a16d8644ba Staging / IIO driver patches for 5.14-rc1
Here is the big set of IIO and staging driver patches for 5.14-rc1.
 
 Loads of IIO driver updates and additions in here, the shortlog has the
 full details.
 
 For the staging side, we moved a few drivers out of staging, and deleted
 the kpc2000 drivers as the original developer asked us to because no one
 was working on them anymore.
 
 Also in here are loads of coding style cleanups due to different intern
 projects focusing on the staging tree to try to get experience doing
 kernel development.
 
 All of these have been in the linux-next tree for a while with no
 reported problems.

Allocating an IRQ is conditional to the IRQ existence, but freeing it

e2a73c4e78 iio: accel: bmc150: Use more consistent and accurate scale values
It is quite strange that BMA222 and BMA222E have very close, yet
subtly different values in their scale tables. Comparing the datasheets
this is simply because the "Resolution" for the different measurement
ranges are documented with different precision.

For example, for +-2g the BMA222 datasheet [1] suggests a resolution
of 15.6 mg/LSB, while the BMA222E datasheet [2] suggests 15.63 mg/LSB.

Actually, there is no need to rely on the resolution given by the Bosch
datasheets. The resolution and scale can be calculated more consistently
and accurately using the range (e.g. +-2g) and the channel size (e.g. 8 bits).

Distributing 4g (-2g to 2g) over 8 bits results in an exact resolution
of (4g / 2^8) = 15.625 mg/LSB which is the same value as in both datasheets,
just slightly more accurate. Multiplying g = 9.80665 m/s^2 we get a more
accurate value for the IIO scale table.

Generalizing this we can calculate the scale tables more accurately using
(range / 2^bits) * g * 10^6 (because of IIO_VAL_INT_PLUS_MICRO).

Document this and make the scale tables more consistent and accurate
for all the variants using that formula. Now the scale tables for
BMA222 and BMA222E are consistent and probably slightly more accurate.

64f9dc6a68 iio: pressure: icp10100: Balance runtime pm + use pm_runtime_resume_and_get()
The devm_ handled runtime pm disable calls pm_runtime_put_sync_suspend()
which isn't balancing a matching get call.  It isn't a bug as such,
because the runtime pm core doesn't decrement the reference count below
zero, but it is missleading so let's drop it.

Using pm_runtime_resume_and_get() new call makes it easy to handle
failures in resume as it doesn't hold a reference count if it exits
with an error.

0e4f336f50 iio: chemical: atlas-sensor: Balance runtime pm + pm_runtime_resume_and_get()
The pm_runtime_put_noidle() call in remove isn't balanced with any get, so
drop it.  Note this isn't a bug as the runtime pm core will not allow the
reference count to go negative, making this a noop. However, it is
confusing to the reader so let's drop it.

pm_runtime_resume_and_get() replacement found using the coccicheck script
under review at:
https://lore.kernel.org/lkml/20210427141946.2478411-1-Julia.Lawall@inria.fr/

As pm_runtime_resume_and_get() returns <= 0 take advantage of that to
change the error checking to if (ret) which is more in keeping with the
rest of this driver.

This is a prequel to taking a closer look at the runtime pm in IIO drivers
in general.

The ltr559 chip uses only the lowest bit of the ALS_CONTR register to
configure between active and stand-by mode. In the original driver
BIT(1) is used, which does a software reset instead.

This patch fixes the problem by using BIT(0) as als_mode_active for
the ltr559 chip.

2ac0b029a0 iio: ltr501: mark register holding upper 8 bits of ALS_DATA{0,1} and PS_DATA as volatile, too
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.

a7ba1c24da iio: accel: bma180/bmc150: Move BMA254 to bmc150-accel driver
Commit c1d1c4a62d ("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).

c06a6aba68 iio: accel: bmc150: Drop misleading/duplicate chip identifiers
Commit 0ad4bf3701 ("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.

8090d67421 iio: accel: bma180: Fix BMA25x bandwidth register values
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.

a BOSC0200 ACPI device (and make it return false otherwise).

This is a preparation patch for adding special handling for other
ACPI HIDs (the "DUAL250E" HID).

addab6febc iio: accel: bmc150: Add support for DUAL250E ACPI DSM for setting the hinge angle
Some 360 degree hinges (yoga) style 2-in-1 devices use 2 bmc150 accels
to allow the OS to determine the angle between the display and the base
of the device, so that the OS can determine if the 2-in-1 is in laptop
or in tablet-mode.

On Windows both accelerometers are read (polled) by a special service
and this service calls the DSM (Device Specific Method), which in turn
translates the angles to one of laptop/tablet/tent/stand mode and then
notifies the EC about the new mode and the EC then enables or disables
the builtin keyboard and touchpad based in the mode.

When the 2-in-1 is powered-on or resumed folded in tablet mode the
EC senses this independent of the DSM by using a HALL effect sensor
which senses that the keyboard has been folded away behind the display.

At power-on or resume the EC disables the keyboard based on this and
the only way to get the keyboard to work after this is to call the
DSM to re-enable it.

Call the DSM on probe() and resume() to fix the keyboard not working
when powered-on / resumed in tablet-mode.

This patch was developed and tested on a Lenovo Yoga 300-IBR.

35157f443b iio: accel: bmc150: Remove bmc150_set/get_second_device() accessor functions
Now that the definition of the bmc150_accel_data struct is no longer
private to bmc150-accel-core.c, bmc150-accel-i2c.c can simply directly
access the second_dev member and the accessor functions are no longer
necessary.

Note if the i2c_acpi_new_device() for the second-client now fails,
an ERR_PTR gets stored in data->second_dev this is fine since it is only
ever passed to i2c_unregister_device() which has an IS_ERR_OR_NULL() check.

ba8bd0b33b iio: accel: bmc150: Move struct bmc150_accel_data definition to bmc150-accel.h
Further patches to bmc150-accel-i2c.c need to store some extra info
(on top of the second_dev pointer) in the bmc150_accel_data struct,
rather then adding yet more accessor functions for this lets just
move the struct bmc150_accel_data definition to bmc150-accel.h.
