Currently musb_platform_reset() is only used by dsps. In case of BABBLE interrupt for other platforms the musb_platform_reset() is a NOP. In such situations no need to re-initialize the endpoints.

2014-07-10usb: renesas_usbhs: gadget: fix re-enabling pipe without re-connectingYoshihiro Shimoda3-0/+13
This patch fixes an issue that the renesas_usbhs driver in gadget mode cannot work correctly even if I disabled DMAC of the driver when I used the g_zero driver and the testusb tool. When a usb cable is re-connected, the renesas_usbhs driver calls the usbhsp_flags_init() (via usbhs_hotplug() --> usbhs_mod_call(start) --> usbhsg_try_start() --> usbhs_pipe_init()). However, the driver doesn't call the usbhsp_flags_init() when usbhsg_ep_disable() is called. So, if a gadget driver calls usb_ep_enable() and usb_ep_disable() again and again, the renesas_usbhs driver will output the following log: renesas_usbhs renesas_usbhs: can't get pipe (BULK) renesas_usbhs renesas_usbhs: wrong recip request Acked-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Yoshihiro Shimoda <yoshihiro.shimoda.uh@renesas.com> Signed-off-by: Felipe Balbi <balbi@ti.com>

2014-06-30usb: musb: cppi41: fire hrtimer according to programmed channel lengthDaniel Mack1-2/+4
The musb/cppi41 code installs a hrtimer to work around DMA completion interrupts that have fired too early on AM335x hardware. This timer is currently programmed to first fire 140 microseconds after the DMA completion callback. According to the commit which introduced it (a655f481d83, "usb: musb: musb_cppi41: handle pre-mature TX complete interrupt"), that value is is considered a 'rule of thumb' that worked well with the test case described in the commit log. Test show, however, that for USB audio devices and much smaller packet sizes, the timer has to fire earlier in order to correctly handle the audio stream. The original test case had output transfer sizes of 1514 bytes, and a delay of 140 microseconds. For audio devices with 24 bytes channel size, 3 microseconds seem to work well. Hence, let's assume that the time it takes to clear the bit correlates with the number of bytes transferred. The referenced commit log mentions such a suspicion as well. Let the timer fire in cppi41_channel->total_len/10 microseconds to correctly handle both cases. Also, shorten the interval in which the timer fires again in case of a non-empty early_tx list. With these changes in place, both FS and HS audio devices appear to work well on AM335x hardware.

2014-06-30Revert "usb: musb: musb_cppi41: Handle ISOCH differently and not use the ↵Daniel Mack1-53/+0
hrtimer." This reverts commit 1af54b7a4. The commit tried to address cases in which isochronous transfers are 'not reliable', most probably in the tests conducted, polling for the MUSB_TXCSR_TXPKTRDY bit in MUSB_TXCSR is done too late. Hence, it installs a work struct which basically busy-polls for the bit in a rather agressive way by rescheduling the work if the FIFO is not empty. With USB audio devices, tests have shown that it takes approximately 100 iterations of the asynchronous worker until the FIFO signals completion, which leads to 100% CPU loads when streaming audio. The issue the patch tried to address can be handled differently, which is what the next patch does.

2014-06-30usb: musb/cppi41: call musb_ep_select() before accessing an endpoint's CSRDaniel Mack1-2/+7
Before accessing any of an endpoint's CSR registers, make sure the correct endpoint is selected. Otherwise, data read from or written to the registers is likely to affect the wrong endpoint as long as the connected device has more than one endpoint. This, of course, leads to all sorts of strange effects such as stream starvation and driver internal state machine confusion due to spurious interrupts.

2014-06-30usb: musb: introduce dma_channel.rx_packet_doneDaniel Mack3-1/+5
The musb/cppi41 glue layer is capable of handling transactions that span over more than one USB packet by reloading the DMA descriptors partially. An urb is considered completed when either its transfer buffer has been filled entirely (actual_length == transfer_buffer_length) or if a packet in the stream has less bytes than the endpoint's wMaxPacketSize. Once one of the above conditions is met, musb_dma_completion() is called from cppi41_trans_done(). However, the final decision whether or not to return the urb to its owner is made by the core and its determination of the variable 'done' in musb_host_rx(). This code has currently no way of knowing what the size of the last packet was, and whether or not to give back the urb due to a short read. Fix this by introducing a new boolean flag in 'struct dma_channel', and set it from musb_cppi41.c. If set, it will make the core do what the DMA layer decided and complete the urb.

2014-06-30usb: musb: use is_host_active() to distinguish between host and gadget modeDaniel Mack1-9/+7
On AM33xx platforms, unplugging a device in the middle of an active transfer leads to a drop of MUSB_DEVCTL_HM in MUSB_DEVCTL before the system is informed about a disconnect. This consequently makes the musb core call the gadget code to handle the interrupt request, which then crashes the kernel because the relevant pointers haven't been set up for gadget mode. To fix this, use is_host_active() rather than (devctl & MUSB_DEVCTL_HM) in musb_interrupt() and musb_dma_completion() to detect whether the controller is in host or peripheral mode. This information is provided by the driver logic and does not rely on register contents. Signed-off-by: Daniel Mack <zonque@gmail.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
