From a96e8808854cceefab45a7b71152ccebf3ba6cdf Mon Sep 17 00:00:00 2001 From: Grygorii Strashko Date: Thu, 27 Aug 2015 18:20:46 +0300 Subject: [PATCH] ARM: dts: dra7-evm: add gpio leds support dra7-evm has 4 user gpio leds connected to PCF8575 GPIO pcf_lcd: gpio@20 expander pins [4,5,6,7], so add corresponding DT nodes. Do not enable any triggers by default as not all of them are proved to work on -RT.
