The devctl register on musb is the only way to get state information
on musb. The hardware can easily get confused because it tries to do
things on it's own automagically, and things like slow VBUS rise can
make things fail.
Let's make it easier to debug the ongoing state change issues that
keep popping up on regular basis and add tracing support.
With these changes we can easily trace musb state change events with:
echo 1 > /sys/kernel/debug/tracing/events/musb/musb_state/enable
cat /sys/kernel/debug/tracing/trace_pipe
echo 0 > /sys/kernel/debug/tracing/events/musb/musb_state/enable

The driver adds support for generic CAN transceivers. Currently
the modes supported by this driver are standby and normal modes for TI
TCAN1042 and TCAN1043 CAN transceivers.
The transceiver is modelled as a phy with pins controlled by gpios, to put
the transceiver in various device functional modes. It also gets the phy
attribute max_link_rate for the usage of CAN drivers.

Now that the auxiliary_bus exists, there's no reason to use platform
devices as children of a PCI device any longer.
This patch refactors the code by extending a basic auxiliary device
with Intel link-specific structures that need to be passed between
controller and link levels. This refactoring is much cleaner with no
need for cross-pointers between device and link structures.
Note that the auxiliary bus API has separate init and add steps, which
requires more attention in the error unwinding paths. The main loop
needs to deal with kfree() and auxiliary_device_uninit() for the
current iteration before jumping to the common label which releases
everything allocated in prior iterations.

Register with kernel restart handler instead of setting arm_pm_restart
directly. This enables support for replacing the PSCI restart handler
with a different handler if necessary for a specific board.
Select a priority of 129 to indicate a higher than default priority, but
keep it as low as possible since PSCI reset is known to fail on some

The regmap is configured for 8 bit registers, uses a RB-Tree cache and
marks several registers as volatile (i.e. do not cache).
The ALS and PS data registers in the chip are 16 bit wide and spans
two regmap registers. In the current driver only the base register is
marked as volatile, resulting in the upper register only read once.
Further the data sheet notes:
| When the I2C read operation starts, all four ALS data registers are
| locked until the I2C read operation of register 0x8B is completed.
Which results in the registers never update after the 2nd read.
This patch fixes the problem by marking the upper 8 bits of the ALS
and PS registers as volatile, too.

Commit c1d1c4a62db5 ("iio: accel: bma180: BMA254 support") added
BMA254 support to the bma180 driver and changed some naming to BMA25x
to make it easier to add support for BMA253 and BMA255.
Unfortunately, there is quite some overlap between the bma180 driver
and the bmc150-accel driver. Back when the commit was made, the
bmc150-accel driver actually already had support for BMA255, and
adding support for BMA254 would have been as simple as adding a new
compatible to bmc150-accel.
The bmc150-accel driver is a bit better for BMA254 since it also
supports the motion trigger/interrupt functionality. Fortunately,
moving BMA254 support over to bmc150-accel is fairly simple because
the drivers have compatible device tree bindings.
Revert most of the changes for BMA254 support in bma180 and move
BMA254 over to bmc150-accel. This has the following advantages:
- Support for motion trigger/interrupt
- Fix incorrect scale values (BMA254 currently uses the same as
BMA250 but actually they're different because of 10 vs 12 bits
data size)
- Less code than before :)
BMA250 could be potentially also moved but it's more complicated
because its chip_id conflicts with the one for BMA222 in bmc150-accel.
Perhaps there are also other register differences, I did not investigate
further yet (and I have no way to test it).

BMA253 is mostly like BMA255 and has exactly the same register layout
as used by the bmc150-accel driver as far I can tell. Making it work
is as simple as adding new device IDs for it since it has the same
chip_id = 0xFA (250) as BMA255 and others.

The chips supported by the bmc150-accel driver are clearly documented
in Kconfig, in the bmc150_accel_chip_info_tbl as well as in all the
device ID tables in the I2C/SPI drivers. It's easy to forget to update
the lists in the file header. Drop those entirely to reduce the amount
of changes required to add new chip variants.

Commit 0ad4bf370176 ("iio:accel:bmc150-accel: Use the chip ID to detect
sensor variant") stopped using the I2C/ACPI match data to look up the
bmc150_accel_chip_info. However, the bmc150_accel_chip_info_tbl remained
as-is, with multiple entries with the same chip_id (e.g. 0xFA for
BMC150/BMI055/BMA255). This is redundant now because actually the driver
will always select the first entry with a matching chip_id.
So even if a device probes e.g. with BMA0255 it will end up using the
chip_info for BMC150. And in general that's fine for now, the entries
for BMC150/BMI055/BMA255 were exactly the same anyway (except for the
name, which is replaced with the more accurate one later).
But in this case it's misleading because it suggests that one should
add even more entries with the same chip_id when adding support for
new variants. Let's make that more clear by removing the enum with
the chip identifiers entirely and instead have only one entry per
chip_id.
Note that we may need to bring back some mechanism to differentiate
between different chips with the same chip_id in the future.
For example, BMA250 (currently supported by the bma180 driver) has the
same chip_id = 0x03 as BMA222 even though they have different channel
sizes (8 bits vs 10 bits). But in any case, that mechanism would
need to look quite different from what we have right now.

The Kconfig option currently says that all Bosch accelerometers
supported by the bmc150-accel driver are combo chips with both
accelerometer and magnetometer. This is wrong: actually only BMC150
is such a combo. The BMA* variants only contain an accelerometer
and the BMI055 actually is a accelerometer + gyroscope combo.
Clarify this in the help text and also make the list of supported
variants complete and sorted for consistency.

According to sysfs-bus-iio documentation the unit for accelerometer
values after applying scale/offset should be m/s^2, not g, which explains
why the scale values for the other variants in bmc150-accel do not match
exactly the values given in the datasheet.
To get the correct values, we need to multiply the BMA222 scale values
by g = 9.80665 m/s^2.

According to the BMA253 datasheet [1] and BMA250 datasheet [2] the
bandwidth value for BMA25x should be set as 01xxx:
"Settings 00xxx result in a bandwidth of 7.81 Hz; [...]
It is recommended [...] to use the range from ´01000b´ to ´01111b´
only in order to be compatible with future products."
However, at the moment the drivers sets bandwidth values from 0 to 6,
which is not recommended and always results into 7.81 Hz bandwidth
according to the datasheet.
Fix this by introducing a bw_offset = 8 = 01000b for BMA25x,
so the additional bit is always set for BMA25x.
