2011-05-09xHCI 1.0: Block Interrupts for Isoch transferAndiry Xu2-0/+7
Currently an isoc URB is divided into multiple TDs, and every TD will trigger an interrupt when it's processed. However, software can schedule multiple TDs at a time, and it only needs an interrupt every URB. xHCI 1.0 introduces the Block Event Interrupt(BEI) flag which allows Normal and Isoch Transfer TRBs to place an Event TRB on an Event Ring but not assert an intrrupt to the host, and the interrupt rate is significantly reduced and the system performance is improved.

2011-05-09xHCI 1.0: Setup Stage TRB Transfer Type flagAndiry Xu2-0/+14
Setup Stage Transfer Type field is added to indicate the presence and the direction of the Data Stage TD, and determines the direction of the Status Stage TD so the wLength length field should be ignored by the xHC.

2011-05-09drm/i915/lvds: Only act on lid notify when the device is onAlex Williamson1-0/+3
If we're using vga switcheroo, the device may be turned off and poking it can return random state. This provokes an OOPS fixed separately by 8ff887c847 (drm/i915/dp: Be paranoid in case we disable a DP before it is attached). Trying to use and respond to events on a device that has been turned off by the user is in principle a silly thing to do.

2011-05-09drm/i915: fix intel_crtc_clock_get pipe reads after "cleanup cleanup"Chris Wilson1-2/+2
Despite the fixes in 548f245ba6a31 (drm/i915: fix per-pipe reads after "cleanup"), we missed one neighbouring read that was mistakenly replaced with the reg value in 9db4a9c (drm/i915: cleanup per-pipe reg usage). This was preventing us from correctly determining the mode the BIOS left the panel in for machines that neither have an OpRegion nor access to the VBT, (e.g. the EeePC 700).

When enabling the plane, it is helpful to have already pointed that plane to valid memory or else we may incur the wrath of a PGTBL_ER. This code preserved the behaviour from the bad old days for unknown reasons... Found by assert_fb_bound_for_plane().

2011-05-09drm/nouveau: Fix a crash at card takedown for NV40 and older cardsJimmy Rentz2-2/+5
NV40 and older cards (pre NV50) reserve a vram bo for the vga memory at card init. This bo is then freed at card shutdown. The problem is that the ttm bo vram manager was already freed. So a crash occurs when the vga bo is freed. The fix is to free the vga bo prior to freeing the ttm bo vram manager. There might be other solutions but this seemed the simplest to me.

Implement good battery algorithm defined in the battery charging V1.2 spec for detecting different charging ports. USB hardware is put into low power mode when connected to a dedicated charging port. vbus_draw and set_power methods are implemented for determining the allowed current from Host in different states (un-configured/suspend/configured). The charger block is implemented using vendor specific registers and the PHY used in MSM8960(28nm PHY) different from older targets like MSM8x60 and MSM7x30(45nm PHY). The PHY vendor and product id registers are not implemented in the above chipsets. Hence PHY type is passed via platform data.

This patch is part of a series that extend the UHCI HCD to support non-PCI host controllers. This patch also extends the uhci_{read,write}* functions to allow accesses to registers not mapped into PCI I/O space. This extension also includes the addition of a void __iomem pointer to the uhci structure. A new Kconfig option is added to signal that the system has a non-PCI HC. If this Kconfig option is set, uhci-hcd.c will include generic reset functions for systems that do not make use of keyboard and mouse legacy support. PCI controllers will still always use the reset functions from pci-quirks This patch is followed by a patch that adds bus glue for the first non-PCI UHCI HC.
