[v3,00/11] firmware/soc: ti_sci, ringacc/inta: Preparation for AM64 DMA support

Hi,

Changes since v2:
- silence checkpatch CHECK for alignment by going over 80 chars in patch 10

Changes since v1:
- Use AM64X as family name in patch 11
- Added Reviewed-by tag from Grygorii for patch 6-10

The series prepares the ti_sci, ringacc, inta to support the new DMAs introduced
with AM64.

Separate series has been sent for the inta irqchip driver (v2):
https://lore.kernel.org/lkml/[e-mail]/

Patches for the DMA support will be based on this series due to build and
feature dependencies.

To support the new DMSS we need to change the ti_sci ring config API in order to
be able to support the new parameters needed in the future.

We also need to add support for the second range in RM as along with the AM64
support, the resource allocation is going to change for existing SoC which used
only the first range for resource allocation.

The tx_tdtype support has been also missing from ti_sci for a long time and
the AM64 specific extended_ch_type depends on the existence of it in the message
struct.

Santosh: if you plan to take this series for 5.11, then can you create an
immutable branch which I can refer to Vinod for the DMA patches I'm going to
send soon.

Regards,
Peter
