Hi all,
This patch series adds GPIO support for the Renesas R-Car S4-8 Soc.
It is marked as an RFC because of 2 reasons:
1. GPIO register banks 4-7 are disabled, as they do not seem to be
accessible as-is using either the Control Domain (0xffd9....) or
Application Domain (0xdfd9....) addresses.
How to make the Control Domain release the bus guard, so the
registers become accessible?
2. This has been boot-tested, without using any actual GPIOs.
For testing, this series and its dependencies can be found at[1].
Thanks for your comments!
