Guenter Roeck 9ae11e237d platform/x86: intel_pmc_core: Mark local function static
0day reports:

drivers/platform/x86/intel_pmc_core.c:833:5: sparse:
	symbol 'quirk_xtal_ignore' was not declared. Should it be static?

Mark the function static since it is indeed only called locally.

Enric Balletbo i Serra e43c426a77 platform/chrome: cros_ec_debugfs: Remove dev_warn when console log is not supported
If the debugfs interface is enabled, every time a CrOS device is
instantiated a warning like this can appear for every probed device.

 "device does not support reading the console log"

The warning message adds nothing, rather it is source of confusion as
this is expected on some cases. For example, on Samus, that has a
cros-ec and a cros-pd instance the message appears twice, and I suspect
this will happen also on those devices that has a non-standard EC.

If the command is not supported just return silently and don't print the
warning, otherwise the code will already print an error.

If console logging is not supported, the work structure is never
initialized, resulting in the traceback. Calling cancel/schedule functions
conditionally fixes the problem.

While at it, also fix error handling in the probe function.

Linus Torvalds 3601fe43e8 This is the bulk of GPIO changes for the v5.1 cycle:
Core changes:
 
 - The big change this time around is the irqchip handling in
   the qualcomm pin controllers, closely coupled with the
   gpiochip. This rework, in a classic fall-between-the-chairs
   fashion has been sidestepped for too long. The Qualcomm
   IRQchips using the SPMI and SSBI transport mechanisms have
   been rewritten to use hierarchical irqchip. This creates
   the base from which I intend to gradually pull support for
   hierarchical irqchips into the gpiolib irqchip helpers to
   cut down on duplicate code. We have too many hacks in the
   kernel because people have been working around the missing
   hierarchical irqchip for years, and once it was there,
   noone understood it for a while. We are now slowly adapting
   to using it. This is why this pull requests include changes
   to MFD, SPMI, IRQchip core and some ARM Device Trees
   pertaining to the Qualcomm chip family. Since Qualcomm have
   so many chips and such large deployments it is paramount
   that this platform gets this right, and now it (hopefully)
   does.
 
 - Core support for pull-up and pull-down configuration, also
   from the device tree. When a simple GPIO chip support a
   "off or on" pull-up or pull-down resistor, we provide a
   way to set this up using machine descriptors or device tree.
   If more elaborate control of pull up/down (such as
   resistance shunt setting) is required, drivers should be

Merge tag 'gpio-v5.1-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio

Pull GPIO updates from Linus Walleij:
 "This is the bulk of GPIO changes for the v5.1 cycle:

  Core changes:

   - The big change this time around is the irqchip handling in the
     qualcomm pin controllers, closely coupled with the gpiochip. This
     rework, in a classic fall-between-the-chairs fashion has been
     sidestepped for too long.

     The Qualcomm IRQchips using the SPMI and SSBI transport mechanisms
     have been rewritten to use hierarchical irqchip. This creates the
     base from which I intend to gradually pull support for hierarchical
     irqchips into the gpiolib irqchip helpers to cut down on duplicate
     code.

     We have too many hacks in the kernel because people have been
     working around the missing hierarchical irqchip for years, and once
     it was there, noone understood it for a while. We are now slowly
     adapting to using it.

     This is why this pull requests include changes to MFD, SPMI,
     IRQchip core and some ARM Device Trees pertaining to the Qualcomm
     chip family. Since Qualcomm have so many chips and such large
     deployments it is paramount that this platform gets this right, and
     now it (hopefully) does.

   - Core support for pull-up and pull-down configuration, also from the
     device tree. When a simple GPIO chip supports an "off or on" pull-up
     or pull-down resistor, we provide a way to set this up using
     machine descriptors or device tree.

     If more elaborate control of pull up/down (such as resistance shunt
     setting) is required, drivers should be phased over to use pin
     control. We do not yet provide a userspace ABI for this pull
     up-down setting but I suspect the makers are going to ask for it
     soon enough. PCA953x is the first user of this new API.

