* | | | 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

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: 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>

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.
