Subject: [PATCH] ARM: DTS: da850: fixed missing #gpio-cells in gpio node
Date: Tue, 5 Apr 2016 11:31:37 +0200 [thread overview]
Message-ID: <1459848697-21006-1-git-send-email-petr@barix.com> (raw)
The gpio node was missing the mandatory property #gpio-cells, which was
causing runtime errors when using GPIOs e.g. with gpio-leds or gpio-keys:
"could not get #gpio-cells for /soc/gpio@1e26000"
This fixes the problem and adds the missing parameter.
The value is 2 according to the gpio-davinci.txt binding.
