When a consumer calls iio_read_channel_processed() and no channel scale is available, it's assumed that the scale is one and the raw value is returned as expected. On the other hand, if the consumer calls iio_convert_raw_to_processed() the scaling factor requested by the consumer is not applied. This for example causes the consumer to process mV when expecting uV. Make sure to always apply the scaling factor requested by the consumer. Fixes: adc8ec5f ("iio: inkern: pass through raw values if no scaling") Signed-off-by:

x86 boards may use ACPI HID "TXNW1010" for the hdc100x device. TI told us "The ACPI ID for TI is: https://uefi.org/node/1028 (TXNW), therefore it would most likely be appropriate to use TXNW1010." So add an ACPI match table for that accordingly. Signed-off-by:

To convert SX9360 status register ["REG_STAT"], into a channel index, we need to right shift by |stat_offset|, not left shift. Also the PROXSTAT bit (3) is for channel 1 (PHM, Phase Measured), not (PHR, Phase Reference, channel 0), so the offset is 2 instead of 3.

Make use of the struct_size() helper instead of an open-coded version, in order to avoid any potential type mistakes or integer overflows that, in the worst scenario, could lead to heap overflows.

There's no need to use '__builtin_choose_expr' to choose the right call to 'adis_update_bits_base()'. We can change the 'BUILD_BUG_ON()' condition so that it makes sure only the supported sizes are passed in. With that, we can just use 'sizeof(val)' as the size argument of 'adis_update_bits_base()'.

sysfs_emit() is preferred over raw s*printf() for sysfs attributes since it knows about the sysfs buffer specifics and has some built-in checks for size and alignment. This patch converts the places in the IIO core that follow the pattern of return s*printf(...) to return sysfs_emit(...) This covers the new places that have been introduced where sprintf() is used for formatting sysfs output since the last time this was done in commit 83ca56b6 ("iio: core: Use sysfs_emit() (trivial bits)").

Initially this was designed to: | Fix sleeping in atomic context warning and a deadlock after iio_trigger_poll() | call | | If iio_trigger_poll() is called after IRQ was disabled, we will call | reenable_trigger() directly from hard IRQ or hrtimer context instead of | IRQ thread. In this case we will run in to multiple issue as sleeping in atomic | context and a deadlock. | | To avoid this issue, rework the trigger to use state machine. All state | changes are done over the hrtimer, so it allows us to drop fsleep() and | avoid the deadlock. Since this issue was fixed by: 9020ef65 ("iio: trigger: Fix a scheduling whilst atomic issue seen on tsc2046"). This patch is a cleanup to make state machine easier to follow. Signed-off-by:

This patch makes I2C and SPI interface drivers for STMicroelectronics sensor chips individually selectable via Kconfig. The default is kept unchanged - I2C and SPI interface drivers are still selected by default if the corresponding bus support is available. However, the patch makes it possible to explicitly disable drivers that are not needed for a particular target. Signed-off-by:
