Fixed problem with setting spi mode 0 or 1 after setting mode 2 or 3
SPI_MODE_0 and SPI_MODE_1 requires clock low when inactive. SPI_MODE_2
and SPI_MODE_3 requires clk high when inactive.
Currently driver can just set bits in fields SCLK_PHA (SPI Clock/Data
Phase Control), SCLK_POL (SPI Clock Polarity Control),
SCLK_CTL (controls the inactive state of SCLK) ans SS_POL (SPI SS
Polarity Select) of ECSPIx_CONFIGREG register.
This patch allows driver to clear corresponding bits in these fields.

The keyboard driver for GPIO buttons(gpio-keys) checks for one of the
two boolean properties to enable gpio buttons as wakeup source:
1. "wakeup-source" or
2. the legacy "gpio-key,wakeup"
However juno, ste-snowball and emev2-kzm9d dts file have a undetected
"wakeup" property to indictate the wakeup source.
This patch fixes it by making use of "wakeup-source" property.

Add AC'97 support to fsl-asoc-card using generic
ASoC AC'97 CODEC.
The SSI controller will silently enable any TX
AC'97 slots that have their bits set in SLOTREQ
received from CODEC and then will redirect some
of playback samples there.
That's why it is important to make sure that
any of CODEC playback slots that can pull samples
are set to slots 3/4 (standard PCM playback slots).
Currently, this applies to S/PDIF slots as they
were seen to pull samples sometimes even with
S/PDIF output being disabled.

Now, in ->symlink of f2fs, we kept the fixed invoking order between

But we didn't fix to release meta info which was done before page_symlink

Currently there is no clear definition of what FSYNC polarity is.
Different drivers use its own definition of what is "normal" and what is
"inverted" fsync. This leads to compatibility problems between drivers.
For example TegraX1 driver assumes that DSP-A format with frames
starting at rising FSYNC edge has "inverted" polarity,
while RT5677 assumes it is "normal" polarity.
Explicitly specify meaning of BCLK/FSYNC polarity to avoid future
compatibility problems.

Move all register definitions and structs into the driver. This allows
us dropping the platform_data struct and drop any arch specific
includes. Make use of different device names to identify the version of
the block we have.
Since we now have full control over the message width, we can drop the
size check, which was broken anyway, since it never set ret to any error
code.
Also since we now have no arch depedendent resources, we can now allow
compiling it for any arch, hidden behind COMPILE_TEST.

The driver depends on MFD_STW481X but there isn't a build dependency so
it's a good idea to allow the driver to always be built when the
COMPILE_TEST option is enabled.
That way, the driver can be built with a config generated by make
allyesconfig and check if a patch would break the build.

While there is nothing wrong with the transfer_ack_begin and
transfer_ack_end callbacks per-se, the last documented user was part of the
alsa-driver 0.5.12a package, which was released 14 years ago and even
predates the upstream integration of the ALSA core and has subsequently
been superseded by newer alsa-driver releases.
This seems to indicate that there is no need for having these callbacks and
they are just cruft that can be removed.

2) Fix some header checks in _decode_session6.
We skip the header informations if the data pointer points
already behind the header in question for some protocols.
This is because we call pskb_may_pull with a negative value
converted to unsigened int from pskb_may_pull in this case.
Skipping the header informations can lead to incorrect policy

net: dsa: implement port_fdb_dump in drivers
Not all switch chips provide a Get Next kind of operation to dump FDB entries.
It is preferred to let the driver handle the dump operation the way it works
best for the chip. Thus, drop port_fdb_getnext and implement the port_fdb_dump
operation in DSA, which pushes the switchdev FDB dump callback down to the
drivers. mv88e6xxx is the only driver affected and is updated accordingly.
v3 -> v4: fix rejects on latest net-next
v2 -> v3: opencode switchdev_obj_dump_cb_t to avoid multiple typedef;
use ether_addr_copy in fdb_dump

There is no need to write the MAC address before every Get Next
operation, since ATU MAC registers are not cleared between calls.

Since the "Switch driver to use transfer_one" change, the cs_change
behavior has changed and a channel chip select can still be
asserted when changing channel from a previous last transfer in a
message having the cs_change attribute.
Since there is no sense having multiple chip select being asserted at the
same time, disable all the remaining forced chip selects in a the
prepare_message called right before a spi_transfer_one_message call.
It ignores the current channel configuration in order to keep the
possibility to leave the chip select asserted between messages.
It fixes this bug on a DM8168 SoC ES2.1 Soc and an OMAP4 ES2.1 SoC.
It was hanging all the other channels transfers when a CHCONF_FORCE
is present on the wrong channel.
