Hi Mike, Stephen,
This patch series adds clock 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
2. Make it clear which code supports ES1.x, so it can easily be
identified and removed later, when production SoCs are deemed
This is achieved by:
- Updating the clock tables for the latest revision (ES2.0), but not
removing clocks that only exist on earlier revisions (ES1.x),
- Detecting the SoC revision at runtime using the new
soc_device_match() API, and fixing up the clocks tables to match the
actual SoC revision, by:
- NULLifying core and module clocks of modules that do not exist,
- Reparenting module clocks that have a different parent on ES1.x.
Changes compared to v1:
- Update of various module clocks as per datasheet update,
- Add support for RCLK on R-Car H3 ES2.0.
For testers, this series and its dependencies are available in the
topic/r8a7795es2-clk-v2 branch of my renesas-drivers git repository at
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
I plan to queue this up in clk-renesas-for-v4.12.
Thanks for your comments!
