* usb: mv_udc: Rename to ci_udcMarek Vasut2014-02-06-102/+102
| | | | | | | | | | The mv_udc is not marvell-specific anymore. The mv_udc is used to drive generic ChipIdea CI13xxx series OTG cores, so rename the driver to ci_udc instead.

* usb:gadget:f_thor: Allocate request up to THOR_PACKET_SIZE not ep->maxpacketLukasz Majewski2014-02-06-1/+1
| | | | | | | | Now it is possible to allocate static request - which receives data from the host (OUT transaction) to the size of THOR packet. Signed-off-by: Lukasz Majewski <l.majewski@samsung.com> Cc: Marek Vasut <marex@denx.de>
* usb:udc:samsung: Zero copy approach for data passed to Samsung's UDC driverLukasz Majewski2014-02-06-40/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | The Samsung's UDC driver is not anymore copying data from USB requests to aligned internal buffers. Now it works directly in data allocated in the upper layers like UMS, DFU, THOR. This change is possible since those gadgets now must take care to allocate buffers aligned to cache line (CONFIG_SYS_CACHELINE_SIZE). This can be achieved by using DEFINE_CACHE_ALIGN_BUFFER() or ALLOC_CACHE_ALIGN_BUFFER() macros. Those take care to allocate buffer aligned to cache line in both starting address and its size. Sometimes it is enough to just use memalign() with size being a multiplication of cache line size.

* usb:udc:samsung: Allow burst transfers for non EP0 endpintsLukasz Majewski2014-02-06-4/+3
| | | | | | | | | | | | | | | | | | | This patch removed obscure restriction on the HW setting of DMA transfers. Before this change each transaction sent up to 512 bytes (with packet count equal to 1) for non EP0 transfer. Now it is possible to setup DMA transaction up to DMA_BUFFER_SIZE.

* usb:udc:samsung: Remove redundant cache operation from Samsung UDC driverLukasz Majewski2014-02-06-17/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A set of cache operations (both invalidation and flush) were redundant in the S3C HS OTG Samsung driver: 1. s3c_udc_ep0_zlp - to transmit EP0's ZLP packets one don't need to flush the cache (since it is the zero length transmission) 2. s3c_udc_pre_setup and s3c_ep0_complete_out - cache invalidation is not needed when the buffer for OUT EP0 transmission is setup, since no data has yet arrived. Cache cleanups presented above don't contribute much to transmission speed up, hence shall be regarded as cosmetic changes. 3. setdma_rx - here the s3c UDC driver's internal buffers were invalidated. This call is not needed anymore since we reuse the buffers passed from gadgets. This is a key contribution to transmission speed improvement. Test condition - test HW + measurement: Trats - Exynos4210 rev.1 - test HW Trats2 - Exynos4412 rev.1 400 MiB compressed rootfs image download with `thor 0 mmc 0` Measurements: Base values (without improvement): Transmission speed: 9.51 MiB/s After the change: Transmission speed: 10.15 MiB/s Signed-off-by: Lukasz Majewski <l.majewski@samsung.com> Cc: Marek Vasut <marex@denx.de>

* usb: gadget: fotg210: EP0 fifo empty indication is non-reliableKuo-Jung Su2014-01-13-0/+1
| | | | | | | | | | | | | | | | | | The fifo size of ep0 is 64 bytes, and if the packet size grater than 64 bytes, the driver would have to fill up the fifo multiple times, and before filling up the fifo, the driver should make sure the fifo is empty by checking fifo empty indication. However there is a hardware bug that the fifo empty indication is somehow a bit earlier than fifo reset. So if I don't add an extra delay here, the data might be corrupted. (i.e., 1 byte missing) After a couple of tests, it truns out that 1 usec is good enough. This workaround should be applied to all hardware revisions.

* usb: gadget: fotg210: add w1c interrupt status supportKuo-Jung Su2014-01-13-0/+14
| | | | | | | | | | | | | | Since hardware revision 1.11.0, the following interrupt status registers are now W1C (i.e., write 1 clear): 1. Interrupt Source Group 0 Register (0x144) (EP0 Abort: BIT5) 2. Interrupt Source Group 2 Register (0x14C) (All bits) And before revision 1.11.0, these registers are all R/W. Which means software must write a 0 to clear the status. Signed-off-by: Kuo-Jung Su <dantesu@faraday-tech.com> CC: Marek Vasut <marex@denx.de>

* usb: dfu: f_dfu: Provide infrastructure to adjust DFU's Poll Timeout valueLukasz Majewski2013-12-18-3/+38
| | | | | | | | | | | It is necessary to deter the host from sending subsequent DFU_GETSTATUS request in the case of e.g. writing the buffer to medium. Here the timeout is increased when we fill up the whole buffer. This delay allows eMMC memory to perform its internal operations. Otherwise we end up with HOST's error regarding GET_STATUS receive timeout. Signed-off-by: Lukasz Majewski <l.majewski@samsung.com>

* usb: gadget: ether set wMaxPacketSizeTroy Kisky2013-10-20-0/+2
| | | | | | | | | | | | | | | | | | | | | set wMaxPacketSize for full speed descriptors fs_source_desc, fs_sink_desc to 64. Full-speed bulk endpoint can have a maximum packet size of 8, 16, 32, or 64 bytes, so choice 64. The hs_source_desc, hs_sink_desc, already have their wMaxPacketSize set to 512. That is the only legal value for high speed bulk endpoints. Strictly speaking, this patch is not needed because usb_ep_autoconfig will call ep_matches which will override wMaxPacketSize for BULK endpoints only with the size associated with the endpoint setup by the udc driver. But if you want to rely on this, you may as well combine the full speed descriptor with the high speed descriptor to minimize confusion. Signed-off-by: Troy Kisky <troy.kisky@boundarydevices.com>
