When the ideapad-laptop driver was first written it was written for laptops
which had a hardware rfkill switch. So when the first ideapad laptops
showed up without a hw rfkill switch and it turned out that in this case
the ideapad firmware interface would always report the wifi being hardware-
blocked, a DMI id list of models which lack a hw rfkill switch was started
(by yours truly). Things were done this way to avoid regressing existing
models with a hw rfkill switch. In hindsight this was a mistake.
Lenovo releases a lot of ideapad models every year and even the latest
models still use the "VPC2004" ACPI interface the ideapad-laptop driver
binds to. Having a hw rfkill switch is quite rare on modern hardware, so
all these new models need to be added to the no_hw_rfkill_list, leading
to a never ending game of whack a mole.
Worse the failure mode when not present on the list, is very bad. In this
case the ideapad-laptop driver will report the wifi as being hw-blocked,
at which points NetworkManager does not even try to use it and the user
ends up with non working wifi.
This leads to various Linux fora on the internet being filled with
wifi not working on ideapad laptops stories, which does not make Linux
look good.
The failure mode when we flip the default to assuming that a hw rfkill
switch is not present OTOH is quite benign. When we properly report the
wifi as being hw-blocked on ideapads which do have the hw-switch; and it
is in the wifi-off position, then at least when using NetworkManager +
GNOME3 the user will get a "wifi disabled in hardware" message when trying
to connect to the wifi from the UI. If OTOH we assume there is no hardware
rfkill switch, then the user will get an empty list for the list of
available networks. Although the empty list vs the "wifi disabled in
hardware" message is a regression, it is a very minor regression and it
can easily be fixed on a model by model basis by filling the new
hw_rfkill_list this commit introduces.
Therefor this commit removes the ever growing no_hw_rfkill_list, flipping
the default to assuming there is no hw rfkill switch and adding a new
hw_rfkill_list. Thereby fixing the wifi not working on all the current
ideapad and yoga models which are not on the list yet and also fixing it
for all future ideapad and yoga models using the "VPC2004" ACPI interface.
Note once this patch has been accepted upstream. I plan to write a blog
post asking for users of ideapads and yoga's with a hw rfkill switch to
step forward, so that we can populate the new hw_rfkill_list with the few
older yoga and ideapad models which actually have a hw rfkill switch.

On Ideapad laptops, ACPI event 1 is currently not handled. Many models
log "ideapad_laptop: Unknown event: 1" every 20 seconds or so while

when switching in and out of tablet mode.
This adds and additional case for event 1 in ideapad_acpi_notify to call
ideapad_input_report(priv, vpc_bit), so that the event is reported to
userspace and we avoid unnecessary logging.

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 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.
