* [PATCH v3 0/3] Basic DT support for Lenovo Miix 630
From: Jeffrey Hugo @ 2019-04-15 16:09 UTC (permalink / raw)

The Lenovo Miix 630 is one of three ARM based (specifically Qualcomm
MSM8998) laptops that comes with Windows, and seems to have a dedicated
following of folks intrested to get Linux up and running on it.
This series adds support for the basic functionality this is validated
towork using devicetree. Although the laptops do feed ACPI to Windows,
the existing MSM8998 support in mainline is DT based, so DT provides a
quick path to functionality while ACPI support is investigated.
The three devices are very similar, but do have differences in the set
of peripherals supported, so the idea is that the vast majority of the
support for all three can live in a common include, which should reduce
overall duplication. Adding support for the other two devices as a
follow on should involve minimal work.
The bleeding edge work for these laptops and work in progress can be
found at https://github.com/aarch64-laptops/prebuilt
v3:
-Changed "clam" to "clamshell"
-Defined a dt binding for the combo Elan keyboard + touchpad device
-Adjusted the HID quirk to be correct for dt boot
-Removed extranious comment in board dts
-Fixed board level compatible
v2:
-Changed "cls" to "clam" since feedback indicated "cls" is too opaque,
but
"clamshell" is a mouthfull. "clam" seems to be a happy medium.

So bascally the same results as with the edge-triggered interrupt patch/hack,
right?
Are you still using the edge-triggered interrupt patch, or just the new
patch Kai-Heng Feng provided.
To me it sounds like the patch Kai-Heng Feng provided at least removes
the need for the edge-triggered interrupt patch/hack and what remains to
be solved is the suspend/resume issues.

* [PATCH v5 2/2] Input: add Apple SPI keyboard and trackpad driver.
From: Ronald Tschalär @ 2019-04-15 8:13 UTC (permalink / raw)
To: Dmitry Torokhov, Henrik Rydberg, Andy Shevchenko, Andrzej Hajda,
Inki Dae, Greg Kroah-Hartman
Cc: Lukas Wunner, Federico Lorenzi, Laurent Pinchart, linux-input,
dri-devel, linux-kernel
In-Reply-To: <20190415081300.24831-1-ronald@innovation.ch>
The keyboard and trackpad on recent MacBook's (since 8,1) and
MacBookPro's (13,* and 14,*) are attached to an SPI controller instead
of USB, as previously. The higher level protocol is not publicly
documented and hence has been reverse engineered. As a consequence there
are still a number of unknown fields and commands. However, the known
parts have been working well and received extensive testing and use.
In order for this driver to work, the proper SPI drivers need to be
loaded too; for MB8,1 these are spi_pxa2xx_platform and spi_pxa2xx_pci;
for all others they are spi_pxa2xx_platform and intel_lpss_pci. For this
reason enabling this driver in the config implies enabling the above
drivers.

+/*
+ * The keyboard and touchpad controller on the MacBookAir6, MacBookPro12,
+ * MacBook8 and newer can be driven either by USB or SPI. However the USB
+ * pins are only connected on the MacBookAir6 and 7 and the MacBookPro12.
+ * All others need this driver. The interface is selected using ACPI methods:
+ *
+ * * UIEN ("USB Interface Enable"): If invoked with argument 1, disables SPI
+ * and enables USB. If invoked with argument 0, disables USB.
+ * * UIST ("USB Interface Status"): Returns 1 if USB is enabled, 0 otherwise.
+ * * SIEN ("SPI Interface Enable"): If invoked with argument 1, disables USB
+ * and enables SPI. If invoked with argument 0, disables SPI.
+ * * SIST ("SPI Interface Status"): Returns 1 if SPI is enabled, 0 otherwise.
+ * * ISOL: Resets the four GPIO pins used for SPI. Intended to be invoked with
+ * argument 1, then once more with argument 0.
+ *
+ * UIEN and UIST are only provided on models where the USB pins are connected.
+ *
+ * SPI-based Protocol
+ * ------------------
+ *
+ * The device and driver exchange messages (struct message); each message is
+ * encapsulated in one or more packets (struct spi_packet). There are two types
+ * of exchanges: reads, and writes. A read is signaled by a GPE, upon which one
+ * message can be read from the device. A write exchange consists of writing a
+ * command message, immediately reading a short status packet, and then, upon
+ * receiving a GPE, reading the response message. Write exchanges cannot be
+ * interleaved, i.e. a new write exchange must not be started till the previous
+ * write exchange is complete. Whether a received message is part of a read or
+ * write exchange is indicated in the encapsulating packet's flags field.
+ *
+ * A single message may be too large to fit in a single packet (which has a
+ * fixed, 256-byte size). In that case it will be split over multiple,
+ * consecutive packets.

