* TI PHY: Add support to control 2nd USB PHY in DRA7xx/AM57xxKishon Vijay Abraham I2015-08-28-4/+11
| | | | | | | | Added support to power on/power off the second USB PHY present in DRA7xx and AM57xx. Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com> Reviewed-by: Tom Rini <trini@konsulko.com>
* usb: dwc3: dwc3-omap: Use the clear register inorder to clear the interruptsKishon Vijay Abraham I2015-08-28-18/+28
| | | | | | | | | | Writing "0x00" to the USBOTGSS_IRQENABLE_SET_MISC and USBOTGSS_IRQENABLE_SET_0 doesn't disable the interrupts. Used USBOTGSS_IRQENABLE_CLR_MISC and USBOTGSS_IRQENABLE_CLR_0 instead.

* samsung: usb: phy: Support for DWC3 PHYLukasz Majewski2015-06-08-0/+79
| | | | | | | | | | | New files, namely samsung_usb_phy.c and samsung-usb-phy-uboot.h have been added to u-boot to provide proper PHY handling at Exynos5 SoCs. This code is used thereafter in the board_usb_init() call. Signed-off-by: Lukasz Majewski <l.majewski@samsung.com> Cc: Minkyu Kang <mk7.kang@samsung.com> Cc: Marek Vasut <marex@denx.de>
* usb: dwc3: Correct clean up code for requestsLukasz Majewski2015-04-14-24/+14
| | | | | | | | | | | | | | | | For u-boot dwc3 driver the scatter gather list support has been removed from original linux code. It is correct, since we try to send one request at a time. However, the cleanup left spurious break, which caused early exit from loop at dwc3_cleanup_done_reqs() function. As a result the dwc3_gadget_giveback() wasn't called and caused USB Mass Storage to hang. This commit removes this problem and refactor the code to remove superfluous do { } while(1) loop. Test HW: Odroid XU3 (with ./test/ums/ums_gadget_test.sh) Signed-off-by: Lukasz Majewski <l.majewski@samsung.com>
* usb: dwc3: gadget: Set non EP0 max packet limit to 512BLukasz Majewski2015-04-14-1/+1
| | | | | | | | | | Commit "drivers/dwc3: add a workaround for too small OUT requests" sets max packet for OUT requests when transfer is smaller. Until this change the default maxpacket for non EP0 EPs was 1024. This is too much, since UMS LBA size is 512B Signed-off-by: Lukasz Majewski <l.majewski@samsung.com>
* usb: dwc3: gadget: Set all ctrl fields of Transfer Control Blocks (TRB) to ↵Lukasz Majewski2015-04-14-13/+2
| | | | | | | | | | | | | | | | | be LST It turned out that current dwc3 gadget code is preparing multiple TRBs for a transfer. Unfortunately, when multiple requests are in the same queue, only for the last one the LST (last) ctrl bit is set. Due to that dwc3 HW executes all TRBs up till the one marked as last. Unfortunately, UMS requires call of ->complete callback after any send TRB. This is the reason for "hangs" in executing UMS. This code simplifies this situation and set each TRB's ctrl field bit to be last (LST bit). Signed-off-by: Lukasz Majewski <l.majewski@samsung.com>
* usb: dwc3: optimize interrupt loopMarek Szyprowski2015-04-14-9/+13
| | | | | | | | There is no point in calling dwc3_thread_interrupt() if no event is pending. There is also no point in flushing event cache in EVERY loop iteration. Signed-off-by: Marek Szyprowski <m.szyprowski@samsung.com>
* usb: dwc3: add a workaround for too small OUT requestsMarek Szyprowski2015-04-14-0/+8
| | | | | | | DWC3 hangs on OUT requests smaller than maxpacket size, so HACK the request length to be at least equal to maxpacket size. Signed-off-by: Marek Szyprowski <m.szyprowski@samsung.com>
