Hi Santosh,

as you have asked I have sending the ringacc driver as a separate series from
the DMA support for K3 platform.

I have picked the patches from v8 of the DMA support series.

The changelog regarding to ringacc:

Changes since v8:
- No change, picked from
 v8: https://lore.kernel.org/lkml/20191223110458.30766-1-peter.ujfalusi@ti.com/

Changes since v7:
- Added Tested-by from Keerthy
- Do not allow it to be built as a module for now as two exports are missing
  from kernel:
 - devm_ti_sci_get_of_resource()
 - of_msi_get_domain()

Changes since v6:
- No change

Changes since v5:
- No change

Changes since v4:
- clarify the meaning of ti,sci-dev-id in the binding document
- Remove 'default y' from Kconfig
- Fix struct comments
- Move try_module_get() earlier in k3_ringacc_request_ring()

Changes since v3:
- TODO_GS is removed from the header
- pm_runtime removed as NAVSS and it's components are always on
- Check validity of Message mode setup (element size > 8 bytes must use proxy)

Changes since v2:
- fixed up th commit message (SoB, TI-SCI)
- fixed ring reset
- CONFIG_TI_K3_RINGACC_DEBUG is removed along with the dbg_write/read functions
  and use dev_dbg()
- k3_ringacc_ring_dump() is moved to static
- step numbering removed from k3_ringacc_ring_reset_dma()
- Add clarification comment for shared ring usage in k3_ringacc_ring_cfg()
- Magic shift values in k3_ringacc_ring_cfg_proxy() got defined
- K3_RINGACC_RING_MODE_QM is removed as it is not supported

Changes since v1:
