* dm: pci: Add a uclass for PCISimon Glass2015-04-16-4/+714
| | | | | | | | | | | Add a uclass for PCI controllers and a generic one for PCI devices. Adjust the 'pci' command and the existing PCI support to work with this new uclass. Keep most of the compatibility code in a separate file so that it can be removed one day. TODO: Add more header file comments to the new parts of pci.h Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: pci: Move common PCI functions into their own fileSimon Glass2015-04-16-276/+299
| | | | | | | Driver model will share many functions with the existing PCI implementation. Move these into their own file to avoid duplication and confusion. Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: core: Add a uclass pre_probe() method for devicesSimon Glass2015-04-16-2/+10
| | | | | | | | | | | | Some uclasses want to set up a device before it is probed. Add a method for this. An example is with PCI, where a PCI uclass wants to set up its private data for later use. This allows the device's uclass() method to make calls whcih use that data (for example, read PCI memory regions from device tree, set up bus numbers). Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: core: Mark device as active before calling its probe() methodSimon Glass2015-04-16-3/+4
| | | | | | | | | | | | | | | | | | At present the device is not active when the probe() method is called. But some probe() methods want to set up the device and this can involve accessing it through normal methods. For example a PCI bus may wish to set up its PCI parameters using calls to pci_hose_write_config_dword() and similar. At present this does not work because every such call within the probe() method sees that the device is not active and attempts to probe it. Already we mark the device as probed before calling the uclass post_probe() method. This is a subtle change but I believe the new approach is better. Since the scope of the change is only the probe() method and all its callees it should still be within the control of the board author. Signed-off-by: Simon Glass <sjg@chromium.org>

* x86: Add a x86_ prefix to the x86-specific PCI functionsSimon Glass2015-04-16-8/+8
| | | | | | | | | | | | These functions currently use a generic name, but they are for x86 only. This may introduce confusion and prevents U-Boot from using these names more widely. In fact it should be possible to remove these at some point and use generic functions, but for now, rename them.

* ti: dwc3: Enable clocks in enable_basic_clocks() in hw_data.cKishon Vijay Abraham I2015-04-16-16/+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>

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 Goede2015-04-15-1/+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: common VBUS detection logic in usbcPaul Kocialkowski2015-04-15-29/+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).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

The actual setting and checking of the reset flag should be implemented by a boot script and/or board/SoC specific code.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Majewski2015-04-14-13/+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>
