Add device nodes for the two DDR Bus State Controllers (DBSC). The DBSCs are located in the A3BC PM domain, which must not be powered down, else the system will crash. A reference to the A3BC PM domain will be added later. Signed-off-by:

Add DT bindings for Renesas R-Mobile and SH-Mobile memory controllers. Currently memory controller device nodes are used only to reference PM domains, and prevent these PM domains from being powered down, which would crash the system. Signed-off-by:

I made a mistake when rebasing Andrey Gusakov's patch adding MLB+ clock to the R8A7791 device tree, inserting <&hp_clk> into the "clocks" property of the MSTP8 node at a wrong position, so that the input clocks for MLB+ and IPMMU-SGX got swapped... Fixes: 7408d306 ("ARM: shmobile: r8a7791: add MLB+ clock") Signed-off-by:

Add a device node for the System Controller, with subnodes that represent the hardware power area hierarchy. Hook up all devices to their respective PM domains. Add a minimal device node for the Coresight-ETM hardware block, and hook it up to the D4 PM domain, so the R-Mobile System Controller driver can keep the domain powered, until the new Coresight code handles runtime PM.

The Renesas R-Mobile System Controller provides a.o. power management support, following the generic PM domain bindings in Documentation/devicetree/bindings/power/power_domain.txt. For now this supports the R-Mobile A1 (r8a7740) only, but it should be sufficiently generic to handle other members of the SH-Mobile/R-Mobile family in the future. Signed-off-by:

The FSI2 sound node used the generic compatible property only. Add the SoC-specific one, to make it future proof. Signed-off-by:

Pull ACCESS_ONCE cleanup preparation from Christian Borntraeger: "kernel: Provide READ_ONCE and ASSIGN_ONCE As discussed on LKML http://marc.info/?i=54611D86.4040306%40de.ibm.com ACCESS_ONCE might fail with specific compilers for non-scalar accesses. Here is a set of patches to tackle that problem. The first patch introduce READ_ONCE and ASSIGN_ONCE. If the data structure is larger than the machine word size memcpy is used and a warning is emitted. The next patches fix up several in-tree users of ACCESS_ONCE on non-scalar types. This does not yet contain a patch that forces ACCESS_ONCE to work only on scalar types. This is targetted for the next merge window as Linux next already contains new offenders regarding ACCESS_ONCE vs. non-scalar types" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/borntraeger/linux: s390/kvm: REPLACE barrier fixup with READ_ONCE arm/spinlock: Replace ACCESS_ONCE with READ_ONCE arm64/spinlock: Replace ACCESS_ONCE READ_ONCE mips/gup: Replace ACCESS_ONCE with READ_ONCE x86/gup: Replace ACCESS_ONCE with READ_ONCE x86/spinlock: Replace ACCESS_ONCE with READ_ONCE mm: replace ACCESS_ONCE with READ_ONCE or barriers kernel: Provide READ_ONCE and ASSIGN_ONCE
