      [ARM] pass reboot command line to arch_reset() · be093beb
      由 Russell King 提交于 
      OMAP wishes to pass state to the boot loader upon reboot in order to
instruct it whether to wait for USB-based reflashing or not.  There is
already a facility to do this via the reboot() syscall, except we ignore
the string passed to machine_restart().

This patch fixes things to pass this string to arch_reset().  This means
that we keep the reboot mode limited to telling the kernel _how_ to
perform the reboot which should be independent of what we request the
boot loader to do.

      [ARM] pxa: introduce pxa{25x,27x,300,320,930}.h for board usage · 51c62982
      由 Eric Miao 提交于 
      Considering the header mess ATM, it is not always possible to include
the correct header files within board code. Let's keep this simple:

  <mach/pxa25x.h>  - for pxa25x based platforms
  <mach/pxa27x.h>  - for pxa27x based platforms
  <mach/pxa300.h>  - for pxa300 based platforms
  <mach/pxa320.h>  - for pxa320 based platforms
  <mach/pxa930.h>  - for pxa930 based platforms

NOTE:

1. one header one board file, they are not compatible (i.e. they have
   conflicting definitions which won't compile if included together).

2. Unless strictly necessary, the following header files are considered
   to be SoC files use _only_, and is not recommended to be included in
   board code:

    <mach/hardware.h>
    <mach/pxa-regs.h>
    <mach/pxa2xx-regs.h>
    <mach/pxa3xx-regs.h>
    <mach/mfp.h>
    <mach/mfp-pxa2xx.h>
    <mach/mfp-pxa25x.h>
    <mach/mfp-pxa27x.h>
    <mach/mfp-pxa3xx.h>
    <mach/mfp-pxa300.h>

      IRQ: Use the new typedef for interrupt handler function pointers · 40220c1a
      由 David Howells 提交于 
      Use the new typedef for interrupt handler function pointers rather than
actually spelling out the full thing each time.  This was scripted with the
following small shell script:

#!/bin/sh
egrep -nHrl -e 'irqreturn_t[ 	]*[(][*]' $* |
while read i
do
    echo $i
    perl -pi -e 's/irqreturn_t\s*[(]\s*[*]\s*([_a-zA-Z0-9]*)\s*[)]\s*[(]\s*int\s*,\s*void\s*[*]\s*[)]/irq_handler_t \1/g' $i || exit $?

      USB: pxa2xx_udc understands GPIO based VBUS sensing · b2bbb20b
      由 David Brownell 提交于 
      This updates the PXA 25x UDC board-independent infrastructure for VBUS sensing
and the D+ pullup.  The original code evolved from rather bizarre support on
Intel's "Lubbock" reference hardware, so that on more sensible hardware it
doesn't work as well as it could/should.

The change is just to teach the UDC driver how to use built-in PXA GPIO pins
directly.  This reduces the amount of board-specfic object code needed, and
enables the use of a VBUS sensing IRQ on boards (like Gumstix) that have one.
With VBUS sensing, the UDC is unclocked until a host is actually connected.

      [ARM] Remove asm/arch/irq.h · 411ef7f4
      由 Russell King 提交于 
      asm/arch/irq.h used to be included from asm/irq.h, but was removed
from the ARM kernel a long time ago.  Consequently, the contents
of asm/arch/irq.h (which mostly contain a definition for fixup_irq())
have not been used.  Hence, remove asm/arch/irq.h.

Some machine support files incorrectly included this file, making
little or no use of the contents.  Move the contents to a local
include file, and remove those include statements as well.

      [PATCH] IRQ type flags · 9ded96f2
      由 Russell King 提交于 
      Some ARM platforms have the ability to program the interrupt controller to
detect various interrupt edges and/or levels.  For some platforms, this is
critical to setup correctly, particularly those which the setting is dependent
on the device.

Currently, ARM drivers do (eg) the following:

	err = request_irq(irq, ...);

	set_irq_type(irq, IRQT_RISING);

However, if the interrupt has previously been programmed to be level sensitive
(for whatever reason) then this will cause an interrupt storm.

Hence, if we combine set_irq_type() with request_irq(), we can then safely set
the type prior to unmasking the interrupt.  The unfortunate problem is that in
order to support this, these flags need to be visible outside of the ARM
architecture - drivers such as smc91x need these flags and they're
cross-architecture.

Finally, the SA_TRIGGER_* flag passed to request_irq() should reflect the
property that the device would like.  The IRQ controller code should do its
best to select the most appropriate supported mode.

      [ARM] 3093/1: SharpSL PCMCIA Updates for Cxx00 models · a63ae442
      由 Richard Purdie 提交于 
      Patch from Richard Purdie

The Sharp SL-Cxx00 models have a combined power control for the SD
and CF slot 0. This patch adds hooks to the scoop driver to allow
machines to provide a custom control function for this and such a
function is added for spitz/akita/borzoi.

It also moves the gpio init code into the machine files as this
is machine dependent and differs between some models. A couple of
warnings when compiling for collie are also fixed.
