From 75fe4d48f81e03ff4201df164990cb85eb3084bc Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Noralf=20Tr=C3=B8nnes?= Date: Fri, 26 Jun 2015 14:25:01 +0200 Subject: [PATCH 0100/1085] firmware: bcm2835: Support ARCH_BCM270x MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Support booting without Device Tree. Turn on USB power. Load driver early because of lacking support for deferred probing in many drivers. Signed-off-by: Noralf Trønnes firmware: bcm2835: Don't turn on USB power The raspberrypi-power driver is now used to turn on USB power.
