USB: automatically enable RHSC interrupts

2008-08-21T17:26:38+00:00

This patch (as1069c) changes the way OHCI root-hub status-change
interrupts are enabled.  Currently a special HCD method,
hub_irq_enable(), is called when the hub driver is finished using a
root hub.  This approach turns out to be subject to races, resulting
in unnecessary polling.

The patch does away with the method entirely.  Instead, the driver
automatically enables the RHSC interrupt when no more status changes
are present.  This scheme is safe with controllers using
level-triggered semantics for their interrupt flags.

[ARM] Move include/asm-arm/arch-* to arch/arm/*/include/mach

2008-08-07T08:55:48+00:00

This just leaves include/asm-arm/plat-* to deal with.

[ARM] Remove asm/hardware.h, use asm/arch/hardware.h instead

2008-08-07T08:40:08+00:00

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.

Revert "USB: don't explicitly reenable root-hub status interrupts"

2008-07-06T17:27:25+00:00

This reverts commit e872154921a6b5256a3c412dd69158ac0b135176.

Andrey Borzenkov reports that it resulted in a totally hung machine for
him when loading the OHCI driver.  Extensive netconsole capture with
SysRq output shows that modprobe gets stuck in ohci_hub_status_data()
when probing and enabling the OHCI controller, see for example

	http://lkml.org/lkml/2008/7/5/236

for an analysis.

The problem appears to be an interrupt flood triggered by the commit
that gets reverted, and Andrey confirmed that the revert makes things
work for him again.

ohci: Rework bus glue integration to allow several at once

2007-02-07T23:44:33+00:00

The previous model had the module_init & module_exit function in the
bus glue .c files themselves. That's a problem if several glues need
to be selected at once and the driver is built has module. This case
is quite common in embedded system where you want to handle both the
integrated ohci controller and some extra controller on PCI.

The ohci-hcd.c file now provide the module_init & module_exit and
appropriate driver registering/unregistering is done conditionally,
using #ifdefs.

(space before tab, at end of line) as well as the obsolete inline changelog.

USB: OHCI avoids root hub timer polling

2006-09-27T18:58:48+00:00

This teaches OHCI to use the root hub status change (RHSC) IRQ, bypassing
root hub timers most of the time and switching over to the "new" root hub
polling scheme.  It's complicated by the fact that implementations of OHCI
trigger and ack that IRQ differently (the spec is vague there).

Avoiding root hub timers helps mechanisms like "dynamic tick" leave the
CPU in lowpower modes for longer intervals.
