Exynos850 has the same version of USI SPI (v2.1) as GS101.
Drop the fifo_lvl_mask and rx_lvl_offset and switch to the new port
config data.
Backward compatibility with DT is not broken because when alises are
set:
- the SPI core will set the bus number according to the alias ID
- the FIFO depth is always the same size for exynos850 (64 bytes) no
matter the alias ID number.
Advantages of the change:
- drop dependency on the OF alias ID.
- FIFO depth is inferred from the compatible. Exynos850 integrates 3 SPI
IPs, all with 64 bytes FIFO depths.
- use full mask for SPI_STATUS.{RX, TX}_FIFO_LVL fields. Using partial
masks is misleading and can hide problems of the driver logic.

S3C64XX_SPI_ST_TX_FIFO_RDY_V2 was defined based on the USI's

There are SoCs that use the same FIFO depth for all the instances of the
SPI IP. See the fifo_lvl_mask defined for gs101 for example:
.fifo_lvl_mask = { 0x7f, 0x7f, 0x7f, 0x7f, 0x7f, 0x7f, 0x7f, 0x7f,
0x7f, 0x7f, 0x7f, 0x7f, 0x7f, 0x7f, 0x7f, 0x7f},
Instead of specifying the FIFO depth with the same value for all 16
nodes in this case, allow such SoCs to infer the FIFO depth from the
compatible. There are other SoCs than can benefit of this, see:
{gs101, fsd, exynos850, s3c641, s3c2443}_spi_port_config.
The FIFO depth inferred from the compatible has a higher precedence than
the one that might be specified via device tree, the driver shall know
better.

of the SPI IP. See the fifo_lvl_mask defined for exynos4_spi_port_config
for example:

The first instance of the IP is configured with 256 bytes FIFOs, whereas

The driver is wrong because is using partial register field masks for the
SPI_STATUS.{RX, TX}_FIFO_LVL register fields.
We see s3c64xx_spi_port_config.fifo_lvl_mask with different values for
different instances of the same IP. Take s5pv210_spi_port_config for
example, it defines:
.fifo_lvl_mask = { 0x1ff, 0x7F },
fifo_lvl_mask is used to determine the FIFO depth of the instance of the
IP. In this case, the integrator uses a 256 bytes FIFO for the first SPI
instance of the IP, and a 64 bytes FIFO for the second instance. While
the first mask reflects the SPI_STATUS.{RX, TX}_FIFO_LVL register
fields, the second one is two bits short. Using partial field masks is
misleading and can hide problems of the driver's logic.
Allow platforms to specify the full FIFO mask, regardless of the FIFO
depth.
Introduce {rx, tx}_fifomask to represent the SPI_STATUS.{RX, TX}_FIFO_LVL
register fields. It's a shifted mask defining the field's length and
position. We'll be able to deprecate the use of @rx_lvl_offset, as the
shift value can be determined from the mask. The existing compatibles
shall start using {rx, tx}_fifomask so that they use the full field mask
and to avoid shifting the mask to position, and then shifting it back to
zero in the {TX, RX}_FIFO_LVL macros.
@rx_lvl_offset will be deprecated in a further patch, after we have the
infrastructure to deprecate @fifo_lvl_mask as well.
No functional change intended.

There are SPI IPs that can be configured by the integrator with a
specific FIFO depth depending on the system's capabilities. For example,
the samsung USI SPI IP can be configured by the integrator with a TX/RX
FIFO from 8 byte to 256 bytes.
Introduce the ``fifo-depth`` property for such instances of IPs where the
same FIFO depth is used for both RX and TX. Introduce ``rx-fifo-depth``
and ``tx-fifo-depth`` properties for cases where the RX FIFO depth is
different from the TX FIFO depth.
Make the dedicated RX/TX properties dependent on each other and mutual
exclusive with the other.

According to x86 spec ([1] and [2]), MWAIT hint_address[7:4] plus 1 is
the corresponding C-state, and 0xF means C0.
ACPI C-state table usually only contains C1+, but nothing prevents ACPI
firmware from presenting a C-state (maybe C1+) but using MWAIT address C0
(i.e., 0xF in ACPI FFH MWAIT hint address). And if this is the case, Linux
erroneously treat this cstate as C16, while actually this should be valid
C0 instead of C16, as per the specifications.
Since ACPI firmware is out of Linux kernel scope, fix the kernel handling
of 0xF ->(to) C0 in this situation. This is found when a tweaked ACPI
C-state table is presented by Qemu to VM.
Also modify the intel_idle case for code consistency.

The DSC HW state of DP connectors is read out during driver loading and
system resume in intel_modeset_update_connector_atomic_state(). This
function is called for all connectors though and so the state of DSI
connectors will also get updated incorrectly, triggering a WARN there
wrt. the DSC decompression AUX device.
Fix the above by moving the DSC state readout to a new DP connector
specific sync_state() hook. This is anyway the logical place to update
the connector object's state vs. the connector's atomic state.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

Add two erratas for lan8814. First one fix the led which might
stay on even that there is no link. The second one improves increases
length of the cable that can be used when used in 1000Base-T.

When the length of the cable is more than 100m and the lan8814 is
configured to run in 1000Base-T Slave then the register of the device
needs to be optimized.
Workaround this by setting the measure time to a value of 0xb. This
value can be set regardless of the configuration.
This issue is described in 'LAN8814 Silicon Errata and Data Sheet
Clarification' and according to that, this will not be corrected in a
future silicon revision.

Lan8814 phy led behavior is not correct. It was noticed that the led
still remains ON when the cable is unplugged while there was traffic
passing at that time.
The fix consists in clearing bit 10 of register 0x38, in this way the
led behaviour is correct and gets OFF when there is no link.

With the removal of the ARCH_NR_GPIOS, the number of available GPIOs
is effectively unlimited, causing the gpio-mockup module load failure
test that overflowed the number of GPIOs to unexpectedly succeed, and
so fail.
The test is no longer relevant so remove it.
Promote the "no lines defined" test so there is still one load
failure test in the basic set.

Now WoWLAN firmware will disable PCIE DMA after driver call cfg_wake
function, and it will lead to release offload packet fail because driver
can't receive completion notification from firmware. We move release
offload packet earlier to avoid this error.
