* iio: accel: kxcjk1013: Add KIOX010A ACPI Hardware-IDHans de Goede2018-11-251-0/+1
| | | | | | | | | | | | | | Various 2-in-1's use KIOX010A and KIOX020A as HIDs for 2 KXCJ91008 accelerometers. The KIOX010A HID is for the one in the base and the KIOX020A for the accelerometer in the keyboard. Since userspace does not have a way yet to deal with (or ignore) the accelerometer in the keyboard, this commit just adds the KIOX010A HID for now so that display rotation will work.

* Staging: iio: adt7316: Add of_device_id tableShreeya Patel2018-11-251-0/+13
| | | | | | | | | | | | | | | When the kernel starts up, it kicks off compiled-in drivers that match “compatible” entries it finds in the device tree. At a later stage (when /lib/modules is available), all kernel modules that match “compatible” entries in the device tree are loaded. But if there is no dt table then there should be a fall back path with which desired kernel modules can be loaded. Hence, add of_device_id table in the i2c driver to be able to use when there is no dt table.

* iio: adc: meson-saradc: fix internal clock namesMartin Blumenstingl2018-11-251-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | Before this patch we are registering the internal clocks (for example on Meson8b, where the SAR ADC IP block implements the divider and gate clocks) with the following names: - /soc/cbus@c1100000/adc@8680#adc_div - /soc/cbus@c1100000/adc@8680#adc_en This is bad because the common clock framework uses the clock to create a directory in <debugfs>/clk. With such name, the directory creation (silently) fails and the debugfs entry ends up being created at the debugfs root. With this change, the new clock names are: - c1108680.adc#adc_div - c1108680.adc#adc_en This matches the clock naming scheme used in the PWM, Ethernet and MMC drivers. It also fixes the problem with debugfs. The idea is shamelessly taken from commit b96e9eb62841c5 ("pwm: meson: Fix mux clock names").

On error meson_sar_adc_clk_init() returns negative values so -ENOMEM in the (unlikely) failure case of devm_kasprintf() should be fine here.

| | | | | | | | | | | | | | | | | Let's make sure that the one registering a workgroup will also take the primary work lock at first for two reasons: 1) There's no need to introduce such a race window (and consequently overhead) between registering and locking, other tasks could break in by chance, and the race seems unnecessary (no benefit at all); 2) It's better to take the primary work when a workgroup is registered to apply the cache managed policy, for example, if some other tasks break in, it could turn into the in-place decompression rather than use as the cached decompression.

| | | | | | | | | | | | | | | | | | | `z_erofs_vle_workgroup' is heavily generated in the decompression, for example, it resets 32 bytes redundantly for 64-bit platforms even through Z_EROFS_VLE_INLINE_PAGEVECS + Z_EROFS_CLUSTER_MAX_PAGES, default 4, pages are stored in `z_erofs_vle_workgroup'. As an another example, `struct mutex' takes 72 bytes for our kirin 64-bit platforms, it's unnecessary to be reseted at first and be initialized each time. Let's avoid filling all `z_erofs_vle_workgroup' with 0 at first since most fields are reinitialized to meaningful values later, and pagevec is no need to initialized at all.

| | | | | | | | | | | | | | | | | | | | | | | | | When the managed cache is enabled, the last reference count of a workgroup must be used for its workstation.

