f2d8b4a3b3 binder_alloc: Avoid page memory allocation in high memory
In binder, using GFP_HIGHMEM will result in the allocated memory
not to be mapped in the kernel's virtual address space.
This prevents the kernel from being capable of directly
referring it.

9988a7c94c phy: mapphone-mdm6600: Fix pinctrl_pm handling for sleep pins
[ Upstream commit 3b384cc74b00b5ac21d18e4c1efc3c1da5300971 ]

Looks like the driver sleep pins configuration is unusable. Adding the
sleep pins causes the usb phy to not respond. We need to use the default
pins in probe, and only set sleep pins at phy_mdm6600_device_power_off().

As the modem can also be booted to a serial port mode for firmware
flashing, let's make the pin changes limited to probe and remove. For
probe, we get the default pins automatically. We only need to set the
sleep pins in phy_mdm6600_device_power_off() to prevent the modem from
waking up because the gpio line glitches.

If it turns out that we need a separate state for phy_mdm6600_power_on()
and phy_mdm6600_power_off(), we can use the pinctrl idle state.

de2c5bb086 platform/x86: asus-wmi: Map 0x2a code, Ignore 0x2b and 0x2c events
commit 235985d1763f7aba92c1c64e5f5aaec26c2c9b18 upstream.

Newer Asus laptops send the following new WMI event codes when some
of the F1 - F12 "media" hotkeys are pressed:

0x2a Screen Capture
0x2b PrintScreen
0x2c CapsLock

Map 0x2a to KEY_SELECTIVE_SCREENSHOT mirroring how similar hotkeys
are mapped on other laptops.

PrintScreem and CapsLock are also reported as normal PS/2 keyboard events,
map these event codes to KE_IGNORE to avoid "Unknown key code 0x%x\n" log
messages.

17b159cc55 platform/x86: asus-wmi: Change ASUS_WMI_BRN_DOWN code from 0x20 to 0x2e
commit f37cc2fc277b371fc491890afb7d8a26e36bb3a1 upstream.

Older Asus laptops change the backlight level themselves and then send
WMI events with different codes for different backlight levels.

The asus-wmi.c code maps the entire range of codes reported on
brightness down keypresses to an internal ASUS_WMI_BRN_DOWN code:

define NOTIFY_BRNUP_MIN                0x11
define NOTIFY_BRNUP_MAX                0x1f
define NOTIFY_BRNDOWN_MIN              0x20
define NOTIFY_BRNDOWN_MAX              0x2e

        if (code >= NOTIFY_BRNUP_MIN && code <= NOTIFY_BRNUP_MAX)
                code = ASUS_WMI_BRN_UP;
        else if (code >= NOTIFY_BRNDOWN_MIN && code <= NOTIFY_BRNDOWN_MAX)
                code = ASUS_WMI_BRN_DOWN;

Before this commit all the NOTIFY_BRNDOWN_MIN - NOTIFY_BRNDOWN_MAX
aka 0x20 - 0x2e events were mapped to 0x20.

This mapping is causing issues on new laptop models which actually
send 0x2b events for printscreen presses and 0x2c events for
capslock presses, which get translated into spurious brightness-down
presses.

The plan is disable the 0x11-0x2e special mapping on laptops
where asus-wmi does not register a backlight-device to avoid
the spurious brightness-down keypresses. New laptops always send
0x2e for brightness-down presses, change the special internal
ASUS_WMI_BRN_DOWN value from 0x20 to 0x2e to match this in
preparation for fixing the spurious brightness-down presses.

This change does not have any functional impact since all
of 0x20 - 0x2e is mapped to ASUS_WMI_BRN_DOWN first and only
then checked against the keymap code and the new 0x2e
value is still in the 0x20 - 0x2e range.

commit 0c21a18d5d6c6a73d098fb9b4701572370942df9 upstream.

acpi_register_gsi() should return a negative value in case of failure.

Currently, it returns the return value from irq_create_fwspec_mapping().
However, irq_create_fwspec_mapping() returns 0 for failure. Fix the
issue by returning -EINVAL if irq_create_fwspec_mapping() returns zero.

7a057ceeb5 mmc: core: Capture correct oemid-bits for eMMC cards
commit 84ee19bffc9306128cd0f1c650e89767079efeff upstream.

The OEMID is an 8-bit binary number rather than 16-bit as the current code
parses for. The OEMID occupies bits [111:104] in the CID register, see the
eMMC spec JESD84-B51 paragraph 7.2.3. It seems that the 16-bit comes from
the legacy MMC specs (v3.31 and before).

Let's fix the parsing by simply move to use 8-bit instead of 16-bit. This
means we ignore the impact on some of those old MMC cards that may be out
there, but on the other hand this shouldn't be a problem as the OEMID seems
not be an important feature for these cards.

commit 3a4a893dbb19e229db3b753f0462520b561dee98 upstream.

The NAND core complies with the ONFI specification, which itself
mentions that after any program or erase operation, a status check
should be performed to see whether the operation was finished *and*
successful.

The NAND core offers helpers to finish a page write (sending the
"PAGE PROG" command, waiting for the NAND chip to be ready again, and
checking the operation status). But in some cases, advanced controller
drivers might want to optimize this and craft their own page write
helper to leverage additional hardware capabilities, thus not always
using the core facilities.

Some drivers, like this one, do not use the core helper to finish a page
write because the final cycles are automatically managed by the
hardware. In this case, the additional care must be taken to manually
perform the final status check.

