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 adds support for the UHCI part of the GRLIB GRUSBHC controller found on some LEON/GRLIB SoCs. The UHCI HCD previously only supported controllers connected over PCI. This patch adds support for the first non-PCI UHCI HC. I have tried to replicate the solution used in ehci-hcd.c. Tested on GR-LEON4-ITX board (LEON4/GRLIB with GRUSBHC) and x86 with Intel UHCI HC.

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.

Though USB controller works without this most of the time, an issue was faced where USB was configured as printer device and it was dropping first packet(64 bytes) in full speed mode due to DATA PID mismatch. The problem gets resolved once unused endpoints are configured as bulk. As per P1020 RM (Table17-31, bits 19-18, bits 3-2) "When only one endpoint (RX or TX, but not both) of an endpoint pair is used, the unused endpoint should be configured as a bulk type endpoint." So according to the RM, this patch is initializing TX and RX endpoints as bulk type Signed-off-by: NSuchit Lepcha <Suchit.Lepcha@freescale.com> Signed-off-by: NRamneek Mehresh <ramneek.mehresh@freescale.com> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

The two first HC capability registers (CAPLENGTH and HCIVERSION) are defined as one 8-bit and one 16-bit register. Most HC implementations have selected to treat these registers as part of a 32-bit register, giving the same layout for both big and small endian systems. This patch adds a new quirk, big_endian_capbase, to support controllers with big endian register interfaces that treat HCIVERSION and CAPLENGTH as individual registers.

Some of the simulators may cache the ep0 maxpacket size to zero if the ep0 dQh is not setup before enabling the pullup. Hence Setup ep0 and initialize the dQh fields once while registering the gadget(before enabling the pullup). HSUSB Chipidea link controller spec says ep0 is enabled always in the HW. Hence disabling and enabling the ep0 as a part of reset interrupt is unneccesary. Remove the disable/enable ep0 logic from reset interrupt handling.

This patch replaces the code that handles qtds. Intead of directly allocating chip mem and chip slot, enqueue the transfer in a list of queue heads. Use a centralized function enqueue_qtds() to prioritize and enqueue transfers. This removes all of the interrupt context BUG() calls when out of chip mem or transfer slots. It also makes it possible to efficiently use the dual-port mem on the chip for double-buffered transfers, which improve transfer times to/from/between usb sticks by about 40 % on my HW. With this patch it should also be possible to handle qtd scheduling outside of the interrupt handler, for significantly improved kernel latency. I have not implemented this since there are some locking issues which I haven't had time to look at.
