Subject: ARM: dts: dra7-evm: add gpio leds support
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=a96e8808854cceefab45a7b71152ccebf3ba6cdf;p=openwrt%2Fstaging%2Fblogic.git

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.
