Currently PF and VF use two sets of command code for modules to interact
with firmware. These codes values are same espect the macro names. It is
redundent to keep two sets of command code for same functions between PF
and VF.
So this patch firstly creates a unified command code for PF and VF module.
We keep the macro name same with the PF command code name to avoid too many
meaningless modifications. Secondly the new common command codes are used
to replace the old ones in VF and deletes the old ones.

Currently, there are two different sets of special command codes in PF and
VF cmdq modules, this is because VF driver only uses small part of all the
command codes. In other words, these not used command codes in VF are also
sepcial command codes theoretically.

is_pf of hclge_comm_send. All the related functions are refactored
according to the new hclge_comm_send function prototype.

Currently PF stores its rss parameters in vport structure. VF stores rss
configurations in hclgevf_rss_cfg structure. Actually hns3 rss parameters
are same beween PF and VF. The two set of rss parameters are redundent and
may add extra bugfix work.
So this patch creates new common rss parameter struct(hclge_comm_rss_cfg)
to unify PF and VF rss configurations.
These new structures will be used to unify rss configurations in PF and VF

Extend lan966x driver with mdb support by implementing the switchdev
calls: SWITCHDEV_OBJ_ID_PORT_MDB and SWITCHDEV_OBJ_ID_HOST_MDB.
It is allowed to add both ipv4/ipv6 entries and l2 entries. To add
ipv4/ipv6 entries is not required to use the PGID table while for l2
entries it is required. The PGID table is much smaller than MAC table

Currently, the CAN netlink interface provides no easy ways to check
the capabilities of a given controller. The only method from the
command line is to try each CAN_CTRLMODE_* individually to check
whether the netlink interface returns an -EOPNOTSUPP error or not
(alternatively, one may find it easier to directly check the source
code of the driver instead...)
This patch introduces a method for the user to check both the
supported and the static capabilities. The proposed method introduces
a new IFLA nest: IFLA_CAN_CTRLMODE_EXT which extends the current
IFLA_CAN_CTRLMODE. This is done to guaranty a full forward and
backward compatibility between the kernel and the user land
applications.
The IFLA_CAN_CTRLMODE_EXT nest contains one single entry:
IFLA_CAN_CTRLMODE_SUPPORTED. Because this entry is only used in one
direction: kernel to userland, no new struct nla_policy are
introduced.
Below table explains how IFLA_CAN_CTRLMODE_SUPPORTED (hereafter:
"supported") and can_ctrlmode::flags (hereafter: "flags") allow us to
identify both the supported and the static capabilities, when masked
with any of the CAN_CTRLMODE_* bit flags:
supported & flags & Controller capabilities
CAN_CTRLMODE_* CAN_CTRLMODE_*
-----------------------------------------------------------------------
false false Feature not supported (always disabled)
false true Static feature (always enabled)

Previous patch removed can_priv::ctrlmode_static to replace it with
can_get_static_ctrlmode().
A condition sine qua non for this to work is that the controller
static modes should never be set in can_priv::ctrlmode_supported
(c.f. the comment on can_priv::ctrlmode_supported which states that it
is for "options that can be *modified* by netlink"). Also, this
condition is already correctly fulfilled by all existing drivers
which rely on the ctrlmode_static feature.
Nonetheless, we added an extra safeguard in can_set_static_ctrlmode()
to return an error value and to warn the developer who would be
adventurous enough to set to static a given feature that is already
set to supported.
The drivers which rely on the static controller mode are then updated
to check the return value of can_set_static_ctrlmode().

The statically enabled features of a CAN controller can be retrieved
using below formula:
| u32 ctrlmode_static = priv->ctrlmode & ~priv->ctrlmode_supported;
As such, there is no need to store this information. This patch remove
the field ctrlmode_static of struct can_priv and provides, in
replacement, the inline function can_get_static_ctrlmode() which
returns the same value.

The actual payload length of the CAN Remote Transmission Request (RTR)
frames is always 0, i.e. no payload is transmitted on the wire.
However, those RTR frames still use the DLC to indicate the length of
the requested frame.
As such, net_device_stats::tx_bytes should not be increased when
sending RTR frames.
The function can_get_echo_skb() already returns the correct length,
even for RTR frames (c.f. [1]). However, for historical reasons, the
drivers do not use can_get_echo_skb()'s return value and instead, most
of them store a temporary length (or dlc) in some local structure or
array. Using the return value of can_get_echo_skb() solves the
issue. After doing this, such length/dlc fields become unused and so
this patch does the adequate cleaning when needed.
This patch fixes all the CAN drivers.
Finally, can_get_echo_skb() is decorated with the __must_check
attribute in order to force future drivers to correctly use its return
value (else the compiler would emit a warning).

However, those RTR frames still use the DLC to indicate the length of

For this reason, it is incorrect to copy the payload of RTR frames
(the payload buffer would only contain garbage data). This patch
encapsulates the payload copy in a check toward the RTR flag.

The CAN error message frames (i.e. error skb) are an interface
specific to socket CAN. The payload of the CAN error message frames
does not correspond to any actual data sent on the wire. Only an error
flag and a delimiter are transmitted when an error occurs (c.f. ISO
11898-1 section 10.4.4.2 "Error flag").
For this reason, it makes no sense to increment the tx_packets and
tx_bytes fields of struct net_device_stats when sending an error
message frame because no actual payload will be transmitted on the
wire.
N.B. Sending error message frames is a very specific feature which, at
the moment, is only supported by the Kvaser Hydra hardware. Please
refer to [1] for more details on the topic.

The field dev_port of struct net_device indicates the port number of a
network device [1]. This patch populates this field.
This field can be helpful to distinguish between the two network
interfaces of a dual channel device (i.e. ES581.4 or ES582.1). Indeed,
at the moment, all the network interfaces of a same device share the
same static udev attributes c.f. output of:
| udevadm info --attribute-walk /sys/class/net/canX
The dev_port attribute can then be used to write some udev rules to,
for example, assign a permanent name to each network interface based
on the serial/dev_port pair (which is convenient when you have a test
bench with several CAN devices connected simultaneously and wish to
keep consistent interface names upon reboot).

Add support for instantiating platform-devs, note this also makes some
small changes to the i2c_client instantiating code to make the 2 flows
identical.
Specifically for the pdevs flow pdev_count must only be set after
allocating the pdevs array, to avoid a NULL ptr deref in
x86_android_tablet_cleanup() and the i2c_clients flow is updated
to work the same way.

The Crystal Cove PMIC has a pin which can be used to connect the IRQ of
an external charger IC. On some boards this is used so we need a way to
look this up.
Note that the Intel PMICs have 2 levels of interrupts and thus
2 levels of IRQ domains all tied to a single fwnode.
Level 1 is the irqchip which demultiplexes the actual PMIC interrupt into
interrupts for the various MFD cells. Level 2 are the irqchips used in the
cell drivers which themselves export IRQs, such as the crystal_cove_gpio
driver, which de-multiplexes the level 2 interrupts for the GPIOs into
individual per GPIO IRQs.
The crystal_cove_charger driver registers an irqchip with a single IRQ for
the charger driver to consume. Note the MFD cell IRQ cannot be consumed
directly because the level 2 interrupts must be explicitly acked.
To allow finding the right IRQ domain when looking up the IRQ for
the charger, the crystal_cove_charger driver sets a DOMAIN_BUS_WIRED token
on its IRQ domain.
Add support for looking up the IRQ from the crystal_cove_charger driver.

probe() function
The x86-android-tablets code all runs from module_init, so returning
-EPROBE_DEFER is not appropriate. Instead log an error and bail.
This path should never get hit since PINCTRL_BAYTRAIL is a bool.

The Glavey TM800A550L tablet is a tablet which ships with Android as
factory OS. As such it has the typical broken DSDT which x86 Android
tablets tend to have.
Specifically the touchscreen ACPI device node is missing the IRQ for
the touchscreen. So far users were expected to fix this with a DSDT
overlay, but support for the TM800A550L has been added to the new
x86-android-modules kernel-module and that will now automatically
instantiate a proper i2c-client with the IRQ set for the touchscreen,
including the necessary device-properties for the firmware loading.
This means that the touchscreen_dmi entry for the TM800A550L is
no longer necessary (and it no longer matches either since the
touchscreen is no longer enumerated through ACPI), remove it.

(CWI529) tablet
The firmware distributed as part of the Windows and Android drivers uses
significantly different min and max values for the x- and y-axis,
compared to the EFI's embedded touchscreen firmware.
The difference is large enough that e.g. typing on an onscreen keyboard
results in the wrong "keys" getting pressed.
Adjust the values to match those of the firmware distributed with the
Windows and Android drivers (which is necessary for pen support) and
put the EFI-fw version's min/max values in the new "silead,efi-fw-min-max"
property. The silead driver will use these when it is using the
EFI embedded firmware, so as to not regress functionality in that case.

Driver for the external-charger IRQ pass-through function of the
Intel Bay Trail Crystal Cove PMIC.
Note this is NOT a power_supply class driver, it just deals with IRQ
pass-through, this requires this separate driver because the PMIC's
level 2 interrupt for this must be explicitly acked.
This new driver gets enabled by the existing X86_ANDROID_TABLETS Kconfig
option because the x86-android-tablets module is the only consumer of the
exported external-charger IRQ.

GPIO library does copy the of_node from the parent device of the GPIO
chip, there is no need to repeat this in the individual drivers.
Remove assignment here.
For the details one may look into the of_gpio_dev_init()
implementation.
