2020-04-13usb: Migrate to support live DT for some driverKever Yang
Use ofnode_ instead of fdt_ APIs so that the drivers can support live DT. This patch updates usb_get_dr_mode() and usb_get_maximum_speed() to use ofnode as parameter instead of fdt offset. And all the drivers who use these APIs update to use live dt APIs at the same time. Signed-off-by: Kever Yang <kever.yang@rock-chips.com>

2020-04-09usb: Keep async schedule running only across mass storage xfersMarek Vasut
Rather than keeping the asynchronous schedule running always, keep it running only across USB mass storage transfers for now, as it seems that keeping it running all the time interferes with certain control transfers during device enumeration. Note that running the async schedule all the time should not be an issue, especially on EHCI HCD, as that one implements most of the transfers using async schedule. Note that we have usb_disable_asynch(), which however is utterly broken. The usb_disable_asynch() blocks the USB core from doing async transfers by setting a global flag. The async schedule should however be disabled per USB controller. Moreover, setting a global flag does not prevent the controller from using the async schedule, which e.g. the EHCI HCD does. This patch implements additional callback to the controller, which permits it to lock the async schedule and keep it running across multiple transfers. Once the schedule is unlocked, it must also be disabled. This thus prevents the async schedule from running outside of the USB mass storage transfers.

2020-02-05dm: core: Create a new header file for 'compat' featuresSimon Glass
At present dm/device.h includes the linux-compatible features. This requires including linux/compat.h which in turn includes a lot of headers. One of these is malloc.h which we thus end up including in every file in U-Boot. Apart from the inefficiency of this, it is problematic for sandbox which needs to use the system malloc() in some files. Move the compatibility features into a separate header file.

2020-02-05dm: core: Require users of devres to include the headerSimon Glass
At present devres.h is included in all files that include dm.h but few make use of it. Also this pulls in linux/compat which adds several more headers. Drop the automatic inclusion and require files to include devres themselves. This provides a good indication of which files use devres.

2019-10-31usb: ehci-hcd: Keep async schedule runningMarek Vasut
Profiling the EHCI driver shows a significant performance problem in ehci_submit_async(). Specifically, this function keeps enabling and disabling async schedule back and forth for every single transaction. However, enabling/disabling the async schedule does not take effect immediatelly, but instead may take up to 1 mS (8 uFrames) to complete. This impacts USB storage significantly, esp. since the recent reduction of maximum transfer size to support more USB storage devices. This in turn results in sharp increase in the number of ehci_submit_async() calls. Since one USB storage BBB transfer does three such calls and the maximum transfer size is 120 kiB, the overhead is 6 mS per 120 kiB, which is unacceptable. However, this overhead can be removed simply by keeping the async schedule running. Specifically, the first transfer starts the async schedule and then each and every subsequent transfer only adds a new QH into that schedule, waits until the QH is completed and does NOT disable the async schedule. The async schedule is stopped only by shutting down the controller, which must happen before moving out of U-Boot, otherwise the controller will corrupt memory.

2019-10-24usb: ehci-mx6: Fix bus enumeration for iMX7 SoCsIgor Opaniuk
This fixes the issues with calculation of controller indexes in ehci_usb_bind() for iMX7, as USB controllers on iMX7 SoCs aren't placed next to each other, and their addresses incremented by 0x10000. Example of USB nodes for iMX7S/D: usbotg1: usb@30b10000 { compatible = "fsl,imx7d-usb", "fsl,imx27-usb"; reg = <0x30b10000 0x200>; ^^^^^^^^^^ .... usbotg2: usb@30b20000 { compatible = "fsl,imx7d-usb", "fsl,imx27-usb"; reg = <0x30b20000 0x200>; ^^^^^^^^^^ .... usbh: usb@30b30000 { compatible = "fsl,imx7d-usb", "fsl,imx27-usb"; reg = <0x30b30000 0x200>; ^^^^^^^^^^ .... Which was leading to usb enumeration issues: Colibri iMX7 # usb start starting USB...

2019-07-05usb: ehci-mx6: Fix bus enumeration for DM caseMarek Vasut
The EHCI iMX6 driver is only partly converted to DT probing and still uses a tremendous amount of hard-coded addresses. Worse, the driver uses hard-coded SoC-model-specific base addresses, which are derived from values protected by SoC-specific macros, hence the driver is also compiled for a specific SoC model. Even worse, the driver depends on specific sequential indexing of the controllers, from which it derives offsets in the PHY and ANATOP register sets. However, when the driver is probed from DT, the indexing is not correct. In fact, each controller has index 0. This patch derives the index for DT probing case from the controller base addresses, which is not the way this should be done, however it is the least intrusive approach, favorable this close to release. The necessary steps to convert this driver fully to DT probing are described inside the patch, however this should be done in the next release and depends on iMX clock driver patches.
