Now that the core NAND subsystem has support for on-die ECC, this commit
brings the necessary code to support on-die ECC on Micron NANDs.
In micron_nand_init(), we detect if the Micron NAND chip supports on-die
ECC mode, by checking a number of conditions:
- It must be an ONFI NAND
- It must be a SLC NAND
- Enabling *and* disabling on-die ECC must work
- The on-die ECC must be correcting 4 bits per 512 bytes of data. Some
Micron NAND chips have an on-die ECC able to correct 8 bits per 512
bytes of data, but they work slightly differently and therefore we
don't support them in this patch.
Then, if the on-die ECC cannot be disabled (some Micron NAND have on-die
ECC forcefully enabled), we bail out, as we don't support such
NANDs. Indeed, the implementation of raw_read()/raw_write() make the
assumption that on-die ECC can be disabled. Support for Micron NANDs
with on-die ECC forcefully enabled can easily be added, but in the
absence of such HW for testing, we preferred to simply bail out.
If the on-die ECC is supported, and requested in the Device Tree, then
it is indeed enabled, by using custom implementations of the
->read_page(), ->read_page_raw(), ->write_page() and ->write_page_raw()
operation to properly handle the on-die ECC.
In the non-raw functions, we need to enable the internal ECC engine
before issuing the NAND_CMD_READ0 or NAND_CMD_SEQIN commands, which is
why we set the NAND_ECC_CUSTOM_PAGE_ACCESS option at initialization
time (it asks the NAND core to let the NAND driver issue those
commands).

The KSZ9477 is a fully integrated layer 2, managed, 7 ports GigE switch
with numerous advanced features. 5 ports incorporate 10/100/1000 Mbps PHYs.
The other 2 ports have interfaces that can be configured as SGMII, RGMII, MII
or RMII. Either of these may connect directly to a host processor or
to an external PHY. The SGMII port may interface to a fiber optic transceiver.
This driver currently supports vlan, fdb, mdb & mirror dsa switch operations.

A lot of drivers are providing their own ->cmdfunc(), and most of the
time this implementation does not support all possible NAND operations.
But since ->cmdfunc() cannot return an error code, the core has no way
to know that the operation it requested is not supported.
This is a problem we cannot address for all kind of operations with the
current design, but we can prevent these silent failures for the
GET/SET FEATURES operation by overloading the default
->onfi_{set,get}_features() methods with one returning -ENOTSUPP.

Pull pin control fixes from Linus Walleij:
"Here is an overdue pull request for pin control fixes, the most
prominent feature is to make Intel Chromebooks (and I suspect any
other Cherryview-based Intel thing) happy again, which we really want
to see.
There is a patch hitting drivers/firmware/* that I was uncertain to
who actually manages, but I got Andy Shevchenko's and Dmitry Torokov's
review tags on it and I trust them both 100% to do the right thing for
Intel platform drivers.
Summary:
- Make a few Intel Chromebooks with Cherryview DMI firmware work
smoothly.
- A fix for some bogus allocations in the generic group management
code.
- Some GPIO descriptor lookup table stubs. Merged through the pin
control tree for administrative reasons.
- Revert the "bi-directional" and "output-enable" generic properties:
we need more discussions around this. It seems other SoCs are using
input/output gate enablement and these terms are not correct.
- Fix mux and drive strength atomically in the MXS driver.
- Fix the SPDIF function on sunxi A83T.
- OF table terminators and other small fixes"

The CPU cooling driver uses the cpufreq policy, to get clip_cpus, the
frequency table, etc. Most of the callers of CPU cooling driver's
registration routines have the cpufreq policy with them, but they only
pass the policy->related_cpus cpumask. The __cpufreq_cooling_register()
routine then gets the policy by itself and uses it.
It would be much better if the callers can pass the policy instead
directly. This also fixes a basic design flaw, where the policy can be
freed while the CPU cooling driver is still active.

Some Ethernet drivers will attach/connect to a PHY device before calling
register_netdevice() which is responsible for calling netdev_register_kobject()
which would do the network device's kobject initialization. In such a case,
sysfs_create_link() would return -ENOENT because the network device's kobject
is not ready yet, and we would fail to connect to the PHY device.
In order to keep things simple and symetrical, we just take the success path as
indicative of the ability to access the network device's kobject, and create
the second link if that's the case.

When netdev events happen, a rtnetlink_event() handler will send
messages for every event in it's white list. These messages contain
current information about a particular device, but they do not include
the iformation about which event just happened. So, it is impossible
to tell what just happend for these events.
This patch adds a new extension to RTM_NEWLINK message called IFLA_EVENT
that would have an encoding of event that triggered this
message. This would allow the the message consumer to easily determine
if it needs to perform certain actions.

During enslavement to a bridge, after the CHANGEUPPER is sent, the
multicast enabled state of the bridge isn't propagated down to the
offloading driver unless it's changed.
This patch allows such drivers to query the multicast enabled state from
the bridge, so that they'll be able to correctly configure their flood
tables during port enslavement.
In case multicast is disabled, unregistered multicast packets can be
treated as broadcast and be flooded through all the bridge ports.

the bridge's VLAN filtering state.
Currently, upon enslavement to a bridge master, the offloading driver
will only learn about the bridge's VLAN filtering state after the bridge
device was already linked with its slave.
Being able to query the bridge's VLAN filtering state allows such
drivers to forbid enslavement in case resource couldn't be allocated for
a VLAN-aware bridge and also choose the correct initialization routine
for the enslaved port, which is dependent on the bridge type.

Pull block fixes from Jens Axboe:
"A collection of fixes that should go into this series. This contains:
- A set of NVMe fixes, pulled from Christoph. This includes a set of
fixes for the fiber channel bits from James Smart, rdma queue depth
fix from Marta, controller removal fixes from Ming, and some more
APST quirk updates from Andy.
- A blk-mq debugfs fix from Bart, fixing a problem with the
untangling of the sysfs and debugfs blk-mq bits that was added in
this series.
- Error code fix in add_partition() from Dan.
- A small series of fixes for the new blk-throttle code from Shaohua"

We need to return an error for any call that asks for MSI / MSI-X
vectors only, so that non-trivial fallback logic can work properly.
Also valid dev->irq and use the "correct" errno value based on feedback

Add slave mode support to the MSIOF driver, in both PIO and DMA mode.
For now this only supports the transmission of messages with a size
that is known in advance.

Add support for registering SPI slave controllers using the existing SPI
master framework:
- SPI slave controllers must use spi_alloc_slave() instead of
spi_alloc_master(), and should provide an additional callback
"slave_abort" to abort an ongoing SPI transfer request,
- SPI slave controllers are added to a new "spi_slave" device class,
- SPI slave handlers can be bound to the SPI slave device represented
by an SPI slave controller using a DT child node named "slave",
- Alternatively, (un)binding an SPI slave handler to the SPI slave
device represented by an SPI slave controller can be done by
(un)registering the slave device through a sysfs virtual file named
"slave".
From the point of view of an SPI slave protocol handler, an SPI slave
controller looks almost like an ordinary SPI master controller. The only
exception is that a transfer request will block on the remote SPI
master, and may be cancelled using spi_slave_abort().
