X-Git-Url: http://git.dujemihanovic.xyz/login.html?a=commitdiff_plain;h=274fb461f4792431b3777874472c8bd6149e6168;p=u-boot.git

dm: led: add testcase for "default-state" property

Add two more gpio-leds to sandbox test device tree with default-state
property set to "on"/"off".
Add dm_test_led_default_state() to check that these new LED's are set to
LEDST_ON and LEDST_OFF.
