      ARM: plat-iop: instantiate GPIO from platform device · 7b85b867
      Linus Walleij authored
      This converts the IOP32x and IOP33x platforms to pass their
      base address offset by a resource attached to a platform device
      instead of using static offset macros implicitly passed
      through <linux/gpio.h> including <mach/gpio.h>. Delete the
      local <mach/gpio.h> and <asm/hardware/iop3xx-gpio.h> headers
      and remove the selection of NEED_MACH_GPIO_H.
      
      Pass the virtual address as a resource in the platform device
      at this point for bisectability, next patch will pass the
      physical address as is custom.

      ARM: iop32x: read N2100 power key using gpiolib · afc3b79f
      Linus Walleij authored
      Refrain from using the custom gpio_line_get() to read the power
      key on the N2100, use the gpiolib function gpio_get() instead.
      Also request the line in the GPIOs initicall, and move the poll
      timer setup to that inicall so the gpio chip is available before
      we request this GPIO and start to poll it.

      ARM: iop32x: request and issue reset using gpio · 7111f878
      Linus Walleij authored
      As the IOP GPIO driver supports gpiolib we can use the standard
      GPIO calls to issue a reset of the machine instead of using the
      custom gpio_line_set/config calls. Also request the GPIO when
      initializing the machine.

      ARM: PCI: provide a default bus scan implementation · c23bfc38
      Russell King authored
      Most PCI implementations perform simple root bus scanning.  Rather than
      having each group of platforms provide a duplicated bus scan function,
      provide the PCI configuration ops structure via the hw_pci structure,
      and call the root bus scanning function from core ARM PCI code.

      ARM: PCI: get rid of pci_std_swizzle() · daeb4c0c
      Russell King authored
      Most PCI implementations use the standard PCI swizzle function, which
      handles the well defined behaviour of PCI-to-PCI bridges which can be
      found on cards (eg, four port ethernet cards.)
      
      Rather than having almost every platform specify the standard swizzle
      function, make this the default when no swizzle function is supplied.
      Therefore, a swizzle function only needs to be provided when there is
      something exceptional which needs to be handled.
      
      This gets rid of the swizzle initializer from 47 files, and leaves us
      with just two platforms specifying a swizzle function: ARM Integrator
      and Chalice CATS.

      PCI: Make the struct pci_dev * argument of pci_fixup_irqs const. · d5341942
      Ralf Baechle authored
      Aside of the usual motivation for constification,  this function has a
      history of being abused a hook for interrupt and other fixups so I turned
      this function const ages ago in the MIPS code but it should be done
      treewide.
      
      Due to function pointer passing in varous places a few other functions
      had to be constified as well.

      arm: remove machine_desc.io_pg_offst and .phys_io · 6451d778
      Nicolas Pitre authored
      Since we're now using addruart to establish the debug mapping, we can
      remove the io_pg_offst and phys_io members of struct machine_desc.
      
      The various declarations were removed using the following script:
      
        grep -rl MACHINE_START arch/arm | xargs \
        sed -i '/MACHINE_START/,/MACHINE_END/ { /\.\(phys_io\|io_pg_offst\)/d }'

      include cleanup: Update gfp.h and slab.h includes to prepare for breaking... · 5a0e3ad6
      Tejun Heo authored
      include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h
      
      percpu.h is included by sched.h and module.h and thus ends up being
      included when building most .c files.  percpu.h includes slab.h which
      in turn includes gfp.h making everything defined by the two files
      universally available and complicating inclusion dependencies.
      
      percpu.h -> slab.h dependency is about to be removed.  Prepare for
      this change by updating users of gfp and slab facilities include those
      headers directly instead of assuming availability.  As this conversion
      needs to touch large number of source files, the following script is
      used as the basis of conversion.
      
        http://userweb.kernel.org/~tj/misc/slabh-sweep.py
      
      The script does the followings.
      
      * Scan files for gfp and slab usages and update includes such that
        only the necessary includes are there.  ie. if only gfp is used,
        gfp.h, if slab is used, slab.h.
      
      * When the script inserts a new include, it looks at the include
        blocks and try to put the new include such that its order conforms
        to its surrounding.  It's put in the include block which contains
        core kernel includes, in the same order that the rest are ordered -
        alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
        doesn't seem to be any matching order.
      
      * If the script can't find a place to put a new include (mostly
        because the file doesn't have fitting include block), it prints out
        an error message indicating which .h file needs to be added to the
        file.
      
      The conversion was done in the following steps.
      
      1. The initial automatic conversion of all .c files updated slightly
         over 4000 files, deleting around 700 includes and adding ~480 gfp.h
         and ~3000 slab.h inclusions.  The script emitted errors for ~400
         files.
      
      2. Each error was manually checked.  Some didn't need the inclusion,
         some needed manual addition while adding it to implementation .h or
         embedding .c file was more appropriate for others.  This step added
         inclusions to around 150 files.
      
      3. The script was run again and the output was compared to the edits
         from #2 to make sure no file was left behind.
      
      4. Several build tests were done and a couple of problems were fixed.
         e.g. lib/decompress_*.c used malloc/free() wrappers around slab
         APIs requiring slab.h to be added manually.
      
      5. The script was run on all .h files but without automatically
         editing them as sprinkling gfp.h and slab.h inclusions around .h
         files could easily lead to inclusion dependency hell.  Most gfp.h
         inclusion directives were ignored as stuff from gfp.h was usually
         wildly available and often used in preprocessor macros.  Each
         slab.h inclusion directive was examined and added manually as
         necessary.
      
      6. percpu.h was updated not to include slab.h.
      
      7. Build test were done on the following configurations and failures
         were fixed.  CONFIG_GCOV_KERNEL was turned off for all tests (as my
         distributed build env didn't work with gcov compiles) and a few
         more options had to be turned off depending on archs to make things
         build (like ipr on powerpc/64 which failed due to missing writeq).
      
         * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
         * powerpc and powerpc64 SMP allmodconfig
         * sparc and sparc64 SMP allmodconfig
         * ia64 SMP allmodconfig
         * s390 SMP allmodconfig
         * alpha SMP allmodconfig
         * um on x86_64 SMP allmodconfig
      
      8. percpu.h modifications were reverted so that it could be applied as
         a separate patch and serve as bisection point.
      
      Given the fact that I had only a couple of failures from tests on step
      6, I'm fairly confident about the coverage of this conversion patch.
      If there is a breakage, it's likely to be something in one of the arch
      headers which should be easily discoverable easily on most builds of
      the specific arch.

      i2c: Convert most new-style drivers to use module aliasing · 3760f736
      Jean Delvare authored
      Based on earlier work by Jon Smirl and Jochen Friedrich.
      
      Update most new-style i2c drivers to use standard module aliasing
      instead of the old driver_name/type driver matching scheme. I've
      left the video drivers apart (except for SoC camera drivers) as
      they're a bit more diffcult to deal with, they'll have their own
      patch later.
