1. Added support to download firmware image with mbn type for wcn6750
as it supports mbn type image.
2. If mbn type image is not present then check for tlv type image.
3. Added debug logs for mbn type image.

Added regulators,GPIOs and changes required to power on/off wcn6750.
Added support for firmware download for wcn6750.
Changes done in detail:
1. Added regulators and corresponding current values.
2. Added sw_ctrl GPIO pin which is output from BT SoC and indicates
status of clock supply to BT SoC.
3. Added inline function to check if the SoC type is wcn6750.
4. Modified the function qca_wcn3990_init() to support wcn6750 and
renamed it to qca_regulator_init().

During command status or command complete event, the controller may set
ncmd=0 indicating that it is not accepting any more commands. In such a
case, host holds off sending any more commands to the controller. If the
controller doesn't recover from such condition, host will wait forever,
until the user decides that the Bluetooth is broken and may power cycles
the Bluetooth.
This patch triggers the hardware error to reset the controller and
driver when it gets into such state as there is no other wat out.

In qca_power_shutdown() qcadev local variable is
initialized by hu->serdev.dev private data, but
hu->serdev can be NULL and there is a check for it.
Since, qcadev is not used before
if (!hu->serdev)
return;
we can move its initialization after this "if" to
prevent GPF.

When cmtp_attach_device fails, cmtp_add_connection returns the error value
which leads to the caller to doing fput through sockfd_put. But
cmtp_session kthread, which is stopped in this path will also call fput,
leading to a potential refcount underflow or a use-after-free.
Add a refcount before we signal the kthread to stop. The kthread will try
to grab the cmtp_session_sem mutex before doing the fput, which is held
when get_file is called, so there should be no races there.

- .activate() is called next, when the clients calls

Check for the IRQ MUX conflict during the first stage (alloc instead of
activate). This avoids to provide the client with an IRQ that can't be

The purpose of the device-managed functions is to bind the life-time of an
object to that of a parent device object.
This is not the case for the 'vdd-cpu' regulator in this driver. A
reference is obtained via devm_regulator_get() and immediately released
with devm_regulator_put().
In this case, the usage of devm_ functions is slightly excessive, as the
un-managed versions of these functions is a little cleaner (and slightly
more economical in terms of allocation).
This change converts the devm_regulator_{get,put}() to
regulator_{get,put}() in the get_alignment_from_regulator() function of
this driver.

(due to cache being full) within the last second. If so writeback is

The newly implemented fwnode_mdbiobus_register turned out to be
problematic - in case the fwnode_/of_/acpi_mdio are built as
modules, a dependency cycle can be observed during the depmod phase of
modules_install, eg.:
depmod: ERROR: Cycle detected: fwnode_mdio -> of_mdio -> fwnode_mdio
depmod: ERROR: Found 2 modules in dependency cycles!
OR:
depmod: ERROR: Cycle detected: acpi_mdio -> fwnode_mdio -> acpi_mdio
depmod: ERROR: Found 2 modules in dependency cycles!
A possible solution could be to rework fwnode_mdiobus_register,
so that to merge the contents of acpi_mdiobus_register and
of_mdiobus_register. However feasible, such change would
be very intrusive and affect huge amount of the of_mdiobus_register
users.
Since there are currently 2 users of ACPI and MDIO
(xgmac_mdio and mvmdio), withdraw the fwnode_mdbiobus_register
and roll back to a simple 'if' condition in affected drivers.

The E810 device supports programmable pins for enabling both input and
output events related to the PTP hardware clock. This includes both
output signals with programmable period, as well as timestamping of
events on input pins.
Add support for enabling these using the CONFIG_PTP_1588_CLOCK
interface.
This allows programming the software defined pins to take advantage of
the hardware clock features.

This patch adds build and driver logic for the "mlxbf_gige"
Ethernet driver from Mellanox Technologies. The second
generation BlueField SoC from Mellanox supports an
out-of-band GigaBit Ethernet management port to the Arm
subsystem. This driver supports TCP/IP network connectivity
for that port, and provides back-end routines to handle
basic ethtool requests.
The driver interfaces to the Gigabit Ethernet block of
BlueField SoC via MMIO accesses to registers, which contain
control information or pointers describing transmit and
receive resources. There is a single transmit queue, and
the port supports transmit ring sizes of 4 to 256 entries.
There is a single receive queue, and the port supports
receive ring sizes of 32 to 32K entries. The transmit and
receive rings are allocated from DMA coherent memory. There
is a 16-bit producer and consumer index per ring to denote
software ownership and hardware ownership, respectively.
The main driver logic such as probe(), remove(), and netdev
ops are in "mlxbf_gige_main.c". Logic in "mlxbf_gige_rx.c"
and "mlxbf_gige_tx.c" handles the packet processing for
receive and transmit respectively.
The logic in "mlxbf_gige_ethtool.c" supports the handling
of some basic ethtool requests: get driver info, get ring
parameters, get registers, and get statistics.
The logic in "mlxbf_gige_mdio.c" is the driver controlling
the Mellanox BlueField hardware that interacts with a PHY
device via MDIO/MDC pins. This driver does the following:
- At driver probe time, it configures several BlueField MDIO
parameters such as sample rate, full drive, voltage and MDC
- It defines functions to read and write MDIO registers and
registers the MDIO bus.
- It defines the phy interrupt handler reporting a
link up/down status change
- This driver's probe is invoked from the main driver logic
while the phy interrupt handler is registered in ndo_open.
Driver limitations
- Only supports 1Gbps speed
- Only supports GMII protocol
- Supports maximum packet size of 2KB
- Does not support scatter-gather buffering
Testing
- Successful build of kernel for ARM64, ARM32, X86_64
- Tested ARM64 build on FastModels & Palladium
- Tested ARM64 build on several Mellanox boards that are built with
the BlueField-2 SoC. The testing includes coverage in the areas
of networking (e.g. ping, iperf, ifconfig, route), file transfers
(e.g. SCP), and various ethtool options relevant to this driver.

The goal is to keep the mark during a bpf_redirect(), like it is done for
legacy encapsulation / decapsulation, when there is no x-netns.
This was initially done in commit 213dd74aee76 ("skbuff: Do not scrub skb
mark within the same name space").
When the call to skb_scrub_packet() was added in dev_forward_skb() (commit
8b27f27797ca ("skb: allow skb_scrub_packet() to be used by tunnels")), the
second argument (xnet) was set to true to force a call to skb_orphan(). At
this time, the mark was always cleanned up by skb_scrub_packet(), whatever
xnet value was.
This call to skb_orphan() was removed later in commit
9c4c325252c5 ("skbuff: preserve sock reference when scrubbing the skb.").
But this 'true' stayed here without any real reason.
Let's correctly set xnet in ____dev_forward_skb(), this function has access
to the previous interface and to the new interface.
