a864446f96 ARM: dts: r8a7794: Add BRG support for (H)SCIF 
Add the device node for the external SCIF_CLK.
The presence of the SCIF_CLK crystal and its clock frequency depends on
the actual board.

Add the two optional clock sources (ZS_CLK and SCIF_CLK for the internal
resp. external clock) for the Baud Rate Generator for External Clock
(BRG) to all SCIF and HSCIF device nodes.

This increases the range and accuracy of supported baud rates on
(H)SCIF.

0a3d058b8a ARM: shmobile: r8a7794: Use SoC specific binding for rcar-dmac nodes 
Use the new SoC specific binding for rcar-dmac and the generic
binding as a fall-back in the r8a7794 device tree.

In general Renesas hardware is not documented to the extent where the
relationship between IP blocks on different SoCs can be assumed although
they may appear to operate the same way. Furthermore the documentation
typically does not specify a version for individual IP blocks. For these
reasons a convention of using the SoC name in place of a version and
providing SoC-specific compat strings has been adopted.

Although not universally liked this convention is used in the bindings for
most drivers for Renesas hardware. The purpose of this patch is to
update the Renesas R-Car DMA Controller nodes to follow this convention.

Replace the "arm,cortex-a15-gic" compatible value for the GIC by
"arm,gic-400", as the R-Car Gen2 GIC is assumed to be a GIC-400.
This has been confirmed by reading the GICD_IIDR register (on r8a7791),
which reports 0x0200043b (GIC-400 = 0x02, ARM = 0x43b).

This has no effect on runtime behavior, as currently the GIC driver
treats both compatible values the same.
