Hi Linus, Laurent,
This patch series adds pinctrl support for R-Car H3 ES2.0, which differs
from ES1.x in several areas.
The goal is twofold:
1. Support both the ES1.x and ES2.0 SoC revisions in a single binary
for now,
2. Make it clear which code supports ES1.x, so it can easily be
identified and removed later, when production SoCs are deemed
ubiquitous.
This is achieved by:
1. Extracting the support for R-Car H3 ES1.x into a separate file, as
the differences are quite large,
2. Adding code for detecting the SoC revision at runtime using the new
soc_device_match() API, and selecting pinctrl tables for the actual
SoC revision,
3. Replacing the core register and bitfield definitions, and pins,
groups, and functions for basic devices by their counterparts for
R-Car H3 ES2.0.
Changes compared to v1:
- Print correct subdriver name,
- Extend Proof-of-Concept to basic support (SCIF serial port).
The addition of pins, groups, and functions for other on-chip devices is
left to subsequent patches.
For testers, this series and its dependencies are available in the
topic/r8a7795es2-pfc-v2 branch of my renesas-drivers git repository at
git://git.kernel.org/pub/scm/linux/kernel/git/geert/renesas-drivers.git.
An integration branch for testing on the R-Car H3 ES2.0 based Salvator-X
development board is provided as topic/r8a7795es2-integration.
This has been tested on Salvator-X with R-Car H3 ES1.0, ES1.1, and ES2.0
SoCs.
I plan to queue this up in sh-pfc-for-v4.12.
Thanks for your comments!
