[PATCH v2 7/7] arm: dts: qcom: db410c: Enable USB OTG support

The Dragonboard-410c is able to act either as USB Host or Device. The role can be determined at runtime via the USB_HS_ID pin which is derived from the micro-usb port VBUS pin. In Host role, SoC USB D+/D- are routed to the onboard USB 2.0 HUB. In Device role, SoC USB D+/D- are routed to the USB 2.

[PATCH v2 1/7] usb: chipidea: Add dynamic pinctrl selection

Some hardware implementations require to configure pins differently according to the USB role (host/device), this can be an update of the pins routing or a simple GPIO value change. This patch introduces new optional "host" and "device" pinctrls. If these pinctrls are defined by the device, they a

[PATCH v2 5/7] usb: chipidea: Fix otg event handler

At OTG work running time, it's possible that several events need to be addressed (e.g. ID and VBUS events). The current implementation handles only one event at a time which leads to ignoring the other one. Fix it. Signed-off-by: Loic Poulain --- v2: no change drivers/usb/chipidea/otg.c | 9 ++

[PATCH v2 6/7] phy: qcom-usb-hs: Fix unbalanced notifier registration

Phy power on/off cycle can happen several times during device life. We then need to balance the extcon notifier registration accordingly. Fixes: f0b5c2c96370 ("phy: qcom-usb-hs: Replace the extcon API") Signed-off-by: Loic Poulain --- v2: don't use devres version (power-on always followed by pow

[PATCH v2 4/7] usb: chipidea: Prevent unbalanced IRQ disable

The ChipIdea IRQ is disabled before scheduling the otg work and re-enabled on otg work completion. However if the job is already scheduled we have to undo the effect of disable_irq int order to balance the IRQ disable-depth value. Fixes: be6b0c1bd0be ("usb: chipidea: using one inline function to c

[PATCH v2 3/7] usb: chipidea: Support generic usb extcon

Add compatibility for extcon-usb-gpio which can handle more than one cable per instance, allowing coherency of USB cable states (USB/USB-HOST). These states can be generated from ID or/and VBUS pins. In case only one extcon device is associated to the USB device, and this device supports USB and U
