75f6dfe3e6 drm: Deduplicate driver initialization message
Several DRM drivers print the same initialization message right after
drm_dev_register, so move that to common code.  The exception is i915,
which uses its own register handle, so let it keep its own message.

Notice that this was tested only with Exynos, but looks simple enough
for the other drivers.

d96324703f rt2x00: merge agc and vco works with link tuner
We need to perform different actions (AGC and VCO calibrations and VGC
tuning) periodically at different intervals. We don't need separate
works for those, we can use link tuner work and just check for proper
interval on it.

This fixes performing AGC and VCO calibration when scanning on STA
mode. We need to be on-channel to perform those calibrations.

8f03a7c6e7 rt2800: set MAX_PSDU len according to remote STAs capabilities
MAX_LEN_CFG_MAX_PSDU specify maximum transmitted by HW AMPDU length
(0 - 8kB, 1 - 16kB, 2 - 32kB, 3 - 64kB). Set this option according to
remote stations capabilities (based on HT ampdu_factor). However limit
the value based our hardware TX capabilities as some chips can not send
more than 16kB (factor 1). Limit for all chips is currently 32kB
(factor 2), but perhaps for some chips this could be increased
to 64kB by setting drv_data->max_psdu to 3.

Since MAX_LEN_CFG_MAX_PSDU is global setting, on multi stations modes
(AP, IBSS, mesh) we limit according to less capable remote STA. We can
not set bigger value to speed up communication with some stations and
do not break communication with slow stations.

ae3cf47645 iwlegacy: make il3945_mac_ops __ro_after_init
There's no need for this to be only __read_mostly, since
it's only written in a single way depending on the module
parameter, so that can be moved into the module's __init
function, and the ops can be __ro_after_init.

This is a little bit safer since it means the ops can't
be overwritten (accidentally or otherwise), which would
otherwise cause an arbitrary function or bad pointer to
be called.

a0c10687ec Revert "remoteproc: Merge table_ptr and cached_table pointers"
Following any fw_rsc_vdev entries in the resource table are two variable
length arrays, the first one reference vring resources and the second
one is the virtio config space.  The virtio config space is used by
virtio to communicate status and configuration changes and must as such
be shared with the remote.

The reverted commit incorrectly made any changes to the virtio config
space only affect the local copy, in an attempt to allowing memory
protection of the shared resource table.

This reverts commit cda8529346.

c81c0e0710 remoteproc: fix vdev reference management
Commit 2b45cef586 ("remoteproc: Further extend the vdev life cycle")
extends kref support for vdev management.
It introduces a regression when following sequence is executed:
rproc_boot --> rproc_shutdown --> rproc_boot
Second rproc_boot call crashes on register_virtio_device as device
is already existing.
Issue is previous vdev is never released when rproc is stop because
associated refcount is too high.

kref_get introduces is not needed as kref_init already initializes
krefcount to 1 because it considers associated variable as used.
This introduces a misalignment between kref_get and kref_put calls.

Since commit 4dffed5b3a ("rpmsg: Name rpmsg devices based on

a service (on different endpoints). rpmsg_register_device function
is failing when calling device_add for the second time as second
device has the same name as first one already register.
It is because name is based only on service name and so is not more
unique. Previously name was unique thanks to the use of rpmsg_dev_index.

This patch adds destination and source endpoint numbers device name to
create an unique identifier.

d679fa1b3c ath10k: recal the txpower when removing interface
The txpower is being recalculated when adding interface to make sure
txpower won't overshoot the spec, and when removing the interface,
the txpower should again to be recalculated to restore the correct value
from the active interface list.

