Texas Instrument's System Control Interface (TI-SCI) Message Protocol
is used in Texas Instrument's System on Chip (SoC) such as those
in K3 family AM654 SoC to communicate between various compute
processors with a central system controller entity.

The system controller provides various services including the control
of other compute processors within the SoC. Extend the TI-SCI protocol
support to add various TI-SCI commands to invoke services associated
with power and reset control, and boot vector management of the
various compute processors from the Linux kernel.

Hi Santosh, Nishanth, Tero,

Appreciate it if this patch can be picked up for the 5.3 merge window.
This is a dependency patch for my various remoteproc drivers on TI K3
SoCs. Patch is on top of v5.2-rc1.

I will pick this up for 5.3.


There is a pile of drivers/firmware changes for ti-sci, which have cross dependencies, and will cause merge conflicts also as they touch same file.

Do you mind if I setup a pull-request for these all and send it to you? They are going to be on top of the keystone clock pull-request I just sent today though, otherwise it won't compile (the 32bit clock support has dependency towards the clock driver.)

That will be great Tero.

Ok doing that.

For this patch, queuing up for 5.3, thanks.
