2021-06-09counter: stm32-lptimer-cnt: Add const qualifier for actions_list arrayWilliam Breathitt Gray1-1/+1
The struct counter_synapse actions_list member expects a const enum counter_synapse_action array. This patch adds the const qualifier to the stm32_lptim_cnt_synapse_actions to match actions_list.

2021-03-11counter: stm32-lptimer-cnt: remove iio counter abiFabrice Gasnier1-261/+36
Currently, the STM32 LP Timer counter driver registers into both IIO and counter subsystems, which is redundant. Remove the IIO counter ABI and IIO registration from the STM32 LP Timer counter driver since it's been superseded by the Counter subsystem as discussed in [1]. Keep only the counter subsystem related part. Move a part of the ABI documentation into a driver comment. This also removes a duplicate ABI warning $ scripts/get_abi.pl validate ... /sys/bus/iio/devices/iio:deviceX/in_count0_preset is defined 2 times: ./Documentation/ABI/testing/sysfs-bus-iio-timer-stm32:100 ./Documentation/ABI/testing/sysfs-bus-iio-lptimer-stm32:0 [1] https://lkml.org/lkml/2021/1/19/347 Acked-by: William Breathitt Gray <vilhelm.gray@gmail.com> Signed-off-by: Fabrice Gasnier <fabrice.gasnier@foss.st.com> Link: https://lore.kernel.org/r/1611926542-2490-1-git-send-email-fabrice.gasnier@foss.st.com Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>
2020-06-14iio: remove explicit IIO device parent assignmentAlexandru Ardelean1-1/+0
This patch applies the semantic patch: @@ expression I, P, SP; @@ I = devm_iio_device_alloc(P, SP); ... - I->dev.parent = P; It updates 302 files and does 307 deletions. This semantic patch also removes some comments like '/* Establish that the iio_dev is a child of the i2c device */' But this is is only done in case where the block is left empty. The patch does not seem to cover all cases. It looks like in some cases a different variable is used in some cases to assign the parent, but it points to the same reference. In other cases, the block covered by ... may be just too big to be covered by the semantic patch. However, this looks pretty good as well, as it does cover a big bulk of the drivers that should remove the parent assignment.

2019-10-18counter: Simplify the count_read and count_write callbacksWilliam Breathitt Gray1-3/+2
The count_read and count_write callbacks are simplified to pass val as unsigned long rather than as an opaque data structure. The opaque counter_count_read_value and counter_count_write_value structures, counter_count_value_type enum, and relevant counter_count_read_value_set and counter_count_write_value_get functions, are removed as they are no longer used.
