Subject: [PATCH 04/13] pinctrl: tegra: try to select "boot" state
Date: Sun, 2 Nov 2014 21:13:46 +0100 [thread overview]
Message-ID: <1414959235-18095-5-git-send-email-dev@lynxeye.de> (raw)
In-Reply-To: <1414959235-18095-1-git-send-email-dev@lynxeye.de>
New DTs call the initial pinctrl state "boot" in
order to avoid Linux reconfiguring the pinctrl
by default. The bootloader should explicitly set
this state.
