* ti: dwc3: Enable clocks in enable_basic_clocks() in hw_data.cKishon Vijay Abraham I2015-04-161-16/+0
| | | | | | | | | | | | | | | | Commit d3cfcb3 (ARM: DRA7: Enable clocks for USB OTGSS and USB PHY) changed the member names of prcm_regs from cm_l3init_usb_otg_ss_clkctrl to cm_l3init_usb_otg_ss1_clkctrl and from cm_coreaon_usb_phy_core_clkctrl to cm_coreaon_usb_phy1_core_clkctrl in order to differentiate between the two dwc3 controllers present in dra7xx/am43xx and enabled these clocks in enable_basic_clocks() in hw_data.c. However these clocks continued to be enabled in board files/driver files for dwc3 host mode functionality causing compilation break with few configs. Fixed it here by making all the clocks enabled in enable_basic_clocks() and removing it from board files/driver files here. Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com>

| * i2c: mvtwsi: Support for up to 4 different controllersPaul Kocialkowski2015-04-151-29/+99
| | | | | | | | | | | | | | | | | | | | | | | | Orion5x, Kirkwood and Armada XP platforms come with a single TWSI (I2C) MVTWSI controller. However, other platforms using MVTWSI may come with more: this is the case on Allwinner (sunxi) platforms, where up to 4 controllers can be found on the same chip.

| * sunxi: axp221: Use vbus-available rather then vbus-usable for vbus-detectHans de Goede2015-04-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | vbus-usable may not get set if power is provided through both the power barrel connector and external 5v is also present on the otg connector, at least on boards where vbus is also controlled through the axp221-pmic. One way to reproduce this is to bootup an Ippo-q8h board with a usb-host cable plugged into the otg (so that it will get powered), then unplug the usb-host cable and plug in a charger, and then do "reset" on the u-boot console, vbus-usable will then report 0, leading to uboot trying to provide power to the otg port even though external 5v is present, this commit fixes this.

| | | | | | | | | | | | | | | | | | | | | | | | | | Sunxi platforms have different possible mmc pin mux setups (except for mmc0), which are different across platforms. This lets users configure which is used through the CONFIG_MMC*_PINS Kconfig options. This is especially relevant when a second (in addition to mmc0) port is used and CONFIG_MMC_SUNXI_SLOT_EXTRA is enabled.

| | | | | | | | | | | | | | | | | | | | | | Each hardware feature exposed through the GPIO pin mux is usually using the same function index (for a given port), so there is no need to define one value per pin: one value per hardware feature per port is sufficient, avoids duplication and makes everything easier to understand.

| * sunxi: common VBUS detection logic in usbcPaul Kocialkowski2015-04-151-29/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | VBUS detection could be needed not only by the musb code (to prevent host mode), but also by e.g. gadget drivers to start only when a cable is connected. In addition, this allows more flexibility in vbus detection, as it could easily be extended to other USBC indexes. Eventually, this would help making musb support independent from a hardcoded USB controller index (0).

* | fastboot: add support for reboot-bootloader commandAlexey Firago2015-04-141-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The "fastboot reboot-bootloader" command is defined to re-enter into fastboot mode after rebooting into bootloader. This command is usually used after updating bootloader via fastboot. This commit implements only a generic side of the command - setting of the reset flag and then resetting. Setting of the reset flag is implemented using __weak fb_set_reboot_flag() function. The actual setting and checking of the reset flag should be implemented by a boot script and/or board/SoC specific code.

* | usb: dwc3: Correct clean up code for requestsLukasz Majewski2015-04-141-24/+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.

* | usb: dwc3: gadget: Set all ctrl fields of Transfer Control Blocks (TRB) to ↵Lukasz Majewski2015-04-141-13/+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>
