| * usb: dwc3: gadget: drop useless codeFelipe Balbi2012-06-06
| | | | | | | | | | | | | | | | We never set CMDIOC bit for Start Transfer command, so that code will never be used. Tested-by: Pratyush Anand <pratyush.anand@st.com> Signed-off-by: Felipe Balbi <balbi@ti.com>

| | | | | | | | | | | | | | | | | | If event status says that its last completed TRB but TRB is still owned by HW then break from the loop, because we are not going to get correct TRB status from trb control/size register.

| * usb: dwc3: Fix missed isoc IN transactionPratyush Anand2012-06-04
| | | | | | | | | | | | | | | | | | | | If an IN transfer is missed on isoc endpoint, then driver must insure that next ep_queue is properly handled. This patch fixes this issue by starting a new transfer for next queued request. Signed-off-by: Pratyush Anand <pratyush.anand@st.com> Signed-off-by: Felipe Balbi <balbi@ti.com>

| * USB: DWC3: Generate interrupt on each TRB as default optionPratyush Anand2012-06-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently in case of isoc, interrupt is programmed after each TRB_NUM/4 ie 8th TRB. A TRB is programmed against each submitted request from gadget. If we do not want to limit the minimum number of necessary request to be submitted from gadget then we must receive interrupt on each TRB submission. There can be such situation with a gadget working with ping-pong buffer. If a gadget does not want to receive interrupt after each request completion then it may set no_interrupt flag.

| * usb: dwc3: ep0: rename dwc3_ep0_complete_req to dwc3_ep0_complete_statusFelipe Balbi2012-06-03
| | | | | | | | | | | | | | | | | | | | That's a much more intuitive name as that function is only called at the completion of a Status Phase. It also matches dwc3_ep0_complete_data() for the completion of Data Phase. Signed-off-by: Felipe Balbi <balbi@ti.com>

| * usb: dwc3: gadget: move AcceptU1Ena and AcceptU2Ena to Reset IRQGerard CAUVY2012-06-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to the databook, the DWC3 Core will reset those bits to 0 on USB Bus Reset. This means we must re-enable those bits on every reset interrupt. Because we will always get a Reset interrupt after loading a gadget driver, we can, instead of re-enabling something that was just lost, move the handling of those bits to the Reset Interrupt.

Since proper handling is already done on dwc3_ep0_do_control_data(), we simply re-factor that function so it can be re-used from __dwc3_gadget_ep0_queue().

Some UDCs have been converted to clk_prepare_enable() and clk_disable_unprepare(). Marvell now got support for its USB3 controller in mainline after introducing its mv_u3d_core.c driver.

We also have some patches implementing a few extra Standard requests introduced by USB3 spec (Set SEL and Set Isoch Delay), as well as one patch, which has been pending for a long time, implementing LPM support. Last, but not least, we are splitting the host address space out of the dwc3 core driver otherwise xHCI won't be able to request_mem_region() its own address space. This patch is only needed because we are (as we should) re-using the xHCI driver, which is a completely separate module. Together with these three big changes, come a few extra preparatory patches which most move code around, define macros and so on, as well as a fix for Isochronous transfers which hasn't been triggered before.

The highlight on this merge is the support for Samsung's Exynos platform, increasing the number of different users for this driver to three. Note that Samsung Exynos glue layer will only compile on platforms which provide implementation for the clk API for now.
