    Subject[PATCH 5.4 162/453] ARM: dts: at91: sama5d3_xplained: add pincontrol for USB Host
    Date
    From: Cristian Birsan <cristian.birsan@microchip.com>

    [ Upstream commit e1062fa7292f1e3744db0a487c4ac0109e09b03d ]

    The pincontrol node is needed for USB Host since Linux v5.7-rc1. Without
    it the driver probes but VBus is not powered because of wrong pincontrol
    configuration.

    Fixes: b7c2b61570798 ("ARM: at91: add Atmel's SAMA5D3 Xplained board")
