Subject: [PATCH v4 6/6] usb: ohci-da8xx: drop the vbus GPIO
Date: Thu, 11 Apr 2019 11:30:24 +0200	[thread overview]
Message-ID: <20190411093024.23555-7-brgl@bgdev.pl> (raw)
In-Reply-To: <20190411093024.23555-1-brgl@bgdev.pl>

From: Bartosz Golaszewski <bgolaszewski@baylibre.com>

All users now setup a fixed regulator for the vbus supply. We can drop
the vbus GPIO code.
