Hi Simon, Magnus, This patch series enables DT support for PM domains on the Renesas SH-Mobile AG5 (sh73a0) SoC. This series builds further on the DT PM Domain support for R-Mobile A1 (r8a7740). Due to the similarity of the SYSC System-Controller on the various SH-Mobile/R-Mobile SoCs, and the abstraction of PM domains in DT, the same driver can handle sh73a0 after some small modifications, without changing the DT bindings. Compared to r8a7740, the only significant change is the move of the memory-controller(s) to separate PM domains on sh73a0 (and also on R-Mobile APE6 (r8a73a4)). Hence a provision must be made to not turn off these PM domains inadvertently, cfr. the series "[PATCH 0/4] ARM: shmobile: Add DT support for memory controllers" I've just sent. This series has been sent before, as part of the series "[PATCH RFC 0/7] ARM: shmobile: sh73a0: DT PM domain support" (https://lkml.org/lkml/2014/11/19/404). Changes since v1 (more detailed changelogs in the individual patches): - Factored out addition of the memory-controller in a separate series. Dependencies: 1. Patches 1-4 (DT binding doc, C code) depend on: a. The R-Mobile DT PM Domain work for r8a7740, queued in tag renesas-dt-pm-for-v3.20 of Simon's repository, b. "ARM: shmobile: R-Mobile: Fix DT refcount bugs in PM domain code" (http://www.spinics.net/lists/arm-kernel/msg391084.html), 2. Patch 5 (dtsi) depends on: a. The multiplatform work for sh73a0, queued in branch sh73a0-multiplatform-for-v3.20 of Simon's repository, b. Series "[PATCH 0/4] ARM: shmobile: Add DT support for memory controllers" (http://marc.info/?l=linux-sh&m=142123399414888). 3. Patch 6 (drivers/sh) depends on all of the above. This was tested on kzm9g-multiplatform. Thanks!
