[PATCH v2 00/22] Cleanup and Refactor TI-SCI driver

[Beleswar Padhi]

This series does a lot of cleanups and refactoring of the TI-SCI driver.

Patches 01-11:
The first part of the series refactors a lot of common code from each of
the TI-SCI message functions into a single place (get_one_xfer() and
do_xfer()). Result is removal of net ~740 lines (~20% of the whole driver
size) without changing functionality.

Patches 12-15:
The second part of the series does some preparatory work for being able
to break down the single large TI-SCI file into smaller files.

Patches 16-22:
The third and final part of the series breaks down the single large
ti_sci.c file into smaller logical files: ti_sci core, device, clock,
pm, rm, and proc. This allows for better readability and maintenance.

Note:
Since the [PATCH 10/22] (first part of the cleanup) now passes local
stack values as part of request, the following[0] patch series
in the underlying mbox layer is ideally needed. It is better for those
patches to be picked to avoid any KASAN warnings and possible duplicate
message resends.

v2: Changelog:
1. Fix build for arm32 platforms like keystone by including appropriate
headers in ti_sci_rm.c in [PATCH v2 21/22]. 

Link to v1:
https://lore.kernel.org/all/20260929201746.4078803-1-b-padhi@xxxxxx/

Testing Done:
 - Boot tested on all TI K3 SoCs.
 - Boot tested on Keystone platforms like K2G-EVM, K2G-ICE, K2HK-EVM.
 - Tested some of the Core, Device, Clock, and Proc ops with remoteproc
 - Tested each patch for no new warnings or errors.