   - The GPIO mockup driver has been revamped after some discussion
     improving the IRQ simulator in the process.

     The idea is to make it possible to use the mockup for both testing
     and virtual prototyping, e.g. when you do not yet have a GPIO
     expander to play with but really want to get something to develop
     code around before hardware is available. It's neat. The blackbox
     testing usecase is currently making its way into kernelci.

   - ACPI GPIO core preserves non direction flags when updating flags.

   - A new device core helper for devm_platform_ioremap_resource() is
     funneled through the GPIO tree with Greg's ACK.

  New drivers:

   - TQ-Systems QTMX86 GPIO controllers (using port-mapped I/O)

   - Gateworks PLD GPIO driver (vaccumed up from OpenWrt)

   - AMD G-Series PCH (Platform Controller Hub) GPIO driver.

   - Fintek F81804 & F81966 subvariants.

   - PCA953x now supports NXP PCAL6416.

  Driver improvements:

   - Set the right output level on SAMA5D2.

   - Drop the unused irq trigger setting on the Spreadtrum driver.

Linus Torvalds 45763bf4bc Char/Misc driver patches for 5.1-rc1
Here is the big char/misc driver patch pull request for 5.1-rc1.
 
 The largest thing by far is the new habanalabs driver for their AI
 accelerator chip.  For now it is in the drivers/misc directory but will
 probably move to a new directory soon along with other drivers of this
 type.
 
 Other than that, just the usual set of individual driver updates and
 fixes.  There's an "odd" merge in here from the DRM tree that they asked
 me to do as the MEI driver is starting to interact with the i915 driver,
 and it needed some coordination.  All of those patches have been
 properly acked by the relevant subsystem maintainers.
 
 All of these have been in linux-next with no reported issues, most for
 quite some time.

Arnd Bergmann 2794449576 platform/chrome: fix wilco-ec dependencies
When CROS_EC_LPC is set to =m, we get a link failure for a
builtin wilco-ec module:

drivers/platform/chrome/wilco_ec/core.o: In function `wilco_ec_remove':
core.c:(.text+0x26): undefined reference to `cros_ec_lpc_mec_destroy'

drivers/platform/chrome/wilco_ec/mailbox.o: In function `wilco_ec_mailbox':
mailbox.c:(.text+0x104): undefined reference to `cros_ec_lpc_io_bytes_mec'

The problem with the existing CROS_EC_LPC_MEC dependency is that this
is only for a 'bool' symbol, so the information about the exported
functions being in a module is lost on the way, and we actually have
to depend on both CROS_EC_LPC and CROS_EC_LPC_MEC.

Rajneesh Bhardwaj 238f9c1135 platform/x86: intel_pmc_core: Quirk to ignore XTAL shutdown
On some platforms such as HP Elite-x2-1013-g3, the platform BIOS
enforces XTAL to remain off before S0ix state can be achieved. This may
not be optimum when we want to enable use cases like Low Power Audio,
Wake on Voice etc which always need 24mhz clock.

This introduces a new quirk to allow S0ix entry when all other
conditions except for XTAL clock are good on a given platform. The extra
power consumed by XTAL clock is about 2mw but it saves much more
platform power compared to the system that remains in just PC10.

Rajneesh Bhardwaj 8aba056a4e platform/x86: intel_pmc_core: Add Package cstates residency info
This patch introduces a new debugfs entry to read current Package
cstate residency counters. A similar variant of this patch was discussed
earlier "https://patchwork.kernel.org/patch/9908563/" but didn't make it
into mainline for various reasons. Current version only adds debugfs
entry which is quite useful for S0ix debug but excludes the exported API
that was there in initial version. Though there are tools like turbostat
and socwatch which can also show this info but sometimes its more
practical to have it here as it's hard to switch between various tools for
S0ix debug when pmc_core driver is the primary debug tool. Internal and
external customers have requested for this patch to be included in the
PMC driver on many occasions and Google Chrome OS team has already included
it in their builds. This becomes handy when requesting logs from external
customers who may not always have above mentioned tools in their integrated
kernel builds.