Lets not rely on that. - Ensure gain update is only used with the ad778x chips that actually support it. - Tidy up pattern mask generation. - Read regulator when scale is requested (which should be infrequent) as it might have changed from initialization. * ad7816 - Move to modern gpio descriptors - Don't use a busy_pin for ad7818 as there isn't one. - Ensure RD/WR and CONVST pins are outputs (previously they were brought up as inputs which doesn't seem to make any sense) - DT id table. * adc128s052 - SPDX * adt7316 - Alignment fix. - Fix data reading. When using I2C the driver never actually used the value read. This has been broken a very long time hence no rush to fix it now + the driver is undergoing a lot of cleanup. - Sanity check that the i2c read didn't fail to actually read anything. * dpot-dac - Mark a switch full through with slightly different text so that gcc doesn't warn on it. * gyro-adc - Fix a wrong file in the MAINTAINERS entry and add binding doc to the listed files. * ina2xx - Add some early returns to clarify error paths in switch. * lsm6dsx - MAINTAINERS entry. * max11100 - SPDX * max9611 - SPDX * mcp4131 - use of_device_get_match_data in preference to spi_get_device_id approach. * rcar-adc - SPDX * sc27xx - Add ADC conversion timeout support to avoid possible fault. * ssp_sensors - Don't free managed resources manually. * st-magn - Add a comment to avoid future confusion over when to use -magn postfix (on multi chip in package parts) - Add BDU register for LIS3MDL where it seems to have been missed. * st-sensors - Minor spelling, grammar etc fixes. * tpl0102 - Use a pointer rather than an index of an array to improve conciseness. * tag 'iio-for-4.21a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio: (80 commits) Staging: iio: adt7316: Add an extra check for 'ret' equals to 0 Staging: iio: adt7316: Fix i2c data reading, set the data field dt-bindings: iio: adc: Add docs for ad7124 iio: adc: Add ad7124 support dt-bindings: iio: adc: Add common ADCs properties to a separate file iio: ad_sigma_delta: Allow to provide custom data register address staging: iio: ad7816: Add device tree table. iio: imu: st_lsm6dsx: add entry in MAINTAINERS file iio: potentiometer: mcp4131: use of_device_get_match_data() staging: iio: adc: ad7280a: use devm_* APIs staging: iio: adc: ad7280a: power down the device on error in probe dt-bindings: iio: imu: st_lsm6dsx: add support to i2c pullup resistors iio: imu: st_lsm6dsx: add hw FIFO support to i2c controller iio: imu: st_lsm6dsx: add st_lsm6dsx_push_tagged_data routine iio: imu: st_lsm6dsx: add i2c embedded controller support iio: imu: st_lsm6dsx: introduce st_lsm6dsx_sensor_set_enable routine iio: imu: st_lsm6dsx: introduce ST_LSM6DSX_ID_EXT sensor ids iio: imu: st_lsm6dsx: remove static from st_lsm6dsx_set_watermark iio: imu: st_lsm6dsx: reload trimming parameter at bootstrap iio: imu: st_lsm6dsx: introduce locked read/write utility routines ...

| | | | | | | | | | | | | | | | | | ret = 0 indicates a case of no error but no data read from the bus which is an invalid case. This case doesn't ever happen in reality. It should perhaps be handled for correctness though. Signed-off-by: Shreeya Patel <shreeya.patel23498@gmail.com> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>

| | | | | | | | | | | | | | | | | | | | | | | | adt7316_i2c_read function nowhere sets the data field. It is necessary to have an appropriate value for it. Hence, assign the value stored in 'ret' variable to data field. This is an ancient bug, and as no one seems to have noticed, probably no sense in applying it to stable.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ad7124-4 and ad7124-8 are a family of 4 and 8 channel sigma-delta ADCs with 24-bit precision and reference. Three power modes are available which in turn affect the output data rate: * Full power: 9.38 SPS to 19,200 SPS * Mid power: 2.34 SPS to 4800 SPS * Low power: 1.17 SPS to 2400 SPS The ad7124-4 can be configured to have four differential inputs, while ad7124-8 can have 8. Moreover, ad7124 also supports per channel configuration. Each configuration consists of gain, reference source, output data rate and bipolar/unipolar configuration.

| | | | | | | | | | | | | | | | | | | | | | Some newer devices from the Sigma-Delta ADC family do have their data register at a different address than the current default address. Add a parameter to the ad_sigma_delta_info struct which allows to override the default address.
