PATCH 1/3 ARM: dts: at91: sama5d2 Xplained: set pin muxing for usb gadget and usb host

From: Cyrille Pitchen <[email protected]>

For USB gadget on port A (device mode):
- pin PA31 is configured as an input GPIO which triggers an interrupt when vbus is detected on USB port A.
- pin PB9 is configured as an output GPIO and set to low level so the board doesn't supply vbus to USB port A.

For USB host:
- pin PB10 is configured as an output GPIO and is active at high level. The ohci driver will activate this pin so the board supplies vbus to USB port B.
- pin PB9 should be configured as an output GPIO and active at high level to use to USB port A in host mode (conflicts with USB gadget).

PATCH 2/3 ARM: dts: at91: sama5d2 Xplained: add user push button

In reply to Nicolas Ferre

From: Ludovic Desroches <[email protected]>

Add the push button named "PB USER" with code 0x104. Associated pinctrl node is also added.

PATCH 3/3 ARM: dts: at91: sama5d2 Xplained: add leds node

In reply to Nicolas Ferre

From: Wenyou Yang <[email protected]>

Add the three leds on the sama5d2 Xplained board with their pinctrl node. The blue led is positioned with the "heartbeat" trigger.