* [PATCH v5 1/2] drm/bridge: sil_sii8620: make remote control optional.

In-Reply-To: <20190415081300.24831-1-ronald@innovation.ch>
commit d6abe6df706c (drm/bridge: sil_sii8620: do not have a dependency
of RC_CORE) changed the driver to select both RC_CORE and INPUT.
However, this causes problems with other drivers, in particular an input
driver that depends on MFD_INTEL_LPSS_PCI (to be added in a separate
commit):
drivers/clk/Kconfig:9:error: recursive dependency detected!
drivers/clk/Kconfig:9: symbol COMMON_CLK is selected by MFD_INTEL_LPSS
drivers/mfd/Kconfig:566: symbol MFD_INTEL_LPSS is selected by MFD_INTEL_LPSS_PCI
drivers/mfd/Kconfig:580: symbol MFD_INTEL_LPSS_PCI is implied by KEYBOARD_APPLESPI
drivers/input/keyboard/Kconfig:73: symbol KEYBOARD_APPLESPI depends on INPUT
drivers/input/Kconfig:8: symbol INPUT is selected by DRM_SIL_SII8620
drivers/gpu/drm/bridge/Kconfig:83: symbol DRM_SIL_SII8620 depends on DRM_BRIDGE
drivers/gpu/drm/bridge/Kconfig:1: symbol DRM_BRIDGE is selected by DRM_PL111
drivers/gpu/drm/pl111/Kconfig:1: symbol DRM_PL111 depends on COMMON_CLK
According to the docs and general consensus, select should only be used
for non user-visible symbols, but both RC_CORE and INPUT are
user-visible. Furthermore almost all other references to INPUT
throughout the kernel config are depends, not selects. For this reason
the first part of this change reverts commit d6abe6df706c.
In order to address the original reason for commit d6abe6df706c, namely
that not all boards use the remote controller functionality and hence
should not need have to deal with RC_CORE, the second part of this
change now makes the remote control support in the driver optional and
contingent on RC_CORE being defined. And with this the hard dependency
on INPUT also goes away as that is only needed if RC_CORE is defined
(which in turn already depends on INPUT).

* [PATCH v5 0/2] Add Apple SPI keyboard and trackpad driver
From: Ronald Tschalär @ 2019-04-15 8:12 UTC (permalink / raw)

This changeset adds a driver for the SPI keyboard and trackpad on recent
MacBook's and MacBook Pro's. The driver has seen a fair amount of use
over the last 2 years (basically anybody running linux on these
machines), with only relatively small changes in the last year or so.
For those interested, the driver development has been hosted at
https://github.com/cb22/macbook12-spi-driver/ (as well as my clone at
https://github.com/roadrunner2/macbook12-spi-driver/).
The first patch fixes a problem during config.
The second patch contains the new applespi driver.
Changes in v5:
Applied all feedback from review by Andy Shevchenko (applespi) and
Andrzej Hajda (sil-sii8620), including:
- (sil_sii8620) use 'if (IS_DEFINED(...))' instead of conditional
compilation to handle RC_CORE being undefined
- (applespi) a number of cleanups of leftovers from changes to earlier
versions
- (applespi) replace some bool flags with loop-end detection
- (applespi) improve error reporting in a couple places
The full set of changes to applespi can be viewed at
https://github.com/roadrunner2/macbook12-spi-driver/ as individual
commits daf60f8..36afd70 in the upstreaming-review branch.

