* mfd: max899x: Avoid redundant irq_data lookupThomas Gleixner2015-08-111-6/+3
| | | | | | | | | | | | It's pretty silly to do irq_data *d = irq_get_irq_data(irq_data->irq); because that results in d = irq_data, but goes through a lookup of the irq_data. Use irq_data directly. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Lee Jones <lee.jones@linaro.org>
* mfd: Kill off set_irq_flags usageRob Herring2015-08-111-4/+1
| | | | | | | | | | | | | | | | | | | | | 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.

* mfd: Constify regmap and irq configuration dataKrzysztof Kozlowski2015-06-221-1/+1

* mfd: max8998: Add irq domain supportTomasz Figa2013-06-301-25/+40
| | | | | | | | | | | This patch adds irq domain support for max8998 interrupts. To keep both non-DT and DT worlds happy, simple domain is used, which is linear when no explicit IRQ base is specified and legacy, with static mapping, otherwise.
