From 23393d49fb75ca97b179668aa86b7038c2dc0831 Mon Sep 17 00:00:00 2001 From: Rob Herring Date: Mon, 27 Jul 2015 15:55:16 -0500 Subject: gpio: kill off set_irq_flags usage 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 as most platforms don't use probing. There appears to be a great deal of blind copy and paste of this code.
