This patch moves shirq interrupt controllers driver and header file out of
plat-spear directory. It is moved to drivers/irqchip/ directory.

ARM: SPEAr3xx: shirq: simplify and move the shared irq multiplexor to DT2012-11-26T11:25:32+00:00Shiraz Hashimshiraz.hashim@st.com2012-08-03T10:03:10+00:00urn:sha1:80515a5a2e3c35e2994105f19af27650e8a16c51
SPEAr3xx architecture includes shared/multiplexed irqs for certain set
of devices. The multiplexor provides a single interrupt to parent
interrupt controller (VIC) on behalf of a group of devices.
There can be multiple groups available on SPEAr3xx variants but not
exceeding 4. The number of devices in a group can differ, further they
may share same set of status/mask registers spanning across different
bit masks. Also in some cases the group may not have enable or other
registers. This makes software little complex.
Present implementation was non-DT and had few complex data structures to
decipher banks, number of irqs supported, mask and registers involved.
This patch simplifies the overall design and convert it in to DT. It
also removes all registration from individual SoC files and bring them
in to common shirq.c.
Also updated the corresponding documentation for DT binding of shirq.

ARM: 6091/1: ST SPEAr: Adding support for shared irq layer2010-05-04T15:54:54+00:00viresh kumarviresh.kumar@st.com2010-05-03T08:24:30+00:00urn:sha1:4c18e77f718cdda33363132127db4df795eadbd9
Multiple peripherals in SPEAr share common hardware interrupt lines.
This patch adds support for a shared irq layer, which registers hardware
irqs by itself and exposes virtual irq numbers to peripherals.
