* ARM: kill off set_irq_flags usageRob Herring2015-07-2835-47/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: appropriate __init annotation for const dataNicolas Pitre2015-07-2840-50/+50
| | | | | | | | | | Init data marked const should be annotated with __initconst for correctness and not __initdata. In some cases the array gathering references to that data has to be marked const as well. This fixes LTO builds that otherwise fail with section mismatch errors.

This time we're dropping the board files for omap3logic and omap3pandora. The reason for dropping these now rather than later is that now we can simply revert the patches in case of unexpected issues as we are not dropping any platform data at this point. This leaves us with only the following board-*.c files: BOARD REASON NEEDED board-ldp.c Still used in RMKs boot test system board-rx51-*.c Needs /proc/atags support for user space Once we have the n900 legacy user space issues sorted out for /proc/atags and system_rev, we can drop the remaining two board-*.c files. And then one merge window after that we can drop the legacy booting support assuming no unexpected issues are found. * tag 'omap-for-v4.3/legacy-v2-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: ARM: OMAP2+: Remove legacy booting support for Pandora ARM: OMAP2+: Remove legacy booting support for LogicPD Torpedo Signed-off-by: Olof Johansson <olof@lixom.net>

The same behavior can be achieved by using clockevents state helpers. These helpers are only required for oneshot mode as shutdown/resume wouldn't be done twice by the core.