This works for me (with RC_CORE replaced with CONFIG_RC_CORE). Sending
a new patch that includes this shortly.

Hi Jonathan and Nikolaus,
I would like to jump into this discussion a bit as well. Might be
slightly off topic or not... I'm not too familiar with the details of
IIO, but as Sony we do report accelerometer / gyroscope data through
/dev/input for our DualShock devices through hid-sony. This is among
reasons done for Android, which Nikolaus showed interest in as well.
We are working on exposing this data through user space through
standard Android APIs (see,
https://android-review.googlesource.com/c/platform/hardware/libhardware/+/571762/).
The work will likely be merged later this year and it is already used
in some devices. Main reason it wasn't merged yet it that in our case
we have multiple evdev devices (gamepad, touchpad, motion sensors) and
need to tie those together for applications. Android doesn't support a
good mechanism for that yet.
Since the IIO input work relates to our Android work as well, I will
jump in more from the sidelines to make sure things are done in a
consistent manner. The main concern are resolution and value ranges.
Thanks,
Roderick

m/s^2 is conceptually right, but others have been using 'g' for input,
so I would consider that the standard now. Also leaves handling of
location on Earth to user space instead of assuming a fixed conversion
to 9.81 m/s^2.

We at the time were one of the first to expose acceleration and gyro
data through /dev/input for DualShock 4 as supported by hid-sony. We
report acceleration in 'g' and angular velocity in 'degree / s'. We
set the resolution to respectively '1 g' and '1 degree / s'. The range
we set to the range of the device e.g. for DS4 -4g to +4g for
acceleration. I need to check though what coordinate system we use,
but I think it is right handed (gyro counter clockwise relative to
acceleration axes).
The two other drivers using INPUT_PROC_ACCELEROMETER are hid-wacom and
hid-udraw-ps3 Wacom. Both seem to report resolution in 'g' as well.

Two main things:
1) Lack of generality of the approach.
This is a single use trick for input devices. Why does it make sense for
input devices? There are lots of other in kernel users and potential
ones in the future. The ability to register additional IIO consumers like
this is useful, lets make it useful to everyone.
2) To much generality of the specific usecase. I don't want to put an Input
interface on accelerometers where it makes no sense. The rule of it has
2-3 axis so it must make sense isn't good enough to my mind. How
does userspace know which accelerometer to use (more and more devices have
multiple?) You could do something like looking at the location info from
DT / ACPI in your driver and pick the 'best' but that's policy. Should be
in userspace. Sure you can just use the right input driver, but the moment
we do that, we need aware userspace, if that's the case why not make it
aware from the start.
Believe me I've been round this one a good few times and thought about it
a lot. I'll take a lot of convincing that this isn't a problem that
should be pushed into userspace.

Agreed, in the ideal case we wouldn't have had that either, but we are
stuck with it. The long term plan is to allow use of IIO backends without the
front end being there at all. Lots of SoC ADC users would prefer this. We are
stuck with the legacy intertwining fo the front end and back end of IIO so
this isn't as easy to do as I would like.

That argument does not apply. If we add a config option, distros will enable it.
So the vast majority of systems will ship with this turned on. You cannot
use a config variable to control policy and expect it to be change by anyone
but a very very small subset of users. So please drop the 'you can just not
build it argument'.
Userspace configuration changing is a lot easier if people actually care.
Sure, many distros will ship the same script to everyone.

Trivial resources and actually fairly trivial complexity. Key thing is
it puts the burden on the users of this functionality to configure what they
want.

Agreed, we just have a different view on how this should be done. I want
it to be dynamic and extremely flexible, you want the easy way of just
putting a fixed set out all the time.

Or, you an have the correct 'fairly trivial' userspace setup to scan for all
registered accelerometers and 'on demand' create the bindings to bring them up as
Input accelerometers if that is what makes sense for your platform.

