Hi all,
This RFC patch series reworks the Kconfig and Makefile logic for the
Renesas clock and SoC drivers. It was sparked by a discussion with Olof
about the Renesas clock driver dependencies.
The goals are to:
- Allow precise control over and automatic selection of which
(sub)drivers are used for which SoC (which may change in the
future),
- Allow adding support for new SoCs easily,
- Allow compile-testing of all (sub)drivers,
- Keep driver selection logic in the subsystem-specific Kconfig
independent from the architecture-specific Kconfig (i.e. no "select"
from arch/arm64/Kconfig.platforms), to avoid dependencies.
The series can't be applied as-is, because compile-testing all drivers
depends on independent fixes, some in other subsystems.
More details are provided in the individual patch descriptions.
For testing, this patch series, plus several fixes to allow more
compile-testing, are available in the
topic/clk-soc-renesas-Kconfig-rework branch of my renesas-drivers git
repository at
git://git.kernel.org/pub/scm/linux/kernel/git/geert/renesas-drivers.git.
This has been tested on R-Car Gen2 and Gen3, and compile-tested for
various other configurations.
Thanks for your comments!
