This adds a driver to communicate with the firmware running on the
secure processor of the Turris Mox router, enabling the kernel to
retrieve true random numbers from the Entropy Bit Generator and to read
some information burned into eFuses when device was manufactured:
and to
sign messages with the ECDSA private key burned into each Turris Mox
device when manufacturing.
This also adds support to read other information burned into eFuses:
- serial number
- board version
- MAC addresses
- RAM size
- ECDSA public key (this is not read directly from eFuses, rather it
is computed by the firmware as pair to the burned private key)
The source code of the firmware is open source and can be found at
https://gitlab.labs.nic.cz/turris/mox-boot-builder/tree/master/wtmi
The firmware is also able to, on demand, sign messages with the burned
ECDSA private key, but since Linux's akcipher API is not yet stable
(and therefore not exposed to userspace via netlink), this functionality
is not supported yet.

SAE J1939 is the vehicle bus recommended practice used for communication
and diagnostics among vehicle components. Originating in the car and
heavy-duty truck industry in the United States, it is now widely used in
other parts of the world.
J1939, ISO 11783 and NMEA 2000 all share the same high level protocol.
SAE J1939 can be considered the replacement for the older SAE J1708 and
SAE J1587 specifications.

Revised pull request to fix up a missing Signed-off-by and roll in
a fix in the lsm9ds1 support after I broke it when applying.
Revised again because the fix changed a hash meaning a fix
that previously followed it now had the wrong fixes tag.
A few fixes in here that could have gone a faster path but aren't quite
worth the rush for 5.3.
New device support
* ad7606
- Support the ad7606b which adds a software controlled mode alongside
the pin controlled only approach of the ad7606. Including dt-bindings.
* lsm6dsx
- Add support for the gyro and accelerometer part of the lsm9ds1 which is
a compound device also including a magnetometer (st_sensors driver).
Includes bindings and precursor rework of the driver.
Features
* ad7192
- Add support for low pass filter control.
- DT binding docs.
Cleanups and minor fixes
* MAINTAINERS
- Fix a typo in a path.
- Add entry for ad7606
* ad5380
- Fix a failure to dereference a pointer before atempting to assign the
value.
* ad7192
- Drop platform data as not used in mainline and we now have full DT bindings.
* ad7606
- YAML conversion for dt-bindings.
* adis16240
- Rework write_raw to make it more readable using GENMASK.
* adis16460
- Fix and issue with an unsigned variable holding potential negatives.
* cros_ec
- Fix missing default of calibration vector so that we get 'something'
before calibration is complete on a given axis.
* hid-sensors
- Use int_pow instead of opencoding.
* isl29501
- rename dt-binding docs to include renesas inline with other renesas parts
and general current convention.
* kxcjk1013
- Improve comments on the 'unusual' ACPI ids used to identify which sensor
is which in certain laptops.
* lsm6dsx
- Add one bit to the fifo status masks for a number of parts.
- Drop a reserved entry from the sensitivity values to tidy up interface.
- Use core conversion macro from G to m/s^2 for lsm9ds1 to make it easier
to relate to the datasheet and consistent with other parts supported.
* max1027
- Use device managed APIs to avoid manual error handling and cleanup.
* rfd77402
- Typo in Kconfig help.
* sc27xx
- Switch to polling mode from interrupts as interrupt handling typically
to slow for very short sleeps.
* st-sensors

is usually coupled with an RM-1500 or an RM-1800 remote control.
The scrollwheels on the RM-1800 remote are not bound, as they are

systems. They can be remapped using standard Linux keyboard
remapping tools.

The kryo cpufreq driver reads the nvmem cell and uses that data to
populate the opps. There are other qcom cpufreq socs like krait which
does similar thing. Except for the interpretation of the read data,
rest of the driver is same for both the cases. So pull the common things
out for reuse.

Backlight brightness curves can have different shapes. The two main
types are linear and non-linear curves. The human eye doesn't
perceive linearly increasing/decreasing brightness as linear (see
also 88ba95bedb79 "backlight: pwm_bl: Compute brightness of LED
linearly to human eye"), hence many backlights use non-linear (often
logarithmic) brightness curves. The type of curve currently is opaque
to userspace, so userspace often uses more or less reliable heuristics
(like the number of brightness levels) to decide whether to treat a
backlight device as linear or non-linear.
Export the type of the brightness curve via the new sysfs attribute
'scale'. The value of the attribute can be 'linear', 'non-linear' or
'unknown'. For devices that don't provide information about the scale
of their brightness curve the value of the 'scale' attribute is 'unknown'.

This commit adds myself as one of maintainers for firewire audio
drivers and IEC 61883-1/6 packet streaming engine. I call them ALSA
firewire stack as a whole.
6 years ago I joined in development for this category of drivers with
heavy reverse-engineering tasks and over 100 models are now available
from ALSA applications. IEEE 1394 bus itself and units on the bus are
enough legacy but the development still continues.
I have a plan to add drastic enhancement in kernel v5.5 and v5.6 period.
This commit adds myself into MAINTAINERS so that developers and users
can easily find active developer to post their issues, especially for
regression.

- vf610-bk4 fails to detect its flash due to an incorrect description
- meson-g12a USB phy configuration fails
- meson-g12b reboot should not power off the SD card
- Some corrections for apparently harmless differences from the
documentation.
Regression fixes:
- ams-delta FIQ interrupts broke in 5.3
- TI am3/am4 mmc controllers broke in 5.2
The logic_pio driver (used on some Huawei ARM servers) needs a few
bug fixes for reliability.

This is the i2c-icy driver for the ICY board for Amiga computers.
It connects a PCF8584 I2C controller to the Zorro bus, providing I2C
connectivity. The original documentation can be found on Aminet:
https://aminet.net/package/docs/hard/icy
IRQ support is currently not implemented, as i2c-algo-pcf is built for
the ISA bus and a straight implementation of the same stack locks up a
Zorro machine.

The new header is intended to be used by drivers using the backdoor.
Follow the KVM example using alternatives self-patching to choose
between vmcall, vmmcall and io instructions.
Also define two new CPU feature flags to indicate hypervisor support
for vmcall- and vmmcall instructions. The new XF86_FEATURE_VMW_VMMCALL
flag is needed because using XF86_FEATURE_VMMCALL might break QEMU/KVM
setups using the vmmouse driver. They rely on XF86_FEATURE_VMMCALL
on AMD to get the kvm_hypercall() right. But they do not yet implement
vmmcall for the VMware hypercall used by the vmmouse driver.
