* usb: imx: role_registered contains roleSascha Hauer2017-03-091-2/+2
| | | | | | | role_registered contains the role, it's not a bool indicating that a role is registered. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* usb: imx: Make usb-misc multi instance safeSascha Hauer2017-01-191-2/+7
| | | | | | | i.MX7 has two usbmisc devices, so we cannot use global instance variables anymore. Create a driver private data struct for it. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* usb: imx-us-phy: Convert driver to generic phy supportSascha Hauer2016-09-291-0/+21
| | | | | | | The generic phy layer now supports USB phys, so convert the driver over to use it. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* usb: i.MX chipidea: Enable VBUS regulator when neededSascha Hauer2016-09-051-4/+13
| | | | | | | We should enable VBUS only in host mode, not unconditionally during probe(). Fix that. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* usb: chipidea i.MX: Do not return unnecessary errorSascha Hauer2016-08-291-3/+8
| | | | | | | | | We only allow to setup the host/peripheral role once, when it's already set then we return -EBUSY. Return 0 instead when we set the same role again and only return -EBUSY when we actually try to change the role. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* driver: replace dev_request_mem_region with dev_request_mem_resourceSascha Hauer2016-03-071-3/+5

Replace them with dev_request_mem_resource where possible.

* usb: chipidea-imx: check return value of regulator_get()David Jander2016-01-081-1/+2

| * usb: chipidea: Add udc unregister for device removalMarkus Pargmann2015-09-231-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | The host may assume that the usb device is still up and running after booting if we do not deregister the udc here. I observed issues when the linux kernel was using a usb gadget directly where the complete USB Hub got disconnected through this. This patch adds a proper USB disconnect for gadget devices.

* USB i.MX: Add chipidea driver supportSascha Hauer2012-12-131-0/+91
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. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
