[ Upstream commit 01f68f067dc39df9c9d95d759ee61517eb4b0fcf ] 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 Remove the IIO counter ABI and IIO registration from the STM32 LP Timer counter driver since it's been superseded by the Counter subsystem as discussed in [1].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> Signed-off-by: Sasha Levin <sashal@kernel.org>

This enables counter device support through the Generic Counter

interface. You only need to enable this, if you also want to enable

one or more of the counter device drivers below.

Say yes here to build support for the ACCES 104-QUAD-8 quadrature
|

encoder counter/interface device family (104-QUAD-8, 104-QUAD-4).

|
|
A counter's respective error flag may be cleared by performing a write
|
|
operation on the respective count value attribute. Although the
|
|
104-QUAD-8 counters have a 25-bit range, only the lower 24 bits may be
|
|
set, either directly or via the counter's preset attribute. Interrupts
|
|
are not supported by this driver.
|
|
|
|
The base port addresses for the devices may be configured via the base
|
|
array module parameter.
