This patch adds single bitmap register support to intc. The current code only handles 16 and 32 bit registers where a set bit means interrupt enabled, but this is easy to extend in the future. The INTC_IRQ() macro is also added to provide a way to hook in interrupt controllers for FPGAs in boards or companion chips.

This patch removes redundant interrupt code for the shmin board which is using a sh770x processor and 4 IRQ lines as individual interrupts (IRQ-mode). Signed-off-by: NMagnus Damm <damm@igel.co.jp> Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

This patch removes redundant board specific interrupt code for boards using sh775x processors and 4 IRQ lines in "Individual Interrupt Mode" aka IRLM. Three boards are affected: sh03, snapgear and titan. The right way to do this is to use cpu specific code provided by intc. A nice side effect is that sh03 now compiles, board not BROKEN any more.

All SH-4 parts have a 4-digit year, while the SH-3 parts typically only use a 2-digit one. The SH7705, SH7710, and SH7712 SH-3 parts however opted to extend it to 4-digit and still look and act like an SH-3 RTC in all other ways. This adds a capability flag (RTC_CAP_4_DIGIT_YEAR) that these corner-case CPU subtypes can set in their platform data and cleans up some of the ifdef mess in the driver as a result.

This patch converts the cpu specific interrupt setup code for sh7760 from ipr + intc2 to intc. New vectors are also added to match the information provided by the datasheet. Vectors for IRQ4-IRQ7 are enabled by default. Use plat_irq_setup_pins() if pins IRL0-3 should be used in IRLM mode. The patch also adds the SIM block to the serial port platform data.

This patch unifies the cpu specific interrupt setup code for sh7706, sh7707, sh7708 and sh7709 and moves the code into a new file called setup-sh770x.c. It makes sense to share the setup code between these processors because most hardware blocks are identical from a software point of view. With this patch the sh770x processors now have a complete set of vectors that match with the information provided by the data sheets. This is a big improvement for sh7708. Vectors for IRQ4 and IRQ5 are enabled by default. Use plat_irq_setup_pins() if pins IRQ0-3 should be used in IRQ mode. This patch also unifies the platform device setup code which means that the rtc driver now has platform data for all sh770x processors.

Now that __initmv references the machvec section unconditionally there have been cases where folks have been mistakenly flagging non-machvec structures with the machvec section attribute (presumably to shut up modpost). This leads to obscure breakage in earlyprintk amongst other places and is rather non-obvious. Add a simple sanity check to try and catch __initmv misuse and panic early.

In the SH-3/4 TLB access violation path we were enabling IRQs before the call in to trace_hardirqs_on(), which ended up triggering: if (DEBUG_LOCKS_WARN_ON(!irqs_disabled())) return; in kernel/lockdep.c:2031. Fix this up by removing the early re-enable, we were already re-enabling IRQs post-trace_hardirqs_on() already, so the semantics are now as was initially intended.

We need to make sure, that the clockevent devices are resumed, before the tick is resumed. The current resume logic does not guarantee this. Add CLOCK_EVT_MODE_RESUME and call the set mode functions of the clock event devices before resuming the tick / oneshot functionality. Fixup the existing users.

This patch converts the cpu specific 7750 setup code to use the new intc controller. Many new vectors are added and multiple processor variants including 7091, 7750, 7750s, 7750r, 7751 and 7751r should all have the correct vectors hooked up.

This gets the SH cpufreq working again. We follow the changes in the AVR32 implementation for wrapping in to the clock framework. CPUs that wish to use this are required to define rate rounding primitives in order to satisfy clk_round_rate(). This works well enough for the common case, though we should look at unifying this driver across all of the platforms that implement clock framework support in one capacity or another.

This patch converts the cpu specific 7780 setup code to use the new intc controller. Many new vectors are added and also support for external interrupt sense configuration. So with this patch it is now possible to configure external interrupt pins as edge or level triggered using set_irq_type(). No external interrupts are registered by default. Use plat_irq_setup_pins() to select between IRQ or IRL mode. This patch also fixes the Alarm IRQ for the RTC.

This patch improves intc group support, ie it makes it possible to group interrupts together and mask / unmask the entire group. This also works with priorities, so setting a priority for an entire group is also possible. This patch is needed to properly support certain processors such as the 7780.