Let's read the NAND chip status at the end of the page write helper and
return -EIO upon error.

52df3caa47 net/mlx5: Handle fw tracer change ownership event based on MTRC
[ Upstream commit 92fd39634541eb0a11bf1bafbc8ba92d6ddb8dba ]

Currently, whenever fw issues a change ownership event, the PF that owns
the fw tracer drops its ownership directly and the other PFs try to pick
up the ownership via what MTRC register suggests.

In some cases, driver releases the ownership of the tracer and reacquires
it later on. Whenever the driver releases ownership of the tracer, fw
issues a change ownership event. This event can be delayed and come after
driver has reacquired ownership of the tracer. Thus the late event will
trigger the tracer owner PF to release the ownership again and lead to a
scenario where no PF is owning the tracer.

To prevent the scenario described above, when handling a change
ownership event, do not drop ownership of the tracer directly, instead
read the fw MTRC register to retrieve the up-to-date owner of the tracer
and set it accordingly in driver level.

In the pathological case of building sky2 with 16k PAGE_SIZE, the
frag_addr[] array would never be used, so the original code was correct
that size should be 0. But the compiler now gets upset with 0 size arrays
in places where it hasn't eliminated the code that might access such an
array (it can't figure out that in this case an rx skb with fragments
would never be created). To keep the compiler happy, make sure there is
at least 1 frag_addr in struct rx_ring_info:

[ Upstream commit 9e8bc2dda5a7a8e2babc9975f4b11c9a6196e490 ]

As timbgpio_irq_enable()/timbgpio_irq_disable() callback could be
executed under irq context, it could introduce double locks on
&tgpio->lock if it preempts other execution units requiring
the same locks.

timbgpio_gpio_set()
--> timbgpio_update_bit()
--> spin_lock(&tgpio->lock)
<interrupt>
   --> timbgpio_irq_disable()
   --> spin_lock_irqsave(&tgpio->lock)

This flaw was found by an experimental static analysis tool I am
developing for irq-related deadlock.

To prevent the potential deadlock, the patch uses spin_lock_irqsave()
on &tgpio->lock inside timbgpio_gpio_set() to prevent the possible
deadlock scenario.

4faed15c0e usb: typec: altmodes/displayport: Signal hpd low when exiting mode
[ Upstream commit 89434b069e460967624903b049e5cf5c9e6b99b9 ]

Upon receiving an ACK for a sent EXIT_MODE message, the DisplayPort
driver currently resets the status and configuration of the port partner.
The hpd signal is not updated despite being part of the status, so the
Display stack can still transmit video despite typec_altmode_exit placing
the lanes in a Safe State.

Set hpd to low when a sent EXIT_MODE message is ACK'ed.

040a07667f drm/connector: Add support for out-of-band hotplug notification (v3)
[ Upstream commit 72ad49682dde3d9de5708b8699dc8e0b44962322 ]

Add a new drm_connector_oob_hotplug_event() function and
oob_hotplug_event drm_connector_funcs member.

On some hardware a hotplug event notification may come from outside the
display driver / device. An example of this is some USB Type-C setups
where the hardware muxes the DisplayPort data and aux-lines but does
not pass the altmode HPD status bit to the GPU's DP HPD pin.

In cases like this the new drm_connector_oob_hotplug_event() function can
be used to report these out-of-band events.

Changes in v2:
- Make drm_connector_oob_hotplug_event() take a fwnode as argument and
  have it call drm_connector_find_by_fwnode() internally. This allows
  making drm_connector_find_by_fwnode() a drm-internal function and
  avoids code outside the drm subsystem potentially holding on the
  a drm_connector reference for a longer period.

Changes in v3:
- Drop the data argument to the drm_connector_oob_hotplug_event
  function since it is not used atm. This can be re-added later when
  a use for it actually arises.

[ Upstream commit 3d3f7c1e68691574c1d87cd0f9f2348323bc0199 ]

Add a function to find a connector based on a fwnode.

This will be used by the new drm_connector_oob_hotplug_event()
function which is added by the next patch in this patch-set.

Changes in v2:
- Complete rewrite to use a global connector list in drm_connector.c
  rather then using a class-dev-iter in drm_sysfs.c

Changes in v3:
- Add forward declaration for struct fwnode_handle to drm_crtc_internal.h
  (fixes warning reported by kernel test robot <lkp@intel.com>)

767af72d23 drm/connector: Add a fwnode pointer to drm_connector and register with ACPI (v2)
[ Upstream commit 48c429c6d18db115c277b75000152d8fa4cd35d0 ]

Add a fwnode pointer to struct drm_connector and register an acpi_bus_type
for the connectors with the ACPI subsystem (when CONFIG_ACPI is enabled).

The adding of the fwnode pointer allows drivers to associate a fwnode
that represents a connector with that connector.

When the new fwnode pointer points to an ACPI-companion, then the new
acpi_bus_type will cause the ACPI subsys to bind the device instantiated
for the connector with the fwnode by calling acpi_bind_one(). This will
result in a firmware_node symlink under /sys/class/card#-<connecter-name>/
which helps to verify that the fwnode-s and connectors are properly
matched.

Changes in v2:
- Make drm_connector_cleanup() call fwnode_handle_put() on
  connector->fwnode and document this

Give connector sysfs devices there own device_type, this allows us to
check if a device passed to functions dealing with generic devices is
a drm_connector or not.

A check like this is necessary in the drm_connector_acpi_bus_match()
function added in the next patch in this series.
