[PATCH v2 0/9] arm64: dts: renesas: Add support for more R-Car V4H and White Hawk variants

[Geert Uytterhoeven]

	Hi all,

This patch series extends the existing support for the Renesas White
Hawk CPU and Breakout board stack by adding support for:
  1. Standalone use of the White Hawk CPU board,
  2. The White Hawk Single board, which is a single-board integration
     of the Renesas White Hawk CPU and Breakout board stack, based on
     the R-Car V4H ES2.0 (R8A779G2) SoC.

Changes compared to v1[1]:
  - Add Reviewed-by.
  - Split off restoring sort order into its own patch,
  - New patch "[PATCH v2 5/9] arm64: dts: renesas: white-hawk: Add SoC
    name to top-level comment",
  - Rebase on top of commit fc67495680f60e88 ("arm64: dts: renesas:
    white-hawk-cpu: Fix missing serial console pin control",
  - Refer to hscif0_pins directly,
  - Add SoC name to top-level comment.

I plan to queue this in renesas-devel for v6.9.

For testing, this series can be found at
https://git.kernel.org/pub/scm/linux/kernel/git/geert/renesas-drivers.git/log/?h=topic/v4h-white-hawk-more-v2

Thanks for your comments!

[PATCH v2 1/9] dt-bindings: soc: renesas: Document R-Car V4H White Hawk Single

[Geert Uytterhoeven]

Document the compatible values for the Renesas R-Car V4H ES2.0
(R8A779G2) SoC and the Renesas White Hawk Single board.
The former is an updated version of R-Car V4H (R8A779G0).
The latter is a single-board integration of the Renesas White Hawk CPU
and Breakout board stack.

[PATCH v2 2/9] arm64: dts: renesas: r8a779g0: Add standalone White Hawk CPU support

[Geert Uytterhoeven]

The White Hawk CPU board can be used standalone, without connecting it
to the White Hawk BreakOut board.

Add a DTS file for supporting this use case.

[PATCH v2 4/9] arm64: dts: renesas: white-hawk: Drop SoC parts from sub boards

[Geert Uytterhoeven]

The White Hawk CSI/DSI and RAVB/Ethernet(1000Base-T1) sub boards are not
specific to R-Car V4H.

Hence rename their DTS file names to drop the "r8a779g0-" prefix, and
remove any references to R-Car V4H.

[PATCH v2 7/9] arm64: dts: renesas: white-hawk: Factor out common parts

[Geert Uytterhoeven]

Factor out the parts on the White Hawk BreakOut board that are also
present on the White Hawk Single board, so they can be reused when
introducing support for the latter.

[PATCH v2 9/9] arm64: dts: renesas: r8a779g2: Add White Hawk Single support

[Geert Uytterhoeven]

The White Hawk Single board is a single-board integration of the Renesas
White Hawk CPU and Breakout board stack, based on the R-Car V4H ES2.0
(R8A779G2) SoC.

For now, the only visible differences compared to the board stack are:
  - The SoC is an updated version of R-Car V4H (R8A779G0),
  - The serial console uses an FT2232H instead of a CP2102 USB-UART
    bridge, with CTS/RTS wired.
