- remove pointer u32 abuse in fusb300_fill_idma_prdtbl(). It is assigned the dma_addr to a pointer and then back. Poor families may have to recycle variables but we don't - don't free req.buf in error case. We don't do it in the ok case so it is probably wrong to do it in error case. - return in error case. There is no reason to continue without data and performing ops on an invalid pointer. - The if (d) statement is bogus since an invalid DMA pointer is ~0 on some architecutres. And since we return for the invalid case we don't need it. Signed-off-by:

udc-core checks for valid callbacks so there is no need for the driver to do so. Also "can-be-bound-once" is verified by udc-core. The pull-up callback is called by udc-core afterwords.

udc_start() should only trigger the internal state machine and make minimal house keeping. Before that call udc-core calls the bind() callback and after the callback the pullup(). udc_stop() is simillar, udc-core calls pullup(), unbind() and finally udc_stop(). Signed-off-by:

This value is now assigned during bind(). The configuration depends on static values assigned by dummy driver itself. So there is no need to defer this assigment until one know the actuall speed since the configuration is static and known early. Signed-off-by:

This is only required to be done once. There is no counter part to this in ->stop() so there is no need to re-do it next time. While here also init the max_stream size to 0 on SS speed. Signed-off-by:

Sebastian Andrzej Siewior authored
maxpacket is set by the udc driver for ep0 very early. This value is copied by the function gadget used later for the USB_DT_DEVICE and USB_DT_DEVICE_QUALIFIER query. This seems to work fine so far. For USB3 we need set a different value here. In SS speed it is 2^x with x=9 and in HS we set something <= 64. If the UDC starts in SS and continues in HS after the cable has been plugged it will report a too small value. There setting of this value is defered and taken automaticly from the ep0 pointer where the UDC driver can update it according to the speed it detected _after_ a cable has been plugged.

now that we have the udc class, we can allow multiple gadget controller drivers to be compiled as modules. This will allow for distro-like kernels for embedded devices. With this patch, I managed to build an x86 kernel with support for many of the controllers enabled: CONFIG_USB_FUSB300=m CONFIG_USB_R8A66597=m CONFIG_USB_M66592=m CONFIG_USB_AMD5536UDC=m CONFIG_USB_CI13XXX_PCI=m CONFIG_USB_NET2272=m CONFIG_USB_NET2280=m CONFIG_USB_GOKU=m CONFIG_USB_LANGWELL=m CONFIG_USB_EG20T=m Also an ARM kernel with support for many controllers: CONFIG_USB_FUSB300=m CONFIG_USB_OMAP=m CONFIG_USB_R8A66597=m CONFIG_USB_GADGET_MUSB_HDRC=m CONFIG_USB_M66592=m CONFIG_USB_NET2272=m CONFIG_USB_DUMMY_HCD=m The next step would be to get rid of the direct access to arch/ and mach/ directories on some gadget controllers so that we can build all of them without depending on their respective ARCH_* symbols.

the MUSB IP is always OTG, so there's no point in adding so many ifdefs on the code. Drop those and always compile the driver for OTG support. This also allows us to drop the useless "driver mode" choice. For doing that, we need to make musb depend on both Host and Peripheral side. Signed-off-by:
