Hi,
The Renesas RZ/G3S SoC has 6 serial interfaces. One of them is used
as debug console (and it is already enabled in the current code base).
Series adds support for the remaining ones.
Patches:
- 01/08 - adds clock, reset and power domain support for the serial
interfaces
- 02/08 - serial driver fix patch identified while adding RZ/G3S
support
- 03/08 - extends suspend to RAM support on the serial driver for
the RZ/G3S SoC
- 04-08/08 - add device tree support
Merge strategy, if any:
- patch 01/08 can go through Renesas tree
- patches 02-03/08 can go through serial tree
- patches 04-08/08 can go through Renesas tree
Thank you,
Claudiu Beznea
Changes in v3:
- in patch "serial: sh-sci: Check if TX data was written to device in
.tx_empty()":
-- check the status of the DMA transaction in tx_empty()
-- changed the variable name that tracks if TX occurred
Changes in v2:
- drop patch "serial: sh-sci: Clean sci_ports[0] after at earlycon exit"
from v1 as it was already applied
- used bool instead of atomic_t in patch
"serial: sh-sci: Check if TX data was written to device in .tx_empty()"
