VSI supported nodes are calculated in order to add the VSI parent or
intermediate nodes to the scheduler tree. If one of the node in below
layers (from VSI layer) has space to add the new VSI or intermediate node
above that layer then it's not required to continue the calculation further
for below layers.

Currently ICE_MAX_MTU subtracts only ETH_HLEN from max frame size and
adds ETH_FCS_LEN and VLAN_HLEN, which is not what was intended.
The ETH_HLEN + ETH_FCS_LEN + VLAN_HLEN expression should be surrounded
with parentheses.
Wrap mentioned expression and take into account VLAN double tagging.

Commit 87b0984ebfab ("net: Add extack argument to ndo_fdb_add()") in
net-next added an extended parameter to the .ndo_fdb_add op and changed
ice_fdb_add() accordingly. Update the function header and add the
__always_unused attribute to the new parameter to avoid -Wunused-parameter

I have encountered an interrupt storm during the eMMC chip probing (and
the chip finally didn't get detected). It turned out that U-Boot left
the DMAC interrupts enabled while the Linux driver didn't use those.
The SDHI driver's interrupt handler somehow assumes that, even if an
SDIO interrupt didn't happen, it should return IRQ_HANDLED. I think
that if none of the enabled interrupts happened and got handled, we
should return IRQ_NONE -- that way the kernel IRQ code recoginizes
a spurious interrupt and masks it off pretty quickly...

The only user of mmc_align_data_size() is sdio_align_size(), which is
called from SDIO func drivers to let them distinguish, how to optimally
allocate data buffers.
Let's move mmc_align_data_size() close to the SDIO code as to make it
static, rename it to _sdio_align_size() and simplify its definition, all
with the purpose of clarifying that this is SDIO specific.

ME FW contributes a vital role in HDCP2.2 authentication.
HDCP2.2 driver needs to communicate to ME FW for each step of the
HDCP2.2 authentication.
ME FW prepare and HDCP2.2 authentication parameters and encrypt them
as per spec. With such parameter Driver prepares HDCP2.2 auth messages
and communicate with HDCP2.2 sink.
Similarly HDCP2.2 sink's response is shared with ME FW for decrypt and
verification.
Once All the steps of HDCP2.2 authentications are complete on driver's
request ME FW will configure the port as authenticated and supply the
HDCP keys to the Gen HW for encryption.
Only after this stage HDCP2.2 driver can start the HDCP2.2 encryption
for a port.
ME FW is interfaced to kernel through MEI Bus Driver. To obtain the
HDCP2.2 services from the ME FW through MEI Bus driver MEI Client
Driver is developed.

When using the mmc_spi driver with a card-detect pin, I noticed that the
card was not detected immediately after probe, but only after it was
unplugged and plugged back in (and the CD IRQ fired).
The call tree looks something like this:
mmc_spi_probe
mmc_add_host
mmc_start_host
_mmc_detect_change
mmc_schedule_delayed_work(&host->detect, 0)
mmc_rescan
host->bus_ops->detect(host)
mmc_detect
_mmc_detect_card_removed
host->ops->get_cd(host)
mmc_gpio_get_cd -> -ENOSYS (ctx->cd_gpio not set)
mmc_gpiod_request_cd
ctx->cd_gpio = desc
To fix this issue, call mmc_detect_change after the card-detect GPIO/IRQ
is registered.

MMC OF parsing functions, which parses various host DT properties, should
stay close to each other. Therefore, let's move mmc_of_parse_voltage()
close to mmc_of_parse() into host.c.
Additionally, there is no reason to build the code only when CONFIG_OF is
set, as there should be stub functions for the OF helpers that is being
used, so let's drop this condition as well.

The mmc regulator helper functions, are placed in the extensive core.c

avoiding too many lines of code per file, let's move these helpers to a new

Moreover, this within this context it makes sense to also drop the export

include/linux/device.h:709:15: note: expected 'struct resource *'
but argument is of type 'const struct resource *'
void __iomem *devm_ioremap_resource(struct device *dev,struct resource *res);
^~~~~~~~~~~~~~~~~~~~~
Let's just remove "const" for now.
It is possible that devm_ioremap_resource() should rather
be constified so we can pass const resources as arguments.
But right now I just want to get rid of this build warning.

SCC is used for SDR104/HS200/HS400. We need to change SCC_DT2FF
according to the mode. If it is inappropriate, CRC error tends to occur.
This adds variable "tap_hs400" for HS400 mode and configures SCC_DT2FF
as needed.

On i.MX8MQ platform, clock driver uses platform driver
model and it is probed after GPIO driver, so when GPIO
driver fails to get clock, it should check the error type
to decide whether to return defer probe or just ignore
the clock operation.

The current approach with sending a CMD12 (STOP_TRANSMISSION) to complete a
data transfer request, either because of using the open-ended transmission
type or because of receiving an error during a pre-defined data transfer,
isn't sufficient for the STM32 sdmmc variant. More precisely, this variant
needs to clear the DPSM ("Data Path State Machine") by sending a CMD12, for
all failing ADTC commands.
Support this, by adding a struct mmc_command inside the struct mmci_host
and initialize it to a CMD12 during ->probe(). Let's also add checks for
the new conditions, to enable mmci_data_irq() and mmci_cmd_irq() to
postpone the calls to mmci_request_end(), but instead send the CMD12.

Even though SDHCI controllers may have a dedicated WP pin that can be
queried using the SDHCI_PRESENT_STATE register, some platforms may
chose to use a separate regular GPIO to route the WP signal. Such a
GPIO is typically represented using the wp-gpios property in the
Device Tree.
Unfortunately, the current sdhci_check_ro() function does not make use
of such GPIO when available: it either uses a host controller specific
->get_ro() operation, or uses the SDHCI_PRESENT_STATE. Several host
controller specific ->get_ro() functions are implemented just to check
a WP GPIO state.
Instead of pushing this to more controller-specific implementations,
let's handle this in the core SDHCI code, just like it is already done
for the CD GPIO in sdhci_get_cd().
The below patch simply changes sdhci_check_ro() to use the value of
the WP GPIO if available.

The argument "override_active_level" made it possible to
enforce a specific polarity on the write-protect
GPIO line. All callers in the kernel pass "false" to this
call after I have converted all drivers to use GPIO machine
descriptors, so remove the argument and clean out this.
This kind of polarity inversion should be handled by the
GPIO descriptor inside the GPIO library if needed.
This rids us of one instance of the kludgy calls into
the gpiod_get_raw_value() API.

The BCM2835 MMC host driver uses a pointer to get from the private
bcm2835_host structure to the generic mmc_host structure. However the
latter is always immediately preceding the former in memory, so compute
its address with a subtraction (which is cheaper than a dereference) and
drop the superfluous pointer.
No functional change intended.
