Replace of_property_read_u32() with device_property_read_u32(), when reading the amstaos,cover-comp-gain.This opens up the possibility of passing the properties during platform instantiation of the device by a suitable populated struct property_entry. Additionally, a minor change in logic is added to remove the of_node present check. Signed-off-by:

The only usage of mma8452_event_attribute_group is to assign its address to the event_attrs field in the iio_info struct, which is a const pointer. Make it const to allow the compiler to put it in read-only memory. This was the only non-const static struct in drivers/iio. Signed-off-by:

This change removes the old platform data for ad7298. It is only used to provide whether to use an external regulator as a reference. So, the logic is inverted a bit. The driver now tries to obtain a regulator. If one is provided, then the external ref is used. The rest of the logic should work as before. Signed-off-by:

Fixes IIO_VAL_FRACTIONAL for case when the result is negative and exponent is 0. example: if the result is -0.75, tmp0 will be 0 and tmp1 = 75 This causes the output to lose sign because of %d in snprintf which works for tmp0 <= -1.

The order in which 'users' counter is decremented vs calling drivers' close() method is implementation specific, and we should not rely on it. Let's introduce driver private flag and use it to signal ISR to exit when device is being closed. This has a side-effect of fixing issue of accessing inut->users outside of input->mutex protection.

Add support for setting the hysteresis as a shifted value of a channel's proximity threshold. Each channel can have a different threshold, but the hysteresis applies to all channels as a right shift factor. Therefore, duplicate the hysteresis value across all channels and make it depend on the channel's proximity threshold. This is sort of odd but seems to work in practice as most of the time only one channel is used. Signed-off-by:

This change inverts/reworks the logic to use an external reference via a provided regulator. Now the driver tries to obtain a regulator. If one is found, then it is used. The rest of the driver logic already checks if there is a non-NULL reference to a regulator, so it should be fine. Signed-off-by:

The AT91 ADC driver no longer uses the 'at91_add_device_adc' platform data type. This is no longer used (at least in mainline boards). This change removes the platform-data initialization from the driver, since it is mostly dead code now. Some definitions [from the platform data at91_adc.h include] have been moved in the driver, since they are needed in the driver. Signed-off-by:

This tries to solve a warning reported by the lkp bot: >> drivers/iio/adc/at91_adc.c:1439:34: warning: unused variable >> 'at91_adc_dt_ids' [-Wunused-const-variable] static const struct of_device_id at91_adc_dt_ids[] = { ^ 1 warning generated. This warning has appeared after the AT91_ADC driver compilation has been enabled via the COMPILE_TEST symbol dependency. The warning is caused by the 'of_match_ptr()' helper which returns NULL if OF is undefined. This driver should build only for device-tree context, so a dependency on the OF Kconfig symbol has been added. Also, the usage of of_match_ptr() helper has been removed since it shouldn't ever return NULL (because the driver should not be built for the non-OF context).

The main intent is to get rid of the cast for the void-pointer returned by of_device_get_match_data(). This requires const-ifying the 'caps' and 'registers' references on the at91_adc_state struct. The caps can be obtained also from the old platform_data (in the at91_adc_probe_pdata() function), but that cast is not touched in this patch, since the old platform_data should be removed/cleaned-away. Also, that cast deals with converting a kernel_ulong_t type to a pointer. So, updating that cast doesn't yield any benefit. Signed-off-by:

This is a small tidy-up. The of_device_get_match_data() helper retrieves the driver data from the OF table, without needed to explicitly know the table variable (since it can retrieve it from the driver object). Signed-off-by:

The AD5338R is a 10-bit DAC with 2 outputs and an internal 2.5V reference (enabled by default). The register configuration is nearly identical to the AD5696R DAC that's already supported by this driver, with the channel selection bits being the only thing different. Signed-off-by:
