f12468a6fd sh: Fix OFFCHIP_IRQ_BASE compile error.
HP6xx uses OFFCHIP_IRQ_BASE to know the base irq number where non
cpu interrupts should start. This define was in irq.h before, but
since rework got lost. It really belongs inside hd64461.h since
the hp6xx wont work without it.

897cfcd878 sh: intc - rework higlander irq code for r7780mp and r7785rp
This patch reworks the highlander irq code for r7780mp and r7785rp.
The same strategy as for the new R2D code is used here - the board
specific interrupts are now starting from HL_FPGA_IRQ_BASE. The code
for r7780rp is not touched due to lack of hardware.

Tested with CF, AX88796 on r7780mp and r7785rp. The touch switch
interrupt has also been tested on r7780mp.

This patch contains various intc fixes for problems reported by
Markus Brunner on the linuxsh-dev mailing list:

http://marc.info/?l=linuxsh-dev&m=118701948224991&w=1

Apart from added comments, the fixes are:

- add intc_set_priority() function prototype to hw_irq.h
- fix off-by-one error in intc_set_priority()
- make sure _INTC_WIDTH() is set for primary priority masking

Big thanks to Markus for finding these problems. Version two fixes
a compile error and an inverted primary check.

2eeec85638 sh: intc - convert board specific r2d code
This patch converts the board specific interrupt code for r2d to make
use of intc. While at it we improve the Kconfig to avoid confusion.

- Two sets of interrupt tables exist - one for R2D-1 and one for R2D-PLUS.
- R2D-1 and R2D-PLUS use the same irq constants.
- R2D-1 has AX88796 support, R2D-PLUS does not hook up that IRQ.
- R2D-PLUS has KEY support, R2D-1 does not hook up that IRQ.
- The number and order of IRQ values are disconnected from register bits.
- Interrupt sources now start from IRQ 100.
- The machvec demux function converts from irlm IRQ 0-14 to IRQ 100++.

Tested on R2D-1 and R2D-PLUS boards.

Version 2 adds CONFIG_RTS7751R2D_1 and CONFIG_RTS7751R2D_PLUS together
with intc structured as __initdata.

48180cab3a sh: intc - convert voyagergx code
This patch converts the sh-specific voyagergx interrupt code to make use
of intc. A lot of "interesting" old cruft gets replaced with intc tables
and some simple demux code.

- All interrupt sources in the sm501 data sheet are now in the header.
- The number and order of IRQ values are disconnected from register bits.
- Interrupt sources now start from IRQ 200.
- set_irq_chained_handler() is now used to hook up the demux function.

In the future it would probably make sense to move the interrupt demuxer
into into the mfd driver, but this is probably a nice step in the right
direction until that happens.
