https://lore.kernel.org/all/20220405135758.774016-1-catalin.marinas@arm.com/
mm, arm64: Reduce ARCH_KMALLOC_MINALIGN brought to my attention that
our current IIO usage of L1CACHE_ALIGN is insufficient as their are Arm
platforms out their with non coherent DMA and larger cache lines at
at higher levels of their cache hierarchy.
Rename the define to make it's purpose more explicit. It will be used
much more widely going forwards (to replace incorrect ____cacheline_aligned
markings.
Note this patch will greatly reduce the padding on some architectures
that have smaller requirements for DMA safe buffers.
The history of changing values of ARCH_KMALLOC_MINALIGN via
ARCH_DMA_MINALIGN on arm64 is rather complex. I'm not tagging this
as fixing a particular patch from that route as it's not clear what to tag.
Most recently a change to bring them back inline was reverted because
of some Qualcomm Kryo cores with an L2 cache with 128-byte lines
sitting above the point of coherency.
c1132702c7 Revert "arm64: cache: Lower ARCH_DMA_MINALIGN to 64 (L1_CACHE_BYTES)"
That reverts:
65688d2a05 arm64: cache: Lower ARCH_DMA_MINALIGN to 64 (L1_CACHE_BYTES) which
refers to the change originally being motivated by Thunder x1 performance
rather than correctness.

Different from SCA3300, SCL3300 can output inclination angles.
Angles are formed from acceleration with following equations:
ANG_X = atan2(accx , sqrt(pow(accy , 2) + pow(accz , 2)))
ANG_Y = atan2(accy , sqrt(pow(accx , 2) + pow(accz , 2)))
ANG_Z = atan2(accz , sqrt(pow(accx , 2) + pow(accy , 2)))
The commit adds the output of the raw value, scale
and scale_available of angles.
New interfaces:
in_incli_scale
in_incli_scale_available
in_incli_x_raw
in_incli_y_raw
in_incli_z_raw
Data converted by application of scale to degrees.

iio: accel: bmi088: modified the device name
It is possible to have multiple sensors connected on the same platform.
For support of different sensors, making it possible to obtain the
device name by reading the chip id. If the device was found in the
table but the device tree binding is different, the driver will carry
on with a warning. If no matching device was found, the driver load
the binding chip info.
Tested case, test with bmi085 and bmi090 patches applied:
connect 3 bmi090l to the system, and set device tree compatible:
spi2.0: compatible = "bosch,bmi090l-accel";
spi2.2: compatible = "bosch,bmi088-accel";
spi2.4: compatible = "bosch,bmi085-accel";
Get a warning for the mismatched devices:

Currently, the driver updates the FIFO watermark inside both
update_scan_mode() and hwfifo_set_watermark(). Inside the IIO core,
hwfifo_set_watermark() is called immediately after update_scan_mode(),
making the first call to set_fifo_samples() redundant.
Remove the first call to set_fifo_samples(), and merge the
set_fifo_samples() function into the set_fifo_watermark()
function. Also, since fifo_set_size is always set inside of
update_scan_mode(), and it cannot be set to 0, remove the
zero check from set_fifo_samples().

Returning an error value in an i2c remove callback results in an error
message being emitted by the i2c core, but otherwise it doesn't make a
difference. The device goes away anyhow and the devm cleanups are
called.
As isl29028_clear_configure_ret() already emits an error message on
failure and the additional error message by the i2c core doesn't add any
useful information, change the return value to zero to suppress this
message.

Here is the large set of char, misc, and other driver subsystem updates
for 5.19-rc1. The merge request for this has been delayed as I wanted
to get lots of linux-next testing due to some late arrivals of changes
for the habannalabs driver.
Highlights of this merge are:
- habanalabs driver updates for new hardware types and fixes and
other updates
- IIO driver tree merge which includes loads of new IIO drivers
and cleanups and additions
- PHY driver tree merge with new drivers and small updates to
existing ones
- interconnect driver tree merge with fixes and updates
- soundwire driver tree merge with some small fixes
- coresight driver tree merge with small fixes and updates
- mhi bus driver tree merge with lots of updates and new device
support
- firmware driver updates
- fpga driver updates
- lkdtm driver updates (with a merge conflict, more on that
below)
- extcon driver tree merge with small updates
- lots of other tiny driver updates and fixes and cleanups, full
details in the shortlog.
All of these have been in linux-next for almost 2 weeks with no reported
problems.
Note, there are 3 merge conflicts when merging this with your tree:
- MAINTAINERS, should be easy to resolve
- drivers/slimbus/qcom-ctrl.c, should be straightforward
resolution
- drivers/misc/lkdtm/stackleak.c, not an easy resolution. This
has been noted in the linux-next tree for a while, and
resolved there, here's a link to the resolution that Stephen
came up with and that Kees says is correct:
https://lore.kernel.org/r/20220509185344.3fe1a354@canb.auug.org.au
I will be glad to provide a merge point that contains these resolutions
if that makes things any easier for you.

the current mode.

The call to check if the calibration is all zeroes is doing
it wrong: memchr_inv() returns NULL if the the calibration
contains all zeroes, but the check is for != NULL.
Fix it up. It's probably not an urgent fix because the inner
check for BIT(7) in data[13] will save us. But fix it.

Since commit 9bcf15f75c ("iio: adc: axp288: Fix TS-pin handling") we
preserve the bias current set by the firmware at boot. This fixes issues
we were seeing on various models.
Some models like the Nuvision Solo 10 Draw tablet actually need the
old hardcoded 80ųA bias current for battery temperature monitoring
to work properly.
Add a quirk entry for the Nuvision Solo 10 Draw to the DMI quirk table
to restore setting the bias current to 80ųA on this model.

This function (up to now) returns zero unconditionally, so there isn't
any benefit of returning a value. Make it return void to be able to see

The extended clocks are optional and may not be present for some
configurations supported by this driver. Nevertheless, in case
the clock is provided but some error happens during its getting,
that error handling should be done properly.

dev_err_probe() to handle properly -EPROBE_DEFER error.
