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.
It is based on patches in the BSP by LUU HOAI, with many changes on top
(see the individual patches).
This series is marked as an RFC because of 2 reasons:
1. PFC register banks 4-7 do not seem to be accessible as-is using
either the Control Domain (0xffd9....) or Application Domain
(0xdfd9....) addresses, so currently you cannot configure pins
controlled by these banks.
How to make the Control Domain release the bus guard, so the
registers become accessible?
2. It this has been tested only lightly with remote access.
For testing, this series and its dependencies can be found at[1].
Thanks for your comments!
