Build and Infrastructure
|
|
************************
|
|
|
|
|
|
* Devicetree
|
|
|
|
* Various compatibles had incorrect vendor prefixes in their :ref:`compatible
|
|
<dt-important-props>` properties; the following changes were made to fix
|
|
these.
|
|
|
|
* ``nios,i2c`` is now ``altr,nios2-i2c``
|
|
* ``colorway,lpd8803`` is now ``greeled,lpd8803``
|
|
* ``colorway,lpd8806`` is now ``greeled,lpd8806``
|
|
* ``grove,light`` is now ``seeed,grove-light``
|
|
* ``grove,temperature`` is now ``seeed,grove-temperature``
|
|
* ``max,max30101`` is now ``maxim,max30101``
|
|
* ``ublox,sara-r4`` is now ``u-blox,sara-r4``
|
|
* ``xtensa,core-intc`` is now ``cdns,xtensa-core-intc``
|
|
|
|
Out of tree users of these compatibles will need to update their
|
|
devicetrees.
|
|
|
|
You can support multiple versions of Zephyr with one devicetree by
|
|
including both the old and new values in your nodes' compatible properties,
|
|
like this example for the LPD8803::
|
|
|
|
my-led-strip@0 {
|
|
compatible = "colorway,lpd8803", "greeled,lpd8803";
|
|
...
|
|
};

* CMSIS subsystem
|
|
|
|
|
|
* Power management
|
|
|
|
* The APIs to set/clear/check if devices are busy from a power management
|
|
perspective have been moved to the PM subsystem. Their naming and signature
|
|
has also been adjusted to follow common conventions. Below you can find the
|
|
equivalence list.
|
|
|
|
* ``device_busy_set`` -> ``pm_device_busy_set``
|
|
* ``device_busy_clear`` -> ``pm_device_busy_clear``
|
|
* ``device_busy_check`` -> ``pm_device_is_busy``
|
|
* ``device_any_busy_check`` -> ``pm_device_is_any_busy``
|
|
|
|
* Logging

|
|

HALs

|
* HALs are now moved out of the main tree as external modules and reside in
|
|
their own standalone repositories.
|
|
|
|
|
|
Trusted Firmware-m
|
|
******************
|
|
|
|
* Renamed psa_level_1 sample to psa_crypto. Extended the use of the PSA Cryptography
|
|
1.0 API in the sample code to demonstrate additional crypto functionality.
|
|
* Added a new sample to showcase the PSA Protecter Storage service.
|
|
|
|
Documentation
|
|
*************
|
|
|
|
* Kconfig options need to be referenced using the ``:kconfig:`` Sphinx role.
|
|
Previous to this change, ``:option:`` was used for this purpose.
|
|
* Doxygen alias ``@config{}`` has been deprecated in favor of ``@kconfig{}``.
