Subject: [PATCH 0/3][V4] iio: imu: Add support for the ADIS16460 IMU
Date: Tue, 23 Jul 2019 10:36:37 +0300 [thread overview]
Message-ID: <20190723073641.27801-1-alexandru.ardelean@analog.com> (raw)
This changeset adds support for the ADIS16460.
The default CS change delay is 10 uS, while the ADIS16460 requires a
minimum of 16 uS.
As it turns out, the SPI framework support already has support for this
feature, which is currently present in the for-next branch:
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi.git/commit/?h=0ff2de8bb163551ec4230a5a6f3c40c1f6adec4f
This changeset now makes use of that feature, to allow longer CS change
times (as needed) for ADIS16460.
The SPI patch is present in the iio/testing branch, but not present in the
iio/togreg branch.
Changelog v3 -> v4:
* for SPI: no change
* for ADIS lib: use existing `cs_change_delay` feature (from SPI)
* for DT: no change
Changelog v2 -> v3:
* for SPI:
* used `cs_change_delay` instead of `cs_change_delay_usecs` (i.e. removed
`_usecs` suffix
* used SPI specific subject line for SPI patch
* for ADIS lib:
* updated to use the `cs_change_delay`
* for DT:
* added Rob's `Reviewed-by` tag
Changelog v1 -> v2:
* for SPI:
* renamed `cs_change_stall_delay_us` -> `cs_change_delay_usecs`
initial recommendation was `cs_change_delay`, but decided to name this
`cs_change_delay_usecs`, since the convention for these delays seems
to add the `_usecs` suffix
* for ADIS lib:
* renamed `stall_delay` -> `cs_change_delay`
* removed some assignments of `cs_change_delay`
where `cs_change` is not set
* for ADIS16460 driver:
* fixed license
* adjusted to new `cs_change_delay[_usecs]`
