| * power: zynqmp: Add power domain driver for ZynqMPMichal Simek2022-02-151-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Driver should be enabled by CONFIG_POWER_DOMAIN=y and CONFIG_ZYNQMP_POWER_DOMAIN=y. Power domain driver doesn't have own DT node but it uses zynqmp firmware DT node that's why there is a need to bind driver when firmware node is found. Driver itself is simple. It is sending pmufw config object overlay for enabling access to device which is done in ...domain_request(). In ...domain_on() capabilities are passed and node is requested. This should be bare minimum of required to get power domain driver working.

* | env: Allow U-Boot scripts to be placed in a .env fileSimon Glass2021-11-161-0/+7
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At present U-Boot environment variables, and thus scripts, are defined by CONFIG_EXTRA_ENV_SETTINGS. It is painful to add large amounts of text to this file and dealing with quoting and newlines is harder than it should be. It would be better if we could just type the script into a text file and have it included by U-Boot. Add a feature that brings in a .env file associated with the board config, if present. To use it, create a file in a board/<vendor> directory, typically called <board>.env and controlled by the CONFIG_ENV_SOURCE_FILE option. The environment variables should be of the form "var=value". Values can extend to multiple lines. See the README under 'Environment Variables:' for more information and an example. In many cases environment variables need access to the U-Boot CONFIG variables to select different options. Enable this so that the environment scripts can be as useful as the ones currently in the board config files. This uses the C preprocessor, means that comments can be included in the environment using /* ... */ Also support += to allow variables to be appended to. This is needed when using the preprocessor.

* remoteproc: pru: Add support for various PRU cores on K3 AM65x SoCsKeerthy2021-07-151-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The K3 AM65x family of SoCs have the next generation of the PRU-ICSS processor subsystem, commonly referred to as ICSSG. Each ICSSG processor subsystem on AM65x SR1.0 contains two primary PRU cores and two new auxiliary PRU cores called RTUs. The AM65x SR2.0 SoCs have a revised ICSSG IP that is based off the subsequent IP revision used on J721E SoCs. This IP instance has two new custom auxiliary PRU cores called Transmit PRUs (Tx_PRUs) in addition to the existing PRUs and RTUs. Each RTU and Tx_PRU cores have their own dedicated IRAM (smaller than a PRU), Control and debug feature sets, but is different in terms of sub-modules integrated around it and does not have the full capabilities associated with a PRU core. The RTU core is typically used to aid a PRU core in accelerating data transfers, while the Tx_PRU cores is normally used to control the TX L2 FIFO if enabled in Ethernet applications. Both can also be used to run independent applications. The RTU and Tx_PRU cores though share the same Data RAMs as the PRU cores, so the memories have to be partitioned carefully between different applications. The new cores also support a new sub-module called Task Manager to support two different context thread executions.
