2015-07-28ARM: kill off set_irq_flags usageRob Herring
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.

2008-08-07[ARM] Move include/asm-arm/arch-* to arch/arm/*/include/machRussell King
This just leaves include/asm-arm/plat-* to deal with. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-08-07[ARM] Remove asm/hardware.h, use asm/arch/hardware.h insteadRussell King
Remove includes of asm/hardware.h in addition to asm/arch/hardware.h. Then, since asm/hardware.h only exists to include asm/arch/hardware.h, update everything to directly include asm/arch/hardware.h and remove asm/hardware.h. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2007-05-16[ARM] 4383/1: iop: fix usage of '__init' and 'inline' in iop filesDan Williams
WARNING: arch/arm/mach-iop13xx/built-in.o - Section mismatch: reference to .init.text:iop13xx_pcie_map_irq from .text between 'iop13xx_pci_setup' (at offset 0x7fc) and 'iop13xx_map_pci_memory' While fixing this warning I also recalled Adrian Bunk's recommendation to not use inline in .c files, as 'iop13xx_map_pci_memory' is needlessly inlined. Removing 'inline' uncovered some dead code so that is cleaned up as well. Signed-off-by: Dan Williams <dan.j.williams@intel.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2007-02-17[ARM] 4186/1: iop: remove cp6_enable/disable routinesDan Williams

2007-02-14[ARM] 4184/1: iop: cp6 access handler (undef_hook)Dan Williams
Enable svc access to cp6 via an undefined instruction hook. Do not enable access for usr code. This patch also makes iop13xx select PLAT_IOP, this requires a small change to drivers/i2c/busses/i2c-iop3xx.c. Per Lennert Buytenhek's note, the cp6 trap routine is moved to arch/arm/plat-iop Per Nicolas Pitre's note, the cp_wait is skipped since the latency to return to the faulting function is longer than cp_wait.

2006-09-25[ARM] 3832/1: iop3xx: coding style cleanupLennert Buytenhek
Since the iop32x code isn't iop321-specific, and the iop33x code isn't iop331-specfic, do a s/iop321/iop32x/ and s/iop331/iop33x/, and tidy up the code to conform to the coding style guidelines somewhat better.

2006-09-25[ARM] 3825/1: iop3xx: use cp6 enable/disable macrosLennert Buytenhek
Add CP6 enable/disable sequences to the timekeeping code and the IRQ code. As a result, we can't depend on CP6 access being enabled when we enter get_irqnr_and_base anymore, so switch the latter over to using memory-mapped accesses for now.
