| * | USB i.MX: Add chipidea driver supportSascha Hauer2012-12-131-0/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For proper USB function the usbmisc registers have to be initialized. This patch adds a driver which matches for the usbmisc registers. This driver is called from a new driver which binds to the USB ports to configure the misc registers. After that the driver registers the EHCI driver and an ULPI transceiver if necessary. Currently only host mode is supported, but device support can be added later.

|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | dev_add_child is a very unsafe function.

This function is removed from the tree. Now callers of register_device have to clearly set the parent *before* registering a device.
