On LSM6DSO/LSM6DSR/LSM6DSOX/ASM330LHH and ISH330DHCX devices it is possible to trim the hardware timestamp resolution through the FREQ_FINE[7:0] bits of the INTERNAL_FREQ_FINE register, which contains the difference in percentage of the effective ODR (and timestamp rate) with respect to the typical value. The formula for calculating the effective ODR reported in the application notes has been linearized to the first order to simplify the calculation (pls. see note on source code). This change may be useful in the outcome of CTS tests regarding the SingleSensorTests and the SensorTest#testSensorTimeStamps for high ODRs Signed-off-by: Mario Tesi <mario.tesi@st.com> Acked-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
