As descriptor dma mode does not support split transfers, it can't be enabled for high speed devices. Add a core parameter to enable it for full speed devices. Ensure frame list and descriptor list are correctly freed during disconnect. Acked-by:

timeval is deprecated and not y2038 safe. Its size also changes according to 32 bit/ 64 bit compilation. Replace it with 32 and 64 bit versions of its individual fields, giving two ioctls with different code values. The two ioctls are necessary to maintain the 32 bit and 64 bit userspace compatibility with a 64/32 bit kernel. Change unsigned to __u32 types for a definitive userspace interface. This is in accordance with the psABI that the unsigned type is always 32 bits. Also use motonic timer instead of real time to ensure positive delta values. Refactor usbtest_ioctl for readability to isolate the handling of the testing timing measurement. The official testusb userspace tool can be changed in a separate patch to reflect the __u32 changes as well. It can use the usbtest_param_32 struct, since 32 bit seconds is long enough for test durations. Reviewed-by:

This patch modifies the ep.caps.type_{iso,bulk,int} setting and the second argument of usb_ep_maxpacket_limit() using the dparam.pipe_configs. In the previous code, all the type_{iso,bulk,int} were set to true. However, to avoid waste time for finding suitable pipe in usb_ep_enable(), this driver should set correct type. Also the second argument of usb_ep_maxpacket_limit() was set to 512 even if the pipe is isochronous or interrupt. So, this driver could not bind a gadget driver like the g_audio driver.

The current code has info->bufnmb_last to calculate the BUFNMB bits of PIPEBUF register. However, since the bufnmb_last is initialized in the usbhs_pipe_init() only, this driver is possible to set unexpected value to the register if usb_ep_{enable,disable}() are called many times. So, this patch modifies the pipe configuration via struct renesas_usbhs_driver_param to simplify the code. Also this patch changes: - a double buffer configuration - isochronous buffer size from 512 to 1024 Signed-off-by:

Isochronous descriptor is currently programmed for the frame after the last descriptor was programmed. If the last descriptor frame underrun, then current descriptor must take this into account and must be programmed on the current frame + 1. This overrun usually happens when system is loaded and dwc2 can't init descriptor list in time. Acked-by:

Gregory Herrero authored
When completing non isoc xfer, dwc2_complete_non_isoc_xfer_ddma() is relying on qtd->n_desc to process the corresponding number of descriptors. During the processing of these descriptors, qtd could be unlinked and freed if xfer is done and urb is no more in progress. In this case, dwc2_complete_non_isoc_xfer_ddma() will read again qtd->n_desc whereas qtd has been freed. This will lead to unpredictable results since qtd->n_desc is no more valid value. To avoid this error, return a result != 0 in dwc2_process_non_isoc_desc(), so that dwc2_complete_non_isoc_xfer_ddma() stops desc processing. This has been seen with Slub debug enabled. Acked-by:

For simple platforms which merely enable some clocks and populate its children, we can use this generic glue layer to avoid boilerplate code duplication. For now this supports Qcom and Xilinx, but if we find a way to add generic handling of regulators and optional PHYs, we can absorb exynos as well. Tested-by:

It just ocurred to me that dwc3 already gives a really hint of when a setup packet is pending and that's the SETUP_PENDING TRB Status for EP0 IRQs. Fix setup_packet_pending initialization based on that. While at that, also make sure the comment in gadget.c matches what code is doing. Signed-off-by:

In dwc3_cleanup_done_reqs() we expect that all iterations of our while (1) loop will find a valid struct dwc3_request *. In case we don't, we're dumping a WARN_ON_ONCE() splat so that people report the failure. This patch is a simple cleanup converting: if (!req) { WARN_ON_ONCE(1); return 1; } to: if (WARN_ON_ONCE(!req)) return 1; which is a little easier to read. Signed-off-by:

Jan Stancek reported that I wrecked things for him by fixing things for Vladimir :/ His report was due to an UNINTERRUPTIBLE wait getting -EINTR, which should not be possible, however my previous patch made this possible by unconditionally checking signal_pending(). We cannot use current->state as was done previously, because the instruction after the store to that variable it can be changed. We must instead pass the initial state along and use that.