Package cstate residency MSRs provide useful debug information about
system idle states. In idle states system must enter deeper Package
cstates. Package cstates depend not only on Core cstates but also on
various IP block's power gating status and LTR values.

For Intel Core SoCs Package C10 entry is a must for deeper sleep states
such as S0ix. "Suspend-to-idle"  should ideally take this path:
PC0 -> PC10 -> S0ix. For S0ix debug, its logical to check for
Package C10 residency first if for some reason system fails to enter S0ix.

Please refer to this link for MSR details:
https://software.intel.com/sites/default/files/managed/22/0d/335592-sdm-vol-4.pdf

Rajat Jain 4a5861f714 platform/x86: intel_pmc_core: Avoid a u32 overflow
The register (SLP_S0_RES) at offset slp_s0_offset is a 32 bit register.
The pmc_core_adjust_slp_s0_step() could overflow the u32 value while
returning it after adjusting the step. Thus change to u64, this is
already accounted for in debugfs attribute (that wants to output a
64 bit value).

The warning is caused by the below loop:
	for_each_set_bit(bit, (unsigned long *)&asserted, 8) {
while "asserted" is declared as 'unsigned'.

The casting of 32-bit unsigned integer pointer to a 64-bit unsigned long
pointer. There are two problems here.
It causes the access of four extra byte, which can corrupt memory
The 32-bit pointer address may not be 64-bit aligned.

The fix changes variable "asserted" to "unsigned long".

Commit ae7c8cba32 ("platform/x86: ideapad-laptop: add lenovo RESCUER
R720-15IKBN to no_hw_rfkill_list") added
    DMI_MATCH(DMI_BOARD_NAME, "80WW")
for Lenovo RESCUER R720-15IKBN.

But DMI_BOARD_NAME does not match 80WW on Lenovo RESCUER R720-15IKBN,
thus cause Wireless LAN still be hard blocked.

On Lenovo RESCUER R720-15IKBN:
    ~$ cat /sys/class/dmi/id/sys_vendor
    LENOVO
    ~$ cat /sys/class/dmi/id/board_name
    Provence-5R3
    ~$ cat /sys/class/dmi/id/product_name
    80WW
    ~$ cat /sys/class/dmi/id/product_version
    Lenovo R720-15IKBN

So on Lenovo RESCUER R720-15IKBN:
    DMI_SYS_VENDOR should match "LENOVO",
    DMI_BOARD_NAME should match "Provence-5R3",
    DMI_PRODUCT_NAME should match "80WW",
    DMI_PRODUCT_VERSION should match "Lenovo R720-15IKBN".

Fix it, and in according with other entries in no_hw_rfkill_list,
use DMI_PRODUCT_VERSION instead of DMI_BOARD_NAME.

Hans de Goede c994611aca platform/x86: asus-wmi: Allow loading on systems without the Asus Management GUID
hid-asus depends on asus-wmi through the asus_wmi_evaluate_method. Before
this commit asus-wmi, and thus hid-asus, could not be loaded on non-Asus
systems. This breaks using Asus bluetooth keyboards such as the Asus
T100CHI keyboard with non Asus systems.

This commit fixes this by allowing asus-wmi to load on systems without the
Asus Management GUID.

This is safe to do since all asus-wmi sub drivers use
asus_wmi_register_driver which also checks for the GUID.

This commit also improves the error messages in asus_wmi_register_driver
to include "ASUS" in their description to make them more clear. This is
important since we now rely on those errors when loaded on systems without
the Asus Management GUID.

Nick Crews 0d2f2a3da1 platform/chrome: wilco_ec: Add RTC driver
This Embedded Controller has an internal RTC that is exposed
as a standard RTC class driver with read/write functionality.

