iio: magnetometer: ak8975: drop incorrect AK09116 compatible

2024-10-04T14:38:22+00:00

[ Upstream commit da6e3160df230692bbd48a6d52318035f19595e2 ]

All compatibles in this binding without prefixes were deprecated, so
adding a new deprecated one after some time is not allowed, because it
defies the core logic of deprecating things.

Drop the AK09916 vendorless compatible.

iio: chemical: bme680: Fix read/write ops to device by adding mutexes

2024-10-04T14:38:21+00:00

[ Upstream commit 77641e5a477d428335cd094b88ac54e09ccb70f4 ]

Add mutexes in the {read/write}_raw() functions of the device to guard the
read/write of data from/to the device. This is necessary because for any
operation other than temperature, multiple reads need to take place from
the device. Even though regmap has a locking by itself, it won't protect us
from multiple applications trying to read at the same time temperature and
pressure since the pressure reading includes an internal temperature
reading and there is nothing to ensure that this temperature+pressure
reading will happen sequentially without any other operation interfering
in the meantime.

iio: adc: ad7606: fix standby gpio state to match the documentation

2024-10-04T14:38:21+00:00

[ Upstream commit 059fe4f8bbdf5cad212e1aeeb3e8968c80b9ff3b ]

The binding's documentation specifies that "As the line is active low, it
should be marked GPIO_ACTIVE_LOW". However, in the driver, it was handled
the opposite way. This commit sets the driver's behaviour in sync with the
documentation

iio: adc: ad7606: fix oversampling gpio array

2024-10-04T14:38:21+00:00

[ Upstream commit 8dc4594b54dbaaba40dc8884ad3d42083de39434 ]

gpiod_set_array_value was misused here: the implementation relied on the
assumption that an unsigned long was required for each gpio, while the
function expects a bit array stored in "as much unsigned long as needed
for storing one bit per GPIO", i.e it is using a bit field.

This leaded to incorrect parameter passed to gpiod_set_array_value, that
would set 1 value instead of 3.
It also prevents to select the software mode correctly for the AD7606B.

iio: imu: inv_mpu6050: fix interrupt status read for old buggy chips

2024-08-17T14:31:41+00:00

Interrupt status read seems to be broken on some old MPU-6050 like
chips. Fix by reverting to previous driver behavior bypassing interrupt
status read. This is working because these chips are not supporting
WoM and data ready is the only interrupt source.

iio: adc: ad7173: fix GPIO device info

2024-08-17T10:20:02+00:00

Models AD4114/5/6 have .higher_gpio_bits = true. This is not correct as
the only models that have the GPIO bits to a higher position are AD4111/2.

Fix by removing the higher_gpio_bits = true from the AD4114/5/6 models.

iio: adc: ad7124: fix DT configuration parsing

2024-08-06T16:03:22+00:00

The cfg pointer is set before reading the channel number that the
configuration should point to. This causes configurations to be shifted
by one channel.
For example setting bipolar to the first channel defined in the DT will
cause bipolar mode to be active on the second defined channel.

Fix by moving the cfg pointer setting after reading the channel number.

iio: adc: ad_sigma_delta: fix irq_flags on irq request

2024-08-06T15:57:24+00:00

With commit 7b0c9f8fa3d2 ("iio: adc: ad_sigma_delta: Add optional irq
selection"), we can get the irq line from struct ad_sigma_delta_info
instead of the spi device. However, in devm_ad_sd_probe_trigger(), when
getting the irq_flags with irq_get_trigger_type() we are still using
the spi device irq instead of the one used for devm_request_irq().

iio: adc: ads1119: Fix IRQ flags

2024-08-03T15:47:13+00:00

Remove IRQF_TRIGGER_FALLING flag from irq request, this should come from
the platform firmware and should not be hard-coded into the driver.

Add IRQF_ONESHOT flag to the irq request, the interrupt should not be
re-activated in interrupt context, it should be done only after the
device irq handler run.
