cache.h contains some defines which are used to represent fields and
enumeration values which do not follow the standard naming convention used for
when we automatically generate defines for system registers. Update the
names of the constants to reflect standardised naming and move them to
sysreg.h.
There is also a helper CTR_L1IP() which was open coded and has been
converted to use SYS_FIELD_GET().

Future changes to generate register definitions automatically will cause
this header to be included in a linker script. This will mean that headers
it in turn includes that are not safe for use in such a context (eg, due
to the use of assembler macros) cause build problems. Avoid these issues by
moving the affected includes and associated defines to the section of the
file already guarded by ifndef __ASSEMBLY__.

In 155433cb36 ("arm64: cache: Remove support for ASID-tagged VIVT
I-caches") we removed all the support fir AIVIVT cache types and renamed
all references to the field to say "unknown" since support for AIVIVT
caches was removed from the architecture. Some confusion has resulted since
the corresponding change to the architecture left the value named as
AIVIVT but documented it as reserved in v8, refactor the code so we don't
define the constant instead. This will help with automatic generation of
this register field since it means we care less about the correspondence
with the ARM.
No functional change, the value displayed to userspace is unchanged.

Universal Serial Interface (USI) supports three types of serial interface
such as Universal Asynchronous Receiver and Transmitter (UART), Serial
Peripheral Interface (SPI), and Inter-Integrated Circuit (I2C).
Each protocols can be working independently and configured as one of
those using external configuration inputs.
Exynos Auto v9 SoC support 12 USIs. When a USI uses two pins such as i2c
and 3 wire uarts(RX/TX only), we can use remain two pins as i2c mode.
So, we can define one USI node that includes serial/spi and hsi2c.
usi_i2c nodes can be used only for i2c mode.
We can have below combinations for one USI.
1) The usi node is used either 4 pin uart or 4 pin spi
-> No usi_i2c can be used
2) The usi node is used 2 pin uart(RX/TX) and i2c(SDA/SCL)
-> usi_i2c should be enabled to use the latter i2c
3) The usi node is used i2c(SDA/SCL) and i2c(SDA/SCL)
-> usi_i2c should be enabled to use the latter i2c
By default, all USIs are initially set to uart mode by below setting.
samsung,mode = <USI_V2_UART>;
You can change it either USI_V2_SPI or USI_V2_I2C.

The first host interface has by default no interest in receiving packets
MAC DA de:ad:be:ef:13:37, so it might drop them before they hit the tc
filter and this might confuse the selftest.
Enable promiscuous mode such that the filter properly counts received
packets.

As mentioned in the blamed commit, flood_unicast_test() works by
checking the match count on a tc filter placed on the receiving
interface.
But the second host interface (host2_if) has no interest in receiving a
packet with MAC DA de:ad:be:ef:13:37, so its RX filter drops it even
before the ingress tc filter gets to be executed. So we will incorrectly
get the message "Packet was not flooded when should", when in fact, the
packet was flooded as expected but dropped due to an unrelated reason,
at some other layer on the receiving side.
Force h2 to accept this packet by temporarily placing it in promiscuous
mode. Alternatively we could either deliver to its MAC address or use
tcpdump_start, but this has the fewest complications.
This fixes the "flooding" test from bridge_vlan_aware.sh and
bridge_vlan_unaware.sh, which calls flood_test from the lib.

The Buck3 on DHCOR is used to supply IO voltage. It can output either 3V3
in the default DHCOR configuration, or 2V9 in case of AV96 DHCOR variant
which has extra Empirion DCDC converter in front of the 1V8 IO supply, or
outright 1V8 in case of 1V8 IO DHCOR without the Empirion DCDC converter.
The 2V9 mode in case of AV96 DHCOR variant is used to reduce unnecessarily
high input voltage to the Empirion DCDC converter, so move it into matching
DTSI to stop confusing users.

In rcar_gen2_regulator_quirk(), for_each_matching_node_and_match() will
automatically increase and decrease the refcount. However, we should
call of_node_get() for the new reference created in 'quirk->np'.
Besides, we also should call of_node_put() before the 'quirk' being
freed.

The 1st patch is by Oliver Hartkopp, targets the BCM CAN protocol and
converts a costly synchronize_rcu() to call_rcu() to fix a performance
regression.
Srinivas Neeli's patch for the xilinx_can driver drops the brp limit
down to 1, as only the pre-production silicon have an issue with a brp
of 1.
The next patch is by Duy Nguyen and fixes the data transmission on
R-Car V3U SoCs in the rcar_canfd driver.
Rhett Aultman's patch fixes a DMA memory leak in the gs_usb driver.
Liang He's patch removes an extra of_node_get() in the grcan driver.
The next 2 patches are by me, target the m_can driver and fix the
timestamp handling used for peripheral devices like the tcan4x5x.
Jimmy Assarsson contributes 3 patches for the kvaser_usb driver and
fixes CAN clock and bit timing related issues.
The remaining 5 patches target the mcp251xfd driver. Thomas Kopp
contributes 2 patches to improve the workaround for broken CRC when
reading the TBC register. 3 patches by me add a missing
hrtimer_cancel() during the ndo_stop() callback, and fix the reading
of the Device ID register.
