220915857e Bluetooth: Adding driver and quirk defs for multi-role LE
This change adds the relevant driver and quirk to allow drivers to
report the le_states as being trustworthy.

This has historically been disabled as controllers did not reliably
support this. In particular, this will be used to relax this condition
for controllers that have been well tested and reliable.

	/* Most controller will fail if we try to create new connections
	 * while we have an existing one in slave role.
	 */
	if (hdev->conn_hash.le_num_slave > 0)
		return NULL;

c03ee9af4e Bluetooth: btbcm: Add 2 missing models to subver tables
Currently the bcm_uart_subver_ and bcm_usb_subver_table-s lack entries
for the BCM4324B5 and BCM20703A1 chipsets. This makes the code use just
"BCM" as prefix for the filename to pass to request-firmware, making it
harder for users to figure out which firmware they need. This especially
is problematic with the UART attached BCM4324B5 where this leads to the
filename being just "BCM.hcd".

Add the 2 missing devices to subver tables. This has been tested on:

1. A Dell XPS15 9550 where this makes btbcm.c try to load
"BCM20703A1-0a5c-6410.hcd" before it tries to load "BCM-0a5c-6410.hcd".

2. A Thinkpad 8 where this makes btbcm.c try to load
"BCM4324B5.hcd" before it tries to load "BCM.hcd"

74530a639a Bluetooth: btbcm: Try multiple Patch filenames when loading the Patch firmware
Currently the bcm_uart_subver_ and bcm_usb_subver_table-s lack entries
for various newer chipsets. This makes the code use just "BCM" as prefix
for the filename to pass to request-firmware, making it harder for users
to figure out which firmware they need. This especially a problem with
UART attached devices where this leads to the filename being "BCM.hcd".

If we add new entries to the subver-tables now, then this will change
what firmware file the kernel looks for, e.g. currently linux-firmware
contains a brcm/BCM-0bb4-0306.hcd file. If we add the info for the
BCM20703A1 to the subver table, then this will change to
brcm/BCM20703A1-0bb4-0306.hcd. This will cause the file to no longer
get loaded breaking Bluetooth for existing users, going against the
no regressions policy.

To avoid this regression make the btbcm code try multiple filenames,
first try the fullname, e.g. BCM20703A1-0bb4-0306.hcd and if that is
not found, then fallback to the name with just BCM as prefix.

This commit also adds an info message which filename was used,
this makes the output look like this for example:

[   57.387867] Bluetooth: hci0: BCM20703A1

0383f16a87 Bluetooth: btbcm: Make btbcm_setup_patchram use btbcm_finalize
On UART attached devices we do:

1. btbcm_initialize()
2. Setup UART baudrate, etc.
3. btbcm_finalize()

After our previous changes we can now also use btbcm_finalize() from
the btbcm_setup_patchram() function used on USB devices without any
functional changes. This completes unifying the USB and UART paths
as much as possible.

2fcdd562b9 Bluetooth: btbcm: Make btbcm_initialize() print local-name on re-init too
Make btbcm_initialize() get and print the device's local-name on re-init
too, this will make us also print the local-name after loading the
Patch on UART attached devices making things more consistent.

This also removes some code duplication from btbcm_setup_patchram()
and allows more code duplication removal there in a follow-up patch.

0287c5d84f Bluetooth: btbcm: Fold Patch loading + applying into btbcm_initialize()
Instead of having btbcm_initialize() fill a passed in fw_name buffer
and then have its callers use that to request the firmware + load
it into the HCI, make btbcm_initialize() do this itself the first
time it is called (its get called a second time to reset the HCI
after the firmware has been loaded).

This removes some code duplication and makes it easier for further
patches in this series to try more then 1 firmware filename.

44dd5efc97 Merge branch 'Support-programmable-pins-for-Ocelot-PTP-driver'
Yangbo Lu says:

====================
Support programmable pins for Ocelot PTP driver

The Ocelot PTP clock driver had been embedded into ocelot.c driver.
It had supported basic gettime64/settime64/adjtime/adjfine functions
by now which were used by both Ocelot switch and Felix switch.

This patch-set is to move current ptp clock code out of ocelot.c driver
maintaining as a single ocelot_ptp.c driver, and to implement 4
programmable pins with only PTP_PF_PEROUT function for now.
The PTP_PF_EXTTS function will be supported in the future, and it should
be implemented separately for Felix and Ocelot, because of different
hardware interrupt implementation in them.