The driver is added to the drivers/rtc/ so that the maintainer of that
directory will be able to comment on this change, as that maintainer is
the expert on this system. In addition, the driver code is called
indirectly after a corresponding device is registered from core.c,
as opposed to core.c registering the driver callbacks directly.

To test:

Recently introduced commit "platform/x86: intel_pmc_core: Show Latency
Tolerance info <51337cd94d18184601ac0fb4cf1a02b8bbabc3d7> skipped the
LTR from a reserved IP. Though this doesn't cause any functional issue
but it is needed for the consumers of "ltr_ignore" as the index printing
for "ltr_show" is missing. For example, w/o this change, a user that wants
to ignore LTR from ME would do something like

echo 5 > ltr_ignore

but the index for ME is 6. Printing a reserved IP helps to properly
calculate LTR ignore offsets.

Nick Crews 6b7cb2227d platform/chrome: cros_ec: Remove cros_ec dependency in lpc_mec
In order to allow this code to be re-used, remove the dependency
on the rest of the cros_ec code from the cros_ec_lpc_mec functions.

Instead of using a hardcoded register base address of 0x800 have
this be passed in to cros_ec_lpc_mec_init().  The existing cros_ec
use case now passes in the 0x800 base address this way.

There are some error checks that happen in cros_ec_lpc_mec_in_range()
that probably shouldn't be there, as they are checking kernel-space
callers and not user-space input. However, we'll just do the refactor in
this patch, and in a future patch might remove this error checking and
fix all the instances of code that calls this.

There's a similar problem in cros_ec_lpc_read_bytes(), where we return a
checksum, but on error just return 0. This should probably be changed so
that it returns int, but we don't want to have to mess with all the
calling code for this fix. Maybe we'll come back through later and fix
this.

better abstraction to this driver but has some fundamental issues.

e.g. the following condition

for (index = 0; index < pmcdev->map->ppfear_buckets &&
	index < PPFEAR_MAX_NUM_ENTRIES; index++, iter++)

is wrong because for CNL, PPFEAR_MAX_NUM_ENTRIES is hardcoded as 5 which
is _wrong_ and even though ppfear_buckets is 8, the loop fails to read
all eight registers needed for CNL PCH i.e. PPFEAR0 and PPFEAR1. This
patch refactors the pfear show logic to correctly read PCH IP power
gating status for Cannonlake and beyond.

but this seems to be a copy and paste job from the BSG1160 firmware node
on other devices, since there is no i2c-client listening to the 0x68
address listed in the third resource and the 0x68 address is identical
to the address of the third resource in the BSG1160 nodes, where as the
other 2 addresses are different.

Add the ID to the I2C multi instantiate list, so that the
i2c-multi-instantiate.c driver can handle it;

And add the necessary info to the i2c-multi-instantiate.c driver to
enumerate all I2C slaves correctly.

To avoid triggering the:

        if (i < multi->num_clients) {
                dev_err(dev, "Error finding driver, idx %d\n", i);

Error this commit lists the 3th device in the i2c_inst_data with a
type of "bsg2150_dummy_dev".

Enric Balletbo i Serra fd68bd0f5d platform/chrome: cros_ec_lightbar: Instantiate only if the EC has a lightbar
Due to the way attribute groups visibility work, the function
cros_ec_lightbar_attrs_are_visible is called multiple times, once per
attribute, and each of these calls makes an EC transaction. For what is
worth the EC log reports multiple errors on boot when the lightbar is
not available. Instead, check if the EC has a lightbar in the probe
function and only instantiate the device.

Ideally we should have instantiate the driver only if the
EC_FEATURE_LIGHTBAR is defined, but that's not possible because that flag
is not in the very first Pixel Chromebook (Link), only on Samus. So, the
driver is instantiated by his parent always.

This patch changes a bit the actual behaviour. Before the patch if an EC
doesn't have a lightbar an empty lightbar folder is created in
/sys/class/chromeos/<ec-device-name>, after the patch the empty folder is
not created, so, the folder is only created if the lightbar exists.

