From 768716f4af35ee7b60bc70b7273e2a8c8c57342f Mon Sep 17 00:00:00 2001 From: Michael Heimpold Date: Thu, 9 Feb 2017 08:42:44 +0100 Subject: [PATCH] ARM: dts: imx28-duckbill: update to match vendor distributed DT This patch updates the Duckbill device tree and synchronize it with the vendor distributed file. The changes in mostly pin-muxing stuff, but also some minor fixes. In detail: - enable SPI pins - enable I2C pins - enable UART pins - enable LRADC pin - adjust USB DR mode - add default triggers for LEDs - get rid of regulators simple-bus container - adjust phy reset duration According to phy datasheet, 25ms are sufficient. This also reduces the time to boot the system.
