iio: ssp_sensors: fix error code in ssp_print_mcu_debug()

2021-10-20T09:57:52+00:00

commit 4170d3dd1467e9d78cb9af374b19357dc324b328 upstream.

The ssp_print_mcu_debug() function should return negative error codes on
error.  Returning "length" is meaningless.  This change does not affect
runtime because the callers only care about zero/non-zero.

iio: ssp_sensors: add more range checking in ssp_parse_dataframe()

2021-10-20T09:57:52+00:00

commit 8167c9a375ccceed19048ad9d68cb2d02ed276e0 upstream.

The "idx" is validated at the start of the loop but it gets incremented
during the iteration so it needs to be checked again.

iio: hid-sensors: Update header includes

2021-06-16T13:53:13+00:00

General driver churn doesn't always include updates of header includes.
Manual review of the output of the include-what-you-use checker lead to the
following cleanup. Hopefuly this brings things back to a good state for the
hid-sensor drivers.

iio: hid-sensors: lighten exported symbols by moving to IIO_HID namespace

2021-06-16T13:53:13+00:00

A namespace for exported symbols makes clear who is a provider
and who is a consumer of the certain resources. Besides that,
it doesn't pollute the common namespace.

iio: hid: trigger: Balance runtime pm + use pm_runtime_resume_and_get()

2021-06-03T17:24:12+00:00

The call to pm_runtime_put_noidle() in remove() callback is not
balanced by any gets

Note this doesn't cause any problems beyond reader confusion as the runtime
pm core protects against the reference counter going negative.

Whilst here, use pm_runtiem_resume_and_get() to simplify code a little.

iio: core: move @id from struct iio_dev to struct iio_dev_opaque

2021-05-17T12:49:13+00:00

Continuing from Alexandru Ardelean's introduction of the split between
driver modifiable fields and those that should only be set by the core.

This could have been done in two steps to make the actual move after
introducing iio_device_id() but there seemed limited point to that
given how mechanical the majority of the patch is.

Includes fixup from Alex for missing mxs-lradc-adc conversion.

iio: hid-sensors: select IIO_TRIGGERED_BUFFER under HID_SENSOR_IIO_TRIGGER

2021-05-10T13:01:48+00:00

During commit 067fda1c065ff ("iio: hid-sensors: move triggered buffer
setup into hid_sensor_setup_trigger"), the
iio_triggered_buffer_{setup,cleanup}() functions got moved under the
hid-sensor-trigger module.

The above change works fine, if any of the sensors get built. However, when
only the common hid-sensor-trigger module gets built (and none of the
drivers), then the IIO_TRIGGERED_BUFFER symbol isn't selected/enforced.

Previously, each driver would enforce/select the IIO_TRIGGERED_BUFFER
symbol. With this change the HID_SENSOR_IIO_TRIGGER (for the
hid-sensor-trigger module) will enforce that IIO_TRIGGERED_BUFFER gets
selected.

All HID sensor drivers select the HID_SENSOR_IIO_TRIGGER symbol. So, this
change removes the IIO_TRIGGERED_BUFFER enforcement from each driver.

2021-04-26T19:11:52+00:00

Pull ARM SoC driver updates from Arnd Bergmann:
 "Updates for SoC specific drivers include a few subsystems that have
  their own maintainers but send them through the soc tree:

  TEE/OP-TEE:
   - Add tracepoints around calls to secure world

  Memory controller drivers:
   - Minor fixes for Renesas, Exynos, Mediatek and Tegra platforms
   - Add debug statistics to Tegra20 memory controller

  ARM SCMI Firmware:
   - Support for modular SCMI protocols and vendor specific extensions
   - New SCMI IIO driver
   - Per-cpu DVFS

  The other driver changes are all from the platform maintainers
  directly and reflect the drivers that don't fit into any other
  subsystem as well as treewide changes for a particular platform.

  SoCFPGA:
   - Various cleanups contributed by Krzysztof Kozlowski

  Mediatek:
   - add MT8183 support to mutex driver
   - MMSYS: use per SoC array to describe the possible routing

     avoid issues with missing resources and unnecessary deferred probe
   - ti-sysc debug option can now detect more devices
   - ti-sysc now warns if an old incomplete devicetree data is found as
     we now rely on it being complete for am3 and 4
   - soc init code needs to check for prcm and prm nodes for omap4/5 and
     dra7
   - omap-prm driver needs to enable autoidle retention support for
     omap4
   - omap5 clocks are missing gpmc and ocmc clock registers
   - pci-dra7xx now needs to use builtin_platform_driver instead of
     using builtin_platform_driver_probe for deferred probe to work

  Raspberry Pi:
   - Fix-up all RPi firmware drivers so as for unbind to happen in an
     orderly fashion
   - Support for RPi's PoE hat PWM bus

  Qualcomm
   - Improved detection for SCM calling conventions
