c6x/timer64: Set ->min_delta_ticks and ->max_delta_ticks

2017-04-14T20:11:18Z

In preparation for making the clockevents core NTP correction aware, all clockevent device drivers must set ->min_delta_ticks and ->max_delta_ticks rather than ->min_delta_ns and ->max_delta_ns: a clockevent device's rate is going to change dynamically and thus, the ratio of ns to ticks ceases to stay invariant. Make the c6x arch's clockevent driver initialize these fields properly. This patch alone doesn't introduce any change in functionality as the clockevents core still looks exclusively at the (untouched) ->min_delta_ns and ->max_delta_ns. As soon as this has changed, a followup patch will purge the initialization of ->min_delta_ns and ->max_delta_ns from this driver.

c6x: Remove unnecessary of_platform_populate with default match table

2016-06-23T19:59:39Z

After patch "of/platform: Add common method to populate default bus", it is possible for arch code to remove unnecessary callers of of_platform_populate with default match table. Cc: Mikael Starvik Cc: Jesper Nilsson Signed-off-by: Kefeng Wang Signed-off-by: Rob Herring

irqdomain: Use irq_domain_get_of_node() instead of direct field access

2015-10-13T17:01:23Z

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

2015-09-16T13:47:51Z

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

There is a fix available, but I let it breed for a couple of days first.

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

2015-08-10T09:41:00Z

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

2015-07-31T20:20:05Z

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.

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

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.
