Hi all,
This patch series adds the R-Car System Controller to the DTS files for
the various R-Car SoCs, and hooks up devices to their respective PM
domains.
This is a dependency for the enablement of DU and VSP on R-Car H3, as
the VSPs are located in a PM Domain.
Changes compared to v2:
- Move power area hierarchy from DT to C (cfr. DT bindings for Renesas
CPG/MSSR), and switch to "#power-domain-cells = <1>",
- Drop fallback compatibility strings, as the bindings are
SoC-specific,
- Add an "always-on" power area on R-Car H3.
Changes compared to v1:
- Add R-Car H3 (r8a7795) support,
- Use "renesas,<type>-sysc" instead of "renesas,sysc-<type>",
- Add fallback compatibility strings for R-Car Gen2 and Gen3.
Dependencies:
- renesas-devel-20160307-v4.5-rc7,
- clk/clk-next with "[PATCH v2] clk: renesas: Rename header file
renesas.h" applied,
- "[PATCH 0/4] clk: renesas: PM Domain Cleanups and Preparation".
- "[PATCH v3 0/7] PM / Domains: Add DT bindings for the R-Car System
Controller",
- "[PATCH v3 00/11] soc: renesas: Add R-Car SYSC PM Domain Support".
Note that these are hard dependencies: adding SYSC PM Domains to DTS
files without driver support cause breakage!
For your convenience, I've pushed this, incl. all dependencies, to the
topic/rcar-sysc-pd-v3 branch of
https://git.kernel.org/cgit/linux/kernel/git/geert/renesas-drivers.git
Thanks for your comments!
