[PATCH] arm64: dts: renesas: r8a779a0: Update to R-Car Gen4 compatible values

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Despite the name, R-Car V3U is the first member of the R-Car Gen4
family.  Hence update the compatible properties in various device nodes
to include family-specific compatible values for R-Car Gen4 instead of
R-Car Gen3:
  - DMAC,
  - (H)SCIF,
  - I2C,
  - IPMMU,
  - WDT.

Signed-off-by: Geert Uytterhoeven <geert+renesas@xxxxxxxxx>
---
To be queued in renesas-devel for v5.19.

All R-Car Gen4 family-specific compatible values added are already
supported by device drivers in v5.18-rc1, except for HSCIF, where the
driver matches on the generic "renesas,hscif" compatible value instead.
Hence this patch is safe to apply.
Patches to update the corresponding DT bindings[1] and SoC identication
code[1] are in-flight.

Updating the remaining compatible properties is postponed until the
corresponding DT bindings and device drivers have been updated.
