sh: missing symbol fix for sh4-202

2007-08-22T04:32:07+00:00

This patch adds a plat_irq_setup() symbol for sh4-202. Without
this fix it is impossible to build a working kernel using the
microdev_defconfig.

sh: Fix lockdep debugging oops on SH-3/4.

2007-08-01T07:17:07+00:00

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.

sh: remove old broken pint code

2007-07-25T01:46:32+00:00

The code in arch/sh/kernel/cpu/irq/pint.c doesn't compile, so let's
get rid of it to make space for a future pint implementation on top
of intc.

sh: intc - add support for SH7750 and its variants

2007-07-20T09:44:49+00:00

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.

IRLM interrupts can be enabled using ipr_irq_enable_irlm() which
now is marked as __init.

sh: Support rate rounding for SH7722 FRQCR clocks.

2007-07-20T04:30:07+00:00

Now that the round_rate() op is supported, hook it up on SH7722
for the FRQCR (CPU, PCLK, etc.) clocks.

sh: Implement clk_round_rate() in the clock framework.

2007-07-20T04:29:09+00:00

This is an optional component of the clock framework. However,
as we're going to be using this in the cpufreq drivers, add
support for it to the framework.

sh: intc - add support for 7780

2007-07-20T03:18:21+00:00

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.
