Subject: [PATCH] ARM: BCM5301X: Set vcc-gpio for USB controllers of few
devices
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
There are few devices that have USB power controlled using GPIO. Linux
USB host driver (bcma-hcd) already supports this by reading vcc-gpio
from DT. Set it properly for all known devices.
