[PATCH v2 0/2] arm64: renesas: Add R-Car S4-8 Pin control support

[Geert Uytterhoeven]

	Hi all,

This patch series adds pin control support for the Renesas R-Car S4-8
Soc on the Spider board, and enables pin control for the serial console.

Changes compared to v1[1]:
  - Drop register banks 4-7, as they can only be accessed from the
    Control Domain.

Serial console and I2C[2] have been tested on the Renesas Spider
development board.

Thanks for your comments!

[PATCH v2 1/2] arm64: dts: renesas: r8a779f0: Add pinctrl device node

[Geert Uytterhoeven]

Add a device node for the Pin Function Controller on the Renesas R-Car
S4-8 (R8A779F0) SoC.

Note that the register block does not include registers for banks 4-7,
as they can only be accessed from the Control Domain.