Following is one of the scenario
	vdev0 is created as STA and connected: txpower:23
	vdev1 is created as P2P_DEVICE for control interface: txpower:0
	vdev2 is created as p2p go/gc interface: txpower is 21

So the vdev2@txpower:21 will be set to firmware when vdev2 is created.
When we tear down the vdev2, the txpower needs to be recalculated to
re-set it to vdev0@txpower:23 as vdev0/vdev1 are the active interface.

	ath10k_pci mac vdev 0 peer create 8c:fd:f0:01:62:98
	ath10k_pci mac vdev_id 0 txpower 23
	... (adding interface)
	ath10k_pci mac vdev create 2 (add interface) type 1 subtype 3
	ath10k_pci mac vdev_id 2 txpower 21
	ath10k_pci mac txpower 21
	... (removing interface)
	ath10k_pci mac vdev 2 delete (remove interface)
	ath10k_pci vdev 1 txpower 0
	ath10k_pci vdev 0 txpower 23
	ath10k_pci mac txpower 23

727000e6af ath10k: support dev_coredump for crash dump
Whenever firmware crashes, and both CONFIG_ATH10K_DEBUGFS and
CONFIG_ALLOW_DEV_COREDUMP are enabled, dump information about the crash via a
devcoredump device. Dump can be read from userspace for further analysis from:

/sys/class/devcoredump/devcd*/data

As until now we have provided the firmware crash dump file via fw_crash_dump
debugfs keep it still available but deprecate and a warning print that the user
should switch to using dev_coredump.

Future improvement would be not to depend on CONFIG_ATH10K_DEBUGFS, as there
might be systems which want to get the firmware crash dump but not enable
debugfs. How to handle memory consumption is also something which needs to be
taken into account.

88407beb1b ath10k: fix incorrect txpower set by P2P_DEVICE interface
Ath10k reports the phy capability that supports P2P_DEVICE interface.

When we use the P2P supported wpa_supplicant to start connection, it'll
create two interfaces, one is wlan0 (vdev_id=0) and one is P2P_DEVICE
p2p-dev-wlan0 which is for p2p control channel (vdev_id=1).

	ath10k_pci mac vdev create 0 (add interface) type 2 subtype 0
	ath10k_add_interface: vdev_id: 0, txpower: 0, bss_power: 0
	...
	ath10k_pci mac vdev create 1 (add interface) type 2 subtype 1
	ath10k_add_interface: vdev_id: 1, txpower: 0, bss_power: 0

And the txpower in per vif bss_conf will only be set to valid tx power when
the interface is assigned with channel_ctx.

But this P2P_DEVICE interface will never be used for any connection, so
that the uninitialized bss_conf.txpower=0 is assinged to the
arvif->txpower when interface created.

Since the txpower configuration is firmware per physical interface.
So the smallest txpower of all vifs will be the one limit the tx power
of the physical device, that causing the low txpower issue on other
active interfaces.

	wlan0: Limiting TX power to 21 (24 - 3) dBm
	ath10k_pci mac vdev_id 0 txpower 21
	ath10k_mac_txpower_recalc: vdev_id: 1, txpower: 0
	ath10k_mac_txpower_recalc: vdev_id: 0, txpower: 21
	ath10k_pci mac txpower 0

This issue only happens when we use the wpa_supplicant that supports
P2P or if we use the iw tool to create the control P2P_DEVICE interface.

ath10k_wmi_tlv_op_pull_fw_stats() uses tb = ath10k_wmi_tlv_parse_alloc(...)
function, which allocates memory. If any of the three error-paths are
taken, this tb needs to be freed.

b1eb8fabc8 pinctrl: simplify check for pin request conflicts
This is a non-functional change, which deletes code duplication in two
of four if-if branches by reordering the checks. Functional identity
of the code change can be shown by running through the whole truth table

a79fead50f gpio: of: Add support for multiple GPIOs in a single GPIO hog
When listing multiple GPIOs in the "gpios" property of a GPIO hog, only
the first GPIO is affected.  The user is left clueless about the
dysfunctioning of the other GPIOs specified.

Fix this by adding and documenting support for specifying multiple
GPIOs in a single GPIO hog.
