Hello.
Here's the set of 12 patches against Simon Horman's 'renesas.git' repo,
'renesas-devel-20160606-v4.7-rc2' tag. We add the device tree support for
the R8A7792-based Blanche board. Added in this version is the SMP support.
The R-Car 'clk' driver patch was posted separately and 2 'clk' binding patches
were split from this series...
[01/12] ARM: shmobile: r8a7792: add clock index macros
[02/12] ARM: shmobile: r8a7792: add power domain index macros
[03/12] soc: renesas: rcar-sysc: add R8A7792 support
[04/12] ARM: shmobile: r8a7792: basic SoC support
[05/12] ARM: shmobile: r8a7792: add SMP support
[06/12] ARM: dts: r8a7792: initial SoC device tree
[07/12] ARM: dts: r8a7792: add SYS-DMAC support
[08/12] ARM: dts: r8a7792: add [H]SCIF support
[09/12] ARM dts: r8a7792: add IRQC support
[10/12] DT: arm: shmobile: document Blanche board
[11/12] ARM: dts: blanche: initial device tree
[12/12] ARM: dts: blanche: add Ethernet support
WBR, Sergei

Add macros usable by the device tree sources to reference the R8A7792
clocks by index.
Signed-off-by: Sergei Shtylyov <sergei.shtylyov@cogentembedded.com>

Changes in version 2:
- removed the SDH, SD0, and SD1 clocks;
- added RCAN and ADSP clock indeces;
- fixed SYS-DMAC0/1 clock indeces.

For new SMP support, you should no longer add an SoC-specific struct
smp_operations, but rely on the DT "enable-method" property, cfr.
"[PATCH v3 00/09] ARM: shmobile: APMU DT support via SMP Enable method V3"
(http://www.spinics.net/lists/linux-sh/msg45229.html).
That series will no longer apply, but I've been carrying (and rebasing) it in
my local tree for quite a while, as it was related to SYSC cleanup (avoiding
your r8a7792_ca15_scu). But unfortunately that depends on the SYSC node always
be present in DT.

My patch is not against you repo, it's against Simon's repo. If you indeed
care for these Magnus' patches (abandoned again?), please re-post them and get
them merged.

My patch is not against you repo, it's against Simon's repo. If you indeed
care for these Magnus' patches (abandoned again?), please re-post them and get
them merged.

The initial R8A7792 SoC device tree including CPU cores, GIC, timer, SYSC,
and the required clock descriptions.

Changes in version 3:
- moved the fixed factor clocks under the "soc" node;
- added back the CPU1 node, adjusted the changelog.
Changes in version 2:
- explicitly included the IRQ header;
- removed the CPU1 node;
- removed the audio and PCIe bus clocks;
- removed the SDH, SD0, and SD1 CPG clocks;
- added RCAN and ADSP CPG clocks;
- removed the PLL1/2, Z2, ZS, I, B, P, CL, M2, RCLK, OSCCLK, ZB3, ZB3D2, DDR,
and MP fixed factor clocks;
- fixed up the parent and divisor for the CP fixed factor clock;
- swapped the SYS-DMAC0/1 clocks;
- removed all gated clocks except the [H]SCIF, IRQC, and SYS-DMAC ones;
- created the "soc" subnode, moving the SoC device nodes there;
- removed the "clocks" node, moving its fixed clock subnodes to the root and
the MSTP subnodes into the "soc" node.

Changes in version 3:
- refreshed the patch.
Changes in version 2:
- resolved reject, indenting the device nodes that are now under the "soc" node;
- added Simon's ACK and Geert's tag too.

R8A7792 SoC doesn't have the EtherMAC core, so SMSC LAN89218 Ethernet
chip was used instead on the Blanche board; this chip is compatible with
SMSC LAN9115 for which there's a (device tree aware) driver. Describe
the chip in the Blanche device tree; enable DHCP and NFS root in the
kernel command line for the kernel booting.

R8A7792 SoC doesn't have the EtherMAC core, so SMSC LAN89218 Ethernet
chip was used instead on the Blanche board; this chip is compatible with
SMSC LAN9115 for which there's a (device tree aware) driver. Describe
the chip in the Blanche device tree; enable DHCP and NFS root in the
kernel command line for the kernel booting.