Changes for v2:
	- Put PTP driver under drivers/net/ethernet/mscc/.
	- Dropped MAINTAINERS patch. Kept original maintaining.
	- Initialized PTP separately in ocelot/felix platforms.
	- Supported PPS case in programmable pin.
	- Supported disabling pin function since deadlock is fixed by Richard.
	- Returned -EBUSY if not finding pin available.
Changes for v3:
	- Re-sent.

====================
Remove vermagic header from global include folder

Changelog:
v2:
 * Changed the implementation of patch #4 to be like Masahiro wants.
I personally don't like this implementation and changing it just to move forward
this this patchset.
v1:
https://lore.kernel.org/lkml/20200415133648.1306956-1-leon@kernel.org
 * Added tags
 * Updated patch #4 with test results
 * Changed scripts/mod/modpost.c to create inclusion of vermagic.h
   from kernel folder and not from general include/linux. This is
   needed to generate *.mod.c files, while building modules.
v0:
https://lore.kernel.org/lkml/20200414155732.1236944-1-leon@kernel.org

This is followup to the failure reported by Borislav [1] and suggested
fix later on [2].

The series removes all includes of linux/vermagic.h, updates hns and
nfp to use same kernel versioning scheme (exactly like we did for
other drivers in previous cycle) and removes vermagic.h from global
include folder.

A barrier is needed here to ensure that rtl_tx sees the descriptor
changes (DescOwn set) before the updated tp->cur_tx value. Else it may
wrongly assume that the transfer has been finished already. For this
purpose smp_wmb() is sufficient.

No separate barrier is needed for ordering the descriptor changes

functions and roll back all changes on failure.

82fe299641 net/mlx5e: Set of completion request bit should not clear other adjacent bits
In notify HW (ring doorbell) flow, we set the bit to request a completion
on the TX descriptor.
When doing so, we should not unset other bits in the same byte.
Currently, this does not fix a real issue, as we still don't have a flow
where both MLX5_WQE_CTRL_CQ_UPDATE and any adjacent bit are set together.

7dfee4b1d7 net/mlx5: IPsec, Refactor SA handle creation and destruction
Currently the SA handle is created and managed as part of the common
code for different IPsec supporting HW, this handle is passed to HW
to be used on Rx to identify the SA handle that was used to
return the xfrm state to stack.

The above implementation pose a limitation on managing this handle.

Refactor by moving management of this field to the specific HW code.

Downstream patches will introduce the Connect-X support for IPsec that
will use this handle differently than current implementation.

0aab3e1b04 net/mlx5e: IPSec, Expose IPsec HW stat only for supporting HW
The current HW counters are supported only by Innova, split the ipsec
stats group into two groups, one for HW and one for SW. And expose
the HW counters to ethtool only if Innova HW is used for IPsec offload.

1dbd51d0a7 net/mlx5: Refactor mlx5_accel_esp_create_hw_context parameter list
Currently the FPGA IPsec is the only hw implementation of the IPsec
acceleration api, and so the mlx5_accel_esp_create_hw_context was
wrongly made to suit this HW api, among other in its parameter list
and some of its parameter endianness.

This implementation might not be suitable for different HW.

Refactor by group and pass all function arguments of
mlx5_accel_esp_create_hw_context in common mlx5_accel_esp_xfrm_attrs
struct field of mlx5_accel_esp_xfrm struct and correct the endianness
according to the HW being called.

The cited commit relies on include <net/geneve.h> being included
implicitly prior to include "en_accel/en_accel.h".
This mandates that all files that needs to include en_accel.h
to redantantly include net/geneve.h.

Include net/geneve.h explicitly at "en_accel/en_accel.h" to avoid
undesired constrain as above.

8c8eea07c1 net/mlx5: Use the correct IPsec capability function for FPGA ops
Currently the IPsec acceleration capability function is also used
at IPsec fpga capable device code.

This could cause a future bug as the acceleration layer is agnostic
to the device implementing its API.

Fix by using the IPsec FPGA capability function instead of acceleration
layer capability function in case of FPGA IPsec only related operations.

Downstream patches will add support for Connect-X IPsec, this can avoid
a future bug.
