Hi Simon, Magnus,
This patch series adds power domain support for R-Car H3 ES2.0, which
differs from ES1.x in some 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 detecting the SoC revision at runtime using the
soc_device_match() API, and fixing up the power area table to match the
actual SoC revision.
Changes compared to v1:
- Minor changes to the patch descriptions.
As PM Domains are initialized quite early, the Renesas SoC device must
be initialized earlier, and this series thus depends on the pull
request "[git pull] base: soc: Improvements for the SoC bus and
soc_device_match()" I've just sent.
For testers, this series and its dependencies are available in the
topic/r8a7795es2-sysc-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.
Thanks for applying!
