remoteproc: ipu: Add driver to bring up ipu

2022-02-08T16:00:03Z

The driver enables IPU support. Basically enables the clocks, timers, watchdog timers and bare minimal MMU and supports loading the firmware from mmc. Signed-off-by: Keerthy [Amjad: fix compile warnings] Signed-off-by: Amjad Ouled-Ameur

remoteproc: uclass: Add remoteproc resource handling helpers

2022-02-08T16:00:03Z

Add remoteproc resource handling helpers. These functions are primarily to parse the resource table and to handle different types of resources. Carveout, devmem, trace & vring resources are handled.

remoteproc: k3_system_controller: Support optional boot_notification channel

2022-02-08T14:41:26Z

If there is an optional boot notification channel that an SoC uses separate from the rx path, use the same. Signed-off-by: Nishanth Menon

remoteproc: pru: Add support for various PRU cores on K3 AM65x SoCs

2021-07-15T12:26:04Z

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.

remoteproc: k3-r5: remove sysfw PM calls if not supported

2021-06-11T11:04:52Z

With the sysfw rearch, sysfw PM calls are no longer available from SPL level. To properly support this, remove the is_on checks and the reset assertion from the R5 remoteproc driver as these are not supported. Attempting to access unavailable services will cause the device to hang. Signed-off-by: Tero Kristo Signed-off-by: Tero Kristo

remoteproc: k3_r5: Sync to upstreamed kernel DT property names

2021-02-04T15:07:56Z

The K3 R5F remoteproc driver in U-Boot was upstreamed prior to the equivalent remoteproc driver in the Linux kernel. Some of the DT properties used in U-Boot got upstreamed using different names in Linux kernel. The modified property names include the R5F cluster mode configuration property "lockstep-mode"; and three different individual R5F core config properties - "atcm-enable", "btcm-enable" and "loczrama". The property names were updated as follows: lockstep-mode => ti,cluster-mode atcm-enable => ti,atcm-enable btcm-enable => ti,btcm-enable loczrama => ti,loczrama Update the K3 R5F remoteproc driver, the corresponding binding, and all the existing usage in AM65x, J721E and J7200 dts files all at once to use the new properties and to not break any bisectability.
