789fffc56 ideapad-laptop: include Yoga 3 1170 in add rfkill whitelist
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.

Arnd Bergmann 74caab996c ideapad-laptop: add support for Yoga 3 ESC key
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.

Sebastian Krzyszkowiak 6d212b8adc ideapad-laptop: add alternative representation for Yoga 2 to DMI table
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.

Arnd Bergmann 4b200b4604 ideapad: fix software rfkill setting
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.

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 f79a901331.

Hans de Goede ce363c2bcb ideapad-laptop: Change Lenovo Yoga 2 series rfkill handling
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.

Lv Zheng 8b48463f89 ACPI: Clean up inclusions of ACPI header files
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.

Zhang Rui b5c37b798f ideapad_laptop: convert ideapad device/driver to platform bus
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.

Zhang Rui 331e0ea243 ideapad_laptop: remove ideapad_handle and ideapad_priv
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.

On pre-install OS for ideapads there are application waiting for
