usb: chipidea: core: check before accessing ci_role in ci_role_show

2017-05-23T00:36:54Z

ci_role BUGs when the role is >= CI_ROLE_END. This is the case while the role is changing. Signed-off-by: Michael Thalmeier Signed-off-by: Peter Chen

usb: chipidea: properly handle host or gadget initialization failure

2017-05-18T00:55:22Z

If ci_hdrc_host_init() or ci_hdrc_gadget_init() returns error and the error != -ENXIO, as Peter pointed out, "it stands for initialization for host or gadget has failed", so we'd better return failure rather continue. And before destroying the otg, i.e ci_hdrc_otg_destroy(ci), we should also check ci->roles[CI_ROLE_GADGET]. Signed-off-by: Jisheng Zhang Signed-off-by: Peter Chen

Merge tag 'usb-ci-v4.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/peter.chen/usb into usb-next

usb: chipidea: core: add sysfs group

2017-04-14T01:26:37Z

Sometimes, the user needs to adjust some properties for controllers, eg the role for controller, we add sysfs group for them. The attribute 'role' is used to switch host/gadget role dynamically, the uewr can read the current role, and write the other role compare to current one to finish the switch.

usb: chipidea: use bus->sysdev for DMA configuration

2017-03-23T07:20:21Z

Set the dma for chipidea from sysdev. This is inherited from its parent node. Also, do not set dma mask for child as it is not required now.

usb: chipidea: Configure phy for appropriate mode

2017-02-03T08:48:33Z

When the qcom chipidea controller is used with an extcon, we need to signal device mode or host mode to the phy so it can configure itself for the correct mode. This should be done after the phy is powered up, so that the register writes work correctly. Add in the appropriate phy_set_mode() call here.

usb: chipidea: msm: Handle phy power states

2017-01-20T07:27:35Z

The ULPI phy on qcom platforms needs to be initialized and powered on after a USB reset and before we toggle the run/stop bit. Otherwise, the phy locks up and doesn't work properly. Hook the phy initialization into the RESET event and the phy power off into the STOPPED event. Acked-by: Peter Chen Cc: Greg Kroah-Hartman Signed-off-by: Stephen Boyd Signed-off-by: Peter Chen

usb: chipidea: Consolidate extcon notifiers

2017-01-20T07:13:49Z

The two extcon notifiers are almost the same except for the variable name for the cable structure and the id notifier inverts the cable->state logic. Make it the same and replace two functions with one to save some lines. This also makes it so that the id cable state is true when the id pin is pulled low, so we change the name of ->state to ->connected to properly reflect that we're interested in the cable being connected.
