* usb: ci_udc: use var name ep/ci_ep consistentlyStephen Warren2014-07-02-9/+9
| | | | | | | | | Almost all of ci_udc.c uses variable name "ep" for a struct usb_ep and "ci_ep" for a struct ci_ep. This is nice and consistent, and helps people know what type a variable is without searching for the declaration. handle_ep_complete() doesn't do this, so fix it to be consistent.

* USB: gadget: atmel: zero out allocated requestsStephen Warren2014-07-02-1/+1
| | | | | | | | | | | A UDC's alloc_request method should zero out the newly allocated request. Ensure the Atmel driver does so. This issue was found by code inspection, following the investigation of an intermittent issue with ci_udc, which was tracked down to failing to zero out allocated requests following some of my changes. All other UDC drivers already zero out requests in one way or another. Signed-off-by: Stephen Warren <swarren@nvidia.com>
* usb: ci_udc: don't memalign() struct ci_req allocationsStephen Warren2014-07-02-2/+1
| | | | | | | | | | struct ci_req is a purely software structure, and needs no specific memory alignment. Hence, allocate it with calloc() rather than memalign(). The use of memalign() was left-over from when struct ci_req was going to hold the aligned bounce buffer, but this is now dynamically allocated. Signed-off-by: Stephen Warren <swarren@nvidia.com>
* usb: ci_udc: remove controller.items arrayStephen Warren2014-07-02-6/+3
| | | | | | | | There's no need to store an array of QTD pointers in the controller. Since the calculation is so simple, just have ci_get_qtd() perform it at run-time, rather than pre-calculating everything. Signed-off-by: Stephen Warren <swarren@nvidia.com>
* usb: ci_udc: fix items array size/stride calculationStephen Warren2014-07-02-15/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | 2 QTDs are allocated for each EP. The current allocation scheme aligns the first QTD in each pair, but simply adds the struct size to calculate the second QTD's address. This will result in a non-cache-aligned addresss IF the system's ARCH_DMA_MINALIGN is not 32 bytes (i.e. the size of struct ept_queue_item). Similarly, the original ilist_ent_sz calculation aligned the value to ARCH_DMA_MINALIGN but didn't take the USB HW's 32-byte alignment requirement into account. This doesn't cause a practical issue unless ARCH_DMA_MINALIGN < 32 (which I suspect is quite unlikely), but we may as well fix the code to be explicit, so it's obviously completely correct. The new value of ILIST_ENT_SZ takes all alignment requirements into account, so we can simplify ci_{flush,invalidate}_qtd() by simply using that macro rather than calling roundup(). Similarly, the calculation of controller.items[i] can be simplified, since each QTD is evenly spaced at its individual alignment requirement, rather than each pair being aligned, and entries within the pair being spaced apart only by structure size.

* usb: ci_udc: lift ilist size calculations to global scopeStephen Warren2014-07-02-14/+14
| | | | | | | | | | | | This will allow functions other than ci_udc_probe() to make use of the constants in a future change. This in turn requires converting the const int variables to #defines, since the initialization of one global const int can't depend on the value of another const int; the compiler thinks it's non-constant if that dependency exists.

* usb: ci_udc: don't assume QTDs are adjacent when transmitting ZLPsStephen Warren2014-07-02-3/+4
| | | | | | | | | Fix ci_ep_submit_next_request()'s ZLP transmission code to explicitly call ci_get_qtd() to find the address of the other QTD to use. This will allow us to correctly align each QTD individually in the future, which may involve leaving a gap between the QTDs. Signed-off-by: Stephen Warren <swarren@nvidia.com>
* usb: ci_udc: fix ci_flush_{qh,qtd} calls in ci_udc_probe()Stephen Warren2014-07-02-2/+2
| | | | | | | | | | | | | | | ci_udc_probe() initializes a pair of QHs and QTDs for each EP. After each pair has been initialized, the pair is cache-flushed. The conversion from QH/QTD index [0..2*NUM_END_POINTS) to EP index [0..NUM_ENDPOINTS] is incorrect; it simply subtracts 1 (which yields the QH/QTD index of the first entry in the pair) rather than dividing by two (which scales the range). Fix this. On my system, this avoids cache debug prints due to requests to flush unaligned ranges. This is caused because the flush calls happen before the items[] array entries are initialized for all but EP0. Signed-off-by: Stephen Warren <swarren@nvidia.com>

* usb: ci_udc: fix interaction with CONFIG_USB_ETH_CDCStephen Warren2014-06-25-1/+7
| | | | | | | | | | | | | | | | | | | | | | ci_udc.c's usb_gadget_unregister_driver() doesn't call driver->unbind() unlike other USB gadget drivers. Fix it to do this. Without this, when ether.c's CDC Ethernet device is torn down, eth_unbind() is never called, so dev->gadget is never set to NULL. For some reason, usb_eth_halt() is called both at the end of the first use of the Ethernet device, and prior to any subsequent use. Since dev->gadget is never cleared, all calls to usb_eth_halt() attempt to stop, disconnect, and clean up the device, resulting in double cleanup, which hangs U-Boot on my Tegra device at least. ci_udc allocates its own singleton EP0 request object, and cleans it up during usb_gadget_unregister_driver(). This appears necessary when using the USB gadget framework in U-Boot, since that does not allocate/free the EP0 request. However, the CDC Ethernet driver *does* allocate and free its own EP0 requests. Consequently, we must protect ci_ep_free_request() against double-freeing the request.

This appears to be valid in many cases; both USB enumeration and Mass Storage work OK with this restriction. However, DFU uses ep0 to transfer data in both directions. This renders the assumption invalid; when sending data from device to host, the Data Stage is an IN transaction, and the Status Stage is an OUT transaction. Enhance handle_setup() to deduce the correct direction for the USB transactions based on Setup transaction data. ep0's request object only needs to be automatically re-queued when the Data Stage completes, in order to implement the Status Stage. Once the Status Stage transaction is complete, there is no need to re-queue the USB request, so don't do that. Don't sent USB request completion callbacks for Status Stage transactions. These were queued by ci_udc itself, and only serve to confuse the USB function code. For example, f_dfu attempts to interpret the 0-length data buffers for Status Stage transactions as DFU packets. These buffers contain stale data from the previous transaction. This causes f_dfu to complain about a sequence number mismatch. Signed-off-by: Stephen Warren <swarren@nvidia.com>

This solves a couple of issues in the current code: a) A request object always exists for ep0. Prior to this patch, if setup transactions arrived in an unexpected order, handle_setup() would need to reply to a setup transaction before any ep0 usb_req was created. This issue was introduced in commit 2813006fecda "usb: ci_udc: allow multiple buffer allocs per ep." b) handle_ep_complete no longer /has/ to queue the ep0 request again after every single request completion. This is currently required, since handle_setup() assumes it can find some request object in ep0's request queue.
