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!

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.
