* ehci: Check individual port status registers on resumeMatthew Garrett2011-02-251-1/+22
| | | | | | | | | | | If a device plug/unplug is detected on an ATI SB700 USB controller in D3, it appears to set the port status register but not the controller status register. As a result we'll fail to detect the plug event. Check the port status register on resume as well in order to catch this case.

* usb: musb: OMAP4430: Fix usb device detection if connected during bootHema HK2011-02-182-5/+52
| | | | | | | | | | | | | | | | | | | | | | | | | | OMAP4430 is embedded with UTMI PHY. This PHY does not support the OTG features like ID pin detection and VBUS detection. This function is exported to an external companion chip TWL6030. Software must retrieve the OTG HNP and SRP status from the TWL6030 and configure the bits inside the control module that drive the related USBOTGHS UTMI interface signals. It must also read back the UTMI signals needed to configure the TWL6030 OTG module. Can find more details in the TRM[1]. [1]:http://focus.ti.com/pdfs/wtbu/OMAP4430_ES2.0_Public_TRM_vJ.pdf In OMAP4430 musb driver VBUS and ID notifications are received from the transceiver driver. If the cable/device is connected during boot, notifications from transceiver driver will be missed till musb driver is loaded. Patch to configure the transceiver in the platform_enable/disable functions and enable the vbus in the gadget driver based on the last_event of the otg_transceiver.

| | | | | | | | | | | | | | | | | | usb_gadget_probe_driver()/usb_gadget_unregister_driver Just a few cosmetic fixes to usb_gadget_probe_driver() and usb_gadget_unregister_driver(). Decreased a few indentation levels with goto statements. While at that, also add the missing call to musb_stop(). If we don't have OTG, there's no point of leaving MUSB prepared for operation if a gadget driver fails to probe. The same is valid for usb_gadget_unregister_driver(), since we are removing the gadget driver and we don't have OTG, we can completely unconfigure MUSB. Signed-off-by: Felipe Balbi <balbi@ti.com>

* USB: isp1760: Implement solution for erratum 2Sebastian Andrzej Siewior2011-02-172-6/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The document says: |2.1 Problem description | When at least two USB devices are simultaneously running, it is observed that | sometimes the INT corresponding to one of the USB devices stops occurring. This may | be observed sometimes with USB-to-serial or USB-to-network devices. | The problem is not noticed when only USB mass storage devices are running. |2.2 Implication | This issue is because of the clearing of the respective Done Map bit on reading the ATL | PTD Done Map register when an INT is generated by another PTD completion, but is not | found set on that read access. In this situation, the respective Done Map bit will remain | reset and no further INT will be asserted so the data transfer corresponding to that USB | device will stop. |2.3 Workaround | An SOF INT can be used instead of an ATL INT with polling on Done bits. A time-out can | be implemented and if a certain Done bit is never set, verification of the PTD completion | can be done by reading PTD contents (valid bit). | This is a proven workaround implemented in software. Russell King run into this with an USB-to-serial converter. This patch implements his suggestion to enable the high frequent SOF interrupt only at the time we have ATL packages queued. It goes even one step further and enables the SOF interrupt only if we have more than one ATL packet queued at the same time.

* USB: s3c2410_udc: Add handling for S3C244X dual-packet modeFabian Godehardt2011-02-171-1/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a patch that seems to make the USB hangs on the S3C244X go away. At least a good amount of ping torture didn't make them come back so far. The issue is that, if there are several back-to-back packets, sometimes no interrupt is generated for one of them. This seems to be caused by the mysterious dual packet mode, which the USB hardware enters automatically if the endpoint size is half that of the FIFO. (On the 244X, this is the normal situation for bulk data endpoints.) There is also a timing factor in this. It seems that what happens is that the USB hardware automatically sends an acknowledgement if there is only one packet in the FIFO (the FIFO has space for two). If another packet arrives before the host has retrieved and acknowledged the previous one, no interrupt is generated for that second one. However, there may be an indication. There is one undocumented bit (none of the 244x manuals document it), OUT_CRS1_REG[1], that seems to be set suspiciously often when this condition occurs. There is also CLR_DATA_TOGGLE, OUT_CRS1_REG[7], which may have a function related to this. (The Samsung manual is rather terse on that, as usual.) This needs to be examined further. For now, the patch seems to do the trick. Signed-off-by: Vasily Khoruzhick <anarsoul@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

| | | * | drm/i915/tv: Use polling rather than interrupt-based hotplugChris Wilson2011-02-111-13/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The documentation recommends that we should use a polling method for TV detection as this is more power efficient than the interrupt based mechanism (as the encoder can be completely switched off). A secondary effect is that leaving the hotplug enabled seems to be causing pipe underruns as reported by Hugh Dickins on his Crestline.

| | | * | drm/i915: Trigger modesetting if force-audio changesChris Wilson2011-02-113-18/+91
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the user changes the force-audio property and it no longer reflects the current configuration, then we need to trigger a mode set in order to update the registers.

| | | * | drm/i915/sdvo: If we have an EDID confirm it matches the mode of the connectionChris Wilson2011-02-091-5/+27

This should reduce the number of bogus outputs on multi-function adapters that report the same output on multiple connectors.