No more that it needs to know which accelerometer to use?

No. Let me give some more details of how this would work. It's really just
a more flexible version of what you have.
A distro, or individual user decides to put the relevant script in place for the
following:
1. Userspace detects a new accelerometer driver, via the standard methods (uevent)
2. Userspace looks to see if it has the required properties. Now this includes things
like detecting that it is the accelerometer in the lid of a laptop - if so do not
register it as an input device. If it's in the keyboard then do register it.
3. Userspace script then creates the files in configfs
/sys/kernel/config/iio/maps/
(this interface needs appropriate definition)
Maybe...
/sys/kernel/config/iio/maps/iio_input/iio_device:X/accel_x, accel_y, etc
When done it writes to the bind file
/sys/kernel/config/iio/maps/iio_input/iio_device:X/bind
which instantiates the input driver.
This moves all of the policy decision into userspace, where it belongs. If
we want to enable a particular accelerometer on a particular board because it
actually works better than the one the default policy says to use, then we can
do so.
The resulting infrastructure is much more general, because it lets us do the
same for any IIO consumer. This input bridge is not a special case. It works
equally well for the existing hwmon bridge any would even let us do things
like provide the information from userspace that we have an analog accelerometer
wired up to an ADC on some hacker board.

See above. It's not the input accelerometer ABI, it's the missing ability

Yes we should. You are proposing a solution that is a subset of the larger
problem set. Why introduce a stop gap like this when we can do it correctly
and provide something useful for all those other use cases.
The only difference here is the uevent triggered script that creates those maps
for your particular usecase.

That is true for the narrow case you are talking about. I don't want to see that
narrow case solved in a fashion that effectively breaks solving it properly.
If we add this, we have to export all accelerometers for ever under all circumstances
to userspace, because to remove it will break existing userspace.
If we stand back and work out if we can do the general solution now, we avoid
this problem.

Hmm. I can see we perhaps need some mapping, but is there a concept of standard scale
for existing input accelerometers? How is this done to give for other input devices
such as touch screens? I'd expect to see a separation between scale, and range.

Agreed, it needs to be hardware independent by the time it hits userspace, but I would
have thought that scaling would be done in input, rather than IIO. It's hardly
a problem unique to our usecase!

Use fixed size. The worst that happens is we end up with it being
an entry larger that it needs to be.

Well we disagree on this. A singleton approach like used here
is to my mind not KISS. I would rather see what is there then
act as two simple steps, rather than interleave two different
actions with a totally different path for the first channel found.
If there is only one channel you just built a load of infrastructure
that makes no sense. If you scan first then you can know that
before building anything.

There is one compiling error in u2fzero_probe()->u2fzero_init_hwrng(),
this is because HW_RANDOM is not set.

Does the patch fix the other two issues:
- Five finger tap kill's module so you have to restart it;
- Two finger scoll is working incorrect and sometimes even when you
raised one of two finger still thinks that you are scrolling.

+* GPIO vibrator device tree bindings
+
+Registers a GPIO device as vibrator, where the vibration motor just has the
+capability to turn on or off. If the device is connected to a pwm, you should
+use the pwm-vibrator driver instead.
+
+Required properties:
+- compatible: should contain "gpio-vibrator"
+- enable-gpios: Should contain a GPIO handle
+
+Optional properties:
+- vcc-supply: Phandle for the regulator supplying power
+
+Example from Fairphone 2:
+
+vibrator {
+ compatible = "gpio-vibrator";
+ enable-gpios = <&msmgpio 86 GPIO_ACTIVE_HIGH>;
+ vcc-supply = <&pm8941_l18>;

Considering this is probably the only platform to have that RTC and that
is probably not worth having a better fix for a platform this old:

I guess. And defining these as 'input' is good because we do have
similar property names already for battery current limit and voltages.

Can you try below fix?
This can solve what commit 1475af255e18 ("HID: i2c-hid: Ignore input report
if there's no data present on Elan touchpanels”) tries to workaround.
