PM: ARM: locomo: Drop suspend and resume bus type callbacks

2017-10-04T22:40:57+00:00

None of the locomo drivers in the tree implements the suspend and resume callbacks from struct locomo_driver, so drop them and drop the corresponding callbacks from locomo_bus_type. Signed-off-by: Rafael J. Wysocki Reviewed-by: Ulf Hansson

ARM: locomo: fix locomo irq handling

2016-09-12T11:12:31+00:00

Accidentally booting Collie on Assabet reveals that the locomo driver incorrectly overwrites gpio-sa1100's chip data for its parent interrupt, leading to oops in sa1100_gpio_unmask() and sa1100_update_edge_regs() when "gpio: sa1100: convert to use IO accessors" is applied. Fix locomo to use the handler data rather than chip data for its parent interrupt. Signed-off-by: Russell King

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

ARM: kill off set_irq_flags usage

2015-07-28T11:58:13+00:00

set_irq_flags is ARM specific with custom flags which have genirq equivalents. Convert drivers to use the genirq interfaces directly, so we can kill off set_irq_flags. The translation of flags is as follows: IRQF_VALID -> !IRQ_NOREQUEST IRQF_PROBE -> !IRQ_NOPROBE IRQF_NOAUTOEN -> IRQ_NOAUTOEN For IRQs managed by an irqdomain, the irqdomain core code handles clearing and setting IRQ_NOREQUEST already, so there is no need to do this in .map() functions and we can simply remove the set_irq_flags calls. Some users also modify IRQ_NOPROBE and this has been maintained although it is not clear that is really needed. There appears to be a great deal of blind copy and paste of this code.

ARM/locomo: Prepare locomo_handler for irq argument removal

2015-07-13T12:59:15+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.

ARM, irq: Use irq_desc_get_xxx() to avoid redundant lookup of irq_desc

2015-07-13T12:59:15+00:00

Use irq_desc_get_xxx() to avoid redundant lookup of irq_desc while we already have a pointer to corresponding irq_desc. Signed-off-by: Jiang Liu Cc: Russell King Cc: linux-arm-kernel@lists.infradead.org Signed-off-by: Thomas Gleixner

ARM/locomo: Consolidate chained IRQ handler install/remove

2015-07-13T12:59:14+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.

arm: Fold irq_set_chip/irq_set_handler

Use irq_set_chip_and_handler() instead. Converted with coccinelle. Signed-off-by: Thomas Gleixner

arm: Reorder irq_set_ function calls

2011-03-29T12:47:58+00:00

Reorder irq_set_chip() irq_set_chip_data() irq_set_handler() to irq_set_chip() irq_set_handler() irq_set_chip_data() so the next patch can combine irq_set_chip() and irq_set_handler() to irq_set_chip_and_handler(). Automated conversion with coccinelle. Signed-off-by: Thomas Gleixner
