USB: OHCI: remove ohci-pcc-soc driver.

2012-10-22T18:14:24+00:00

This driver is not registered by any in-tree users, and if really needed by some out of tree user, the same functionnality can be restored using the ohci-platform driver using the following platform_data parameters: big_endian_desc = 1 big_endian_mmio = 1 no_big_frame_no = 1 Signed-off-by: Florian Fainelli Acked-by: Alan Stern Signed-off-by: Greg Kroah-Hartman

USB: ohci-ppc-soc.c: remove err() usage

2012-04-27T18:24:42+00:00

err() was a very old USB-specific macro that I thought had gone away. This patch removes it from being used in the driver and uses dev_err() instead. CC: Alan Stern Signed-off-by: Greg Kroah-Hartman

USB: irq: Remove IRQF_DISABLED

This flag is a NOOP and can be removed now. Signed-off-by: Yong Zhang Signed-off-by: Greg Kroah-Hartman

treewide: Convert uses of struct resource to resource_size(ptr)

2011-06-10T12:55:36+00:00

Several fixes as well where the +1 was missing. Done via coccinelle scripts like: @@ struct resource *ptr; @@ - ptr->end - ptr->start + 1 + resource_size(ptr) and some grep and typing. Mostly uncompiled, no cross-compilers. Signed-off-by: Joe Perches Signed-off-by: Jiri Kosina

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.

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.

usb host: fix platform driver hotplug/coldplug

Since 43cc71eed1250755986da4c0f9898f9a635cb3bf, the platform modalias is prefixed with "platform:". Add MODULE_ALIAS() to the hotpluggable USB HCDs, to allow re-enable auto loading.

USB: add runtime frame_no quirk for big-endian OHCI

2007-10-12T21:55:32+00:00

Add OHCI big endian frame_no quirk. The frame_no value stored in the HCCA is a 16 bit field at a specific offset, but since not all CPUs can do 16-bit memory accesses it's used as a 32 bit field. And that's why big-endian OHCI must shift 16 bits ... unless the spec is not followed. Currently there's one MPC52xx platform that doesn't need the shift. This patch adds a new "big endian frame_no" quirk to control that at runtime. Signed-off-by: Valentine Barshak Acked-by: Dale Farnsworth Signed-off-by: David Brownell Signed-off-by: Greg Kroah-Hartman
