2017-02-08dm: core: Replace of_offset with accessorSimon Glass
At present devices use a simple integer offset to record the device tree node associated with the device. In preparation for supporting a live device tree, which uses a node pointer instead, refactor existing code to access this field through an inline function.

2016-09-18sunxi: musb: Re-init musb controller on repeated probe callsHans de Goede
With sunxi-musb musb_lowlevel_init() can fail when a charger; or no cable is plugged into the otg port. To avoid leaking the struct musb allocated by musb_init_controller() on repeated musb_usb_probe() calls, we were caching its result. But musb_init_controller() does more, such as calling sunxi_musb_init() which enables the clocks. Not calling sunxi_musb_init() causes the musb controller to stop working after a "usb reset" since that calls musb_usb_remove() which disables the clocks. This commit fixes this by removing the caching of the struct returned from musb_init_controller(), it replaces this by free-ing the allocated memory in musb_usb_remove() and calling musb_usb_remove() on musb_usb_probe() errors to ensure proper cleanup. While at it also make musb_usb_probe() and musb_usb_remove() static. Signed-off-by: Hans de Goede <hdegoede@redhat.com>

The Linux kernel musb driver expects VBUS to be off while initializing musb. Having it on results in a repeating string of warnings, followed by an unusable peripheral.

2015-12-31usb: musb: Fix hub port setting for SPLIT transactionsStefan Brüns
The ifdef'ed Linux kernel code uses the 1 based port number, whereas U-Boot puts a 0 based port number into the register. The reason the 0 based port number apparently works can probably be taken from the USB 2.0 spec: 8.4.2.2 Start-Split Transaction Token ... The host must correctly set the port field for single and multiple TT hub implementations. A single TT hub implementation *may ignore* the port field. Actually, as far as I understand, a multi TT hub defaults to single TT (bAlternateSetting: 0) until switched via SetInterface, so even "port 42" would work. The change was verified by hardcoding the port number to a wrong value, SPLIT transactions kept working (although using a DWC2 instead of MUSB). Tested hubs are the RPi onboard SMC9514 and an external "05e3:0608 Genesys Logic, Inc. USB-2.0 4-Port HUB". The former is a multi TT hub, the latter single TT only.

2015-08-08sunxi: usb-phy: Never power off the usb portsHans de Goede
USB devices are not really designed to get the power bounced off and on at them. Esp. USB powered harddisks do not like this. Currently we power off the USB ports both on a "usb reset" and when booting the kernel, causing the usb-power to bounce off and then back on again. This patch removes the powering off calls, fixing the undesirable power bouncing. Note this requires some special handling for the OTG port: 1) We must skip the external vbus check if we've already enabled our own vbus to avoid false positives 2) If on an usb reset we no longer detect that the id-pin is grounded, turn off vbus as that means an external vbus may be present now Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>

So once we've moved all the sunxi usb code to the driver-model then phy_probe will be called once for the entire block from the driver-model enumeration code. Move to this now as this also avoids problems with phy_probe being called multiple times once we introduce ohci support. This also allows us to get rid of the sunxi_usb_phy_enabled_count variable as phy_probe now is guaranteed to be called only once. Since we're effectively rewriting the probe / remove functions, move them to the end of the file while we are at it, as that is the most logical place for them.
