irqdomain: Use irq_domain_get_of_node() instead of direct field access

2015-10-13T17:01:23+00:00

The struct irq_domain contains a "struct device_node *" field (of_node) that is almost the only link between the irqdomain and the device tree infrastructure. In order to prepare for the removal of that field, convert all users to use irq_domain_get_of_node() instead.

genirq: Remove irq argument from irq flow handlers

2015-09-16T13:47:51+00:00

Most interrupt flow handlers do not use the irq argument. Those few which use it can retrieve the irq number from the irq descriptor. Remove the argument. Search and replace was done with coccinelle and some extra helper scripts around it. Thanks to Julia for her help! Signed-off-by: Thomas Gleixner Cc: Julia Lawall Cc: Jiang Liu

c6x/timer64: Migrate to new 'set-state' interface

2015-08-10T09:41:00+00:00

Migrate c6x driver to the new 'set-state' interface provided by clockevents core, the earlier 'set-mode' interface is marked obsolete now. This also enables us to implement callbacks for new states of clockevent devices, for example: ONESHOT_STOPPED. We weren't doing anything in ->set_mode(RESUME) and so tick_resume() isn't implemented.

C6X/megamode-pic: Prepare megamod_irq_cascade for irq argument removal

2015-07-31T20:20:05+00:00

The irq argument of most interrupt flow handlers is unused or merily used instead of a local variable. The handlers which need the irq argument can retrieve the irq number from the irq descriptor. Search and update was done with coccinelle and the invaluable help of Julia Lawall. Signed-off-by: Thomas Gleixner Cc: Julia Lawall Cc: Mark Salter Cc: linux-c6x-dev@linux-c6x.org

C6X/meagmod-pic: Consolidate chained IRQ handler install/remove

2015-07-27T11:36:37+00:00

Chained irq handlers usually set up handler data as well. We now have a function to set both under irq_desc->lock. Replace the two calls with one. Search and conversion was done with coccinelle.

C6X: add basic support for TMS320C6678 SoC

2012-07-19T03:52:31+00:00

This patch adds support for the TMS320C6678 SoC on an EVMC6678LE evaluation board. The 6678 is a C66x family CPU which is very similar to the already supported C64x CPUs with the addition of floating point instructions.

C6X: remove megamod-pic requirement on direct-mapped core pic

2012-07-19T03:43:37+00:00

The megamodule PIC cascades a number of interrupt sources into the core priority PIC. The megamodule code depends on the core hardware interrupt numbers being mapped one-to-one with regard to linux interrupt numbers. This patch removes that dependence in order to pave the way for removing the direct mapping in the core PIC code. Signed-off-by: Mark Salter
