Subject: [PATCH 1/2] dt-bindings: gpio-xilinx: Update no-init property
Date: Thu, 3 May 2018 14:35:45 +0530	[thread overview]
Message-ID: <1525338346-31684-1-git-send-email-shubhrajyoti.datta@gmail.com> (raw)

From: Shubhrajyoti Datta <shubhrajyoti.datta@xilinx.com>

In some cases the user may not want to initialise the
gpios to default. Add a property to allow the same. This is specially
useful in case the PS is reset and PL is not.
