Hi,

While doing a SoC only build for DRA7, a few bugs did pop up. The
following series provides necessary fixups for the same.

DRA7 does use OPP, uses OMAP interconnect and also does require SCU.
These are missing in the SoC only build of DRA7 breaking various PM
features in DRA7 only build.

#1221725 — [PATCH 2/4] ARM: omap2+: board-generic: Remove stale of_irq macros

FromNishanth Menon <nm@ti.com>

Subject[PATCH 2/4] ARM: omap2+: board-generic: Remove stale of_irq macros
Message-ID<q6UWD-6st-25@gated-at.bofh.it>
In reply to#1221719
When commit c4082d499fa2 ("ARM: omap2+: board-generic: clean up the
irq data from board file") cleaned up the direct usage of gic_of_init
and omap_intc_of_init, it failed to clean up the macros properly.

Since these macros are no longer used, lets just remove them.

OMAP5 SoC has Cortex-A15 which does not use TWD timer. It uses
ARCH_TIMER instead, clean up unwanted configuration and enable
OMAP_INTERCONNECT and OPP which is necessary for expected functionality
on the SoC.

OMAP5 and DRA7 reuse the same pm44xx_erratum variable so, enable the
same, else PM features such as Suspend to ram is broken in a SoC only
build configuration.
