Hi all,
This patch series adds initial support for the Renesas R-Car M3-W+
(R8A77961) SoC, and for the Salvator-XS development board equipped with
this SoC. As R-Car M3-W+ is very similar to R-Car M3-W (R8A77960), the
existing RST and SYSC drivers are updated to handle both.
To avoid confusion between R-Car M3-W and M3-W+, a new config symbol
(ARCH_R8A77960) is introduced for M3-W, to replace the old symbol
(ARCH_R8A7796) later. The old symbol will be removed when all users in
other subsystems have been converted to use the new symbol.
The existing config symbol for M3-W SYSC is renamed to SYSC_R8A77960.
Changes compared to v1[1]:
- Split in per-subsystem series,
- Add Reviewed-by, Tested-by,
- Rename SYSC_R8A7796,
- Add ARCH_R8A77960,
- Prepare for future removal of ARCH_R8A7796,
- Wrap SoC-specific parts in #ifdefs.
I intend to queue this series in renesas-devel for v5.5 (except for the
local defconfig patch).
Note that arch/arm64/boot/dts/renesas/r8a77961.dtsi depends on the power
domain and clock domain indices from:
- "[PATCH v2 5/5] dt-bindings: power: Add r8a77961 SYSC power domain
definitions"[2],
- "[PATCH v2 2/4] dt-bindings: clock: Add r8a77961 CPG Core Clock
Definitions"[3],
which will be put on a branch shared by drivers and DTS.
For testing, I pushed this and all dependencies[2-5] to the
topic/r8a77961-v2 branch of my renesas-drivers git repository at
git://git.kernel.org/pub/scm/linux/kernel/git/geert/renesas-drivers.git.
Thanks for your comments!