Power button suspend for some Dell models was added in:

commit 821b853662 ("platform/x86: intel-hid: Power button suspend on Dell Latitude 7275")

by checking against the power button press notification (0xCE) to report
the power button press event. The corresponding power button release
notification (0xCF) was caught and ignored to stop it from being reported
as an "unknown event" in the logs.

The missing button release event is creating issues on Android-x86, as
reported on the project mailing list for a Dell Latitude 5175 model, since
the events are expected in down/up pairs.

Report the power button release event to fix this issue.

Linus Torvalds 96d4f267e4 Remove 'type' argument from access_ok() function
Nobody has actually used the type (VERIFY_READ vs VERIFY_WRITE) argument
of the user address range verification function since we got rid of the
old racy i386-only code to walk page tables by hand.

It existed because the original 80386 would not honor the write protect
bit when in kernel mode, so you had to do COW by hand before doing any
user access.  But we haven't supported that in a long time, and these
days the 'type' argument is a purely historical artifact.

A discussion about extending 'user_access_begin()' to do the range
checking resulted this patch, because there is no way we're going to
move the old VERIFY_xyz interface to that model.  And it's best done at
the end of the merge window when I've done most of my merges, so let's
just get this done once and for all.

This patch was mostly done with a sed-script, with manual fix-ups for
the cases that weren't of the trivial 'access_ok(VERIFY_xyz' form.

There were a couple of notable cases:

 - csky still had the old "verify_area()" name as an alias.

 - the iter_iov code had magical hardcoded knowledge of the actual
   values of VERIFY_{READ,WRITE} (not that they mattered, since nothing
   really used it)

 - microblaze used the type argument for a debug printout

but other than those oddities this should be a total no-op patch.

I tried to fix up all architectures, did fairly extensive grepping for
access_ok() uses, and the changes are trivial, but I may have missed
something.  Any missed conversion should be trivially fixable, though.

 Lots of different types of driver things in here, as this tree seems to
 be the "collection of various driver subsystems not big enough to have
 their own git tree" lately.
 
 Anyway, some highlights of the changes in here:
   - binderfs: is it a rule that all driver subsystems will eventually
     grow to have their own filesystem?  Binder now has one to handle the
     use of it in containerized systems.  This was discussed at the
     Plumbers conference a few months ago and knocked into mergable shape
     very fast by Christian Brauner.  Who also has signed up to be
     another binder maintainer, showing a distinct lack of good judgement :)
   - binder updates and fixes
   - mei driver updates
   - fpga driver updates and additions
   - thunderbolt driver updates
   - soundwire driver updates
   - extcon driver updates
   - nvmem driver updates
   - hyper-v driver updates
   - coresight driver updates
   - pvpanic driver additions and reworking for more device support
   - lp driver updates.  Yes really, it's _finally_ moved to the proper
     parallal port driver model, something I never thought I would see
     happen.  Good stuff.
   - other tiny driver updates and fixes.
 
 All of these have been in linux-next for a while with no reported

   - binderfs: is it a rule that all driver subsystems will eventually
     grow to have their own filesystem? Binder now has one to handle the
     use of it in containerized systems.

     This was discussed at the Plumbers conference a few months ago and
     knocked into mergable shape very fast by Christian Brauner. Who
     also has signed up to be another binder maintainer, showing a
     distinct lack of good judgement :)

   - binder updates and fixes

   - mei driver updates

   - fpga driver updates and additions

   - thunderbolt driver updates

   - soundwire driver updates

   - extcon driver updates

   - nvmem driver updates

   - hyper-v driver updates

   - coresight driver updates

   - pvpanic driver additions and reworking for more device support

   - lp driver updates. Yes really, it's _finally_ moved to the proper
     parallal port driver model, something I never thought I would see
     happen. Good stuff.

   - other tiny driver updates and fixes.

  All of these have been in linux-next for a while with no reported
  issues"
