This commit adds the 'usb_type' property to represent USB supplies
which can report a number of different types based on a connection
event.
Examples of this already exist in drivers whereby the existing 'type'
property is updated, based on an event, to represent what was
connected (e.g. USB, USB_DCP, USB_ACA, ...). Current implementations
however don't show all supported connectable types, so this knowledge
has to be exlicitly known for each driver that supports this.
The 'usb_type' property is intended to fill this void and show users
all possible USB types supported by a driver. The property, when read,
shows all available types for the driver, and the one currently chosen
is highlighted/bracketed. It is expected that the 'type' property
would then just show the top-level type 'USB', and this would be
static.
Currently the 'usb_type' enum contains all of the USB variant types
that exist for the 'type' enum at this time, and in addition has
SDP and PPS types. The mirroring is intentional so as to not impact
existing usage of the 'type' property.

Currently there's no error checking of this parameter in the
registration function and it's blindly added to psy class and
subsequently used as is. For example if this is NULL the call
to psy_register_thermal() will try to dereference the pointer
thus causing a kernel dump.
This commit updates the registration code to add some basic
checks on the desc pointer validity, name, and presence of
properties.

Some low-speed and full-speed devices (for example, bluetooth)
do not have time to initialize. For them, ETIMEDOUT is a valid error.
We need to give them another try. Otherwise, they will
never be initialized correctly and in dmesg will be messages
"Bluetooth: hci0 command 0x1002 tx timeout" or similars.

rx_lanes and tx_lanes sysfs entries show the number of lanes in use by a
device.
USB 3.2 adds support for Dual-lane (symmetrical), using 2 rx lanes and
2 tx lanes for normal non Inter-Chip SSIC devices.
USB 3.1 and older are all single lane.
SSIC devices can have up to 4 lanes per direction in use,
with different number of rx and tx lanes.

USB 3.2 specification adds a Gen XxY notion for USB3 devices where
X is the signaling rate on the wire. Gen 1xY is 5Gbps Superspeed
and Gen 2xY is 10Gbps SuperSpeedPlus. Y is the lane count.
For normal, non inter-chip (SSIC) devies the rx and tx lane count is
symmetric, and the maximum lane count for USB 3.2 devices is 2 (dual-lane).
SSIC devices may have asymmetric lane counts, with up to four
lanes per direction. The USB 3.2 specification doesn't point out
how to use the Gen XxY notion for these devices, so we limit the Gen Xx2
notion to symmertic Dual lane devies.
For other devices just show Gen1 or Gen2
Gen 1 5Gbps
Gen 2 10Gbps
Gen 1x2 10Gbps Dual-lane (USB 3.2)

USB 3.2 specification adds Dual-lane support, doubling the maximum
SuperSpeedPlus data rate from 10Gbps to 20Gbps.
Dual-lane takes into use a second set of rx and tx wires/pins in the
Type-C cable and connector.
Add "rx_lanes" and "tx_lanes" variables to struct usb_device to store
the numer of lanes in use. Number of lanes can be read using the extended
port status hub request that was introduced in USB 3.1.
Extended port status rx and tx lane count are zero based, maximum
lanes supported by non inter-chip (SSIC) USB 3.2 is 2 (dual lane) with
rx and tx lane count symmetric. SSIC devices support asymmetric lanes
up to 4 lanes per direction.
If extended port status is not available then default to one lane.

clock is optional because not all the SoCs using this IP need it but at
least for Armada 7K/8K it is actually mandatory.
The change was done at xhci-plat level and not at a xhci-mvebu.c because,
it is expected that other SoC would have this kind of constraint.

Remove dependencies on HAS_DMA where a Kconfig symbol depends on another
symbol that implies HAS_DMA, and, optionally, on "|| COMPILE_TEST".
In most cases this other symbol is an architecture or platform specific
symbol, or PCI.
Generic symbols and drivers without platform dependencies keep their
dependencies on HAS_DMA, to prevent compiling subsystems or drivers that
cannot work anyway.
This simplifies the dependencies, and allows to improve compile-testing.

Pull more Kbuild updates from Masahiro Yamada:
- pass HOSTLDFLAGS when compiling single .c host programs
- build genksyms lexer and parser files instead of using shipped
versions
- rename *-asn1.[ch] to *.asn1.[ch] for suffix consistency
- let the top .gitignore globally ignore artifacts generated by flex,
bison, and asn1_compiler
- let the top Makefile globally clean artifacts generated by flex,
bison, and asn1_compiler
- use safer .SECONDARY marker instead of .PRECIOUS to prevent
intermediate files from being removed
- support -fmacro-prefix-map option to make __FILE__ a relative path
- fix # escaping to prepare for the future GNU Make release
- clean up deb-pkg by using debian tools instead of handrolled
source/changes generation
- improve rpm-pkg portability by supporting kernel-install as a
fallback of new-kernel-pkg
- extend Kconfig listnewconfig target to provide more information

Pull x86 fixes from Thomas Gleixner:
"A set of fixes and updates for x86:
- Address a swiotlb regression which was caused by the recent DMA
rework and made driver fail because dma_direct_supported() returned
false
- Fix a signedness bug in the APIC ID validation which caused invalid
APIC IDs to be detected as valid thereby bloating the CPU possible
space.
- Fix inconsisten config dependcy/select magic for the MFD_CS5535
driver.
- Fix a corruption of the physical address space bits when encryption
has reduced the address space and late cpuinfo updates overwrite
the reduced bit information with the original value.
- Dominiks syscall rework which consolidates the architecture
specific syscall functions so all syscalls can be wrapped with the
same macros. This allows to switch x86/64 to struct pt_regs based
syscalls. Extend the clearing of user space controlled registers in
the entry patch to the lower registers"

Pull x86 pti updates from Thomas Gleixner:
"Another series of PTI related changes:
- Remove the manual stack switch for user entries from the idtentry
code. This debloats entry by 5k+ bytes of text.
- Use the proper types for the asm/bootparam.h defines to prevent
user space compile errors.
- Use PAGE_GLOBAL for !PCID systems to gain back performance
- Prevent setting of huge PUD/PMD entries when the entries are not
leaf entries otherwise the entries to which the PUD/PMD points to
and are populated get lost"

Pull scheduler fixes from Thomas Gleixner:
"A few scheduler fixes:
- Prevent a bogus warning vs. runqueue clock update flags in

- Simplify the helper functions which handle requests for skipping
the runqueue clock updat.
- Do not unlock the tunables mutex in the error path of the cpu
frequency scheduler utils. Its not held.
- Enforce proper alignement for 'struct util_est' in sched_avg to
prevent a misalignment fault on IA64"
