2011-12-21usb: dwc3: gadget: add support for SG listsFelipe Balbi1-17/+98
add support for SG lists on dwc3 driver. With this we can e.g. use VFS layer's SG lists on storage gadgets so that we can start bigger transfers and improve throughput. Signed-off-by: Felipe Balbi <balbi@ti.com>
2011-12-21usb: dwc3: gadget: don't force 'LST' alwaysFelipe Balbi1-10/+4
the LST bit is to be set on the last of a series of consecutive TRBs. We had a workaround for a problem where data would get corrupted but that doesn't happen anymore. It's likely that it was caused by some FPGA instability during development phase. Signed-off-by: Felipe Balbi <balbi@ti.com>
2011-12-21usb: dwc3: gadget: don't return anything on prepare trbsFelipe Balbi1-13/+9
all that function does is setup a TRB to be sent to HW later. There's no need to return anything actually. Signed-off-by: Felipe Balbi <balbi@ti.com>
2011-12-21usb: dwc3: gadget: re-factor dwc3_prepare_trbs()Felipe Balbi1-68/+78
In order to make it easier to add SG support, let's split the big loop out to its own function. Signed-off-by: Felipe Balbi <balbi@ti.com>
2011-12-21usb: gadget: introduce support for sg listsFelipe Balbi1-0/+10
Some controllers support scatter/gather transfers and that might be very useful for some gadget drivers. This means that we can make use of larger buffer allocations which means we will have less completion IRQs overtime, thus improving the perceived performance. Signed-off-by: Felipe Balbi <balbi@ti.com>
2011-12-21usb: renesas: pipe: convert a long if into a XOR operationFelipe Balbi1-2/+1
This is just a minor optimization for the long if we have on the driver. When we want to check that one input is true and the other must be false, the bitwise XOR operator will achieve that for us.

2011-12-21usb: gadget: s3c-hsudc: use release_mem_region instead of release_resourceHeiko Stübner1-3/+1
As the memory region is requested through request_mem_region use the correct paired method to release it in the error path and don't go "beneath the API".

2011-12-21usb: gadget: s3c-hsudc: Add regulator handlingHeiko Stübner1-4/+37
The udc has three supplies: vdda (3.3V), vddi (1.2V) and vddosc (1.8-3.3V). Turn these on and off on start and stop calls. Signed-off-by: Heiko Stuebner <heiko@sntech.de> Reviewed-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
2011-12-21usb: gadget: s3c-hsudc: use udc_start and udc_stop functionsHeiko Stübner1-30/+14
udc_start and udc_stop reduce code duplication in comparison to start and stop generalising calls done by all drivers (i.e. bind and unbind) and moving these calls to common code. Signed-off-by: Heiko Stuebner <heiko@sntech.de> Signed-off-by: Felipe Balbi <balbi@ti.com>
2011-12-21usb: gadget: s3c-hsudc: move device registration to probeHeiko Stübner1-9/+8
Instead of adding and deleting the gadget device in the start and stop invocations. Use device_register in the probe method to initialize and add the gadget device. Signed-off-by: Heiko Stuebner <heiko@sntech.de> Signed-off-by: Felipe Balbi <balbi@ti.com>

2011-12-20usb: dwc3: gadget: move us to Default State after resetFelipe Balbi1-0/+3
After a bus reset, we should move our state to Default, in order to be able to re-enumerate again. I only managed to trigger this problem with g_ether by removing the cable after a few transfers had been completed. Signed-off-by: Felipe Balbi <balbi@ti.com>

2011-12-20usb: musb: fix pm_runtime mismatchFelipe Contreras1-2/+0
In musb_init_controller() there's a pm_runtime_put(), but there's no pm_runtime_get(), which creates a mismatch that causes the driver to sleep when it shouldn't. This was introduced in 7acc619[1], but it wasn't triggered in my setup until 18a2689[2] was merged to Linus' branch at point df0914[3]. IOW; when PM is working as it was supposed to. However, it seems most of the time this is used in a way that keeps the counter above 0, so nobody noticed. Also, it seems to depend on the configuration used in versions before 3.1, but not later (or in it). I found the problem by loading isp1704_charger before any usb gadgets: http://article.gmane.org/gmane.linux.kernel/1226122 All versions after 2.6.39 are affected.
