From 4ff213b8e478ee06feaee3505b4228163661bd3f Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Tue, 22 Apr 2014 14:37:56 -0600 Subject: ARM: tegra: clamp inputs on Jetson TK1 The HW-defined procedure for booting Tegra requires that CLAMP_INPUTS_WHEN_TRISTATED be enabled before programming the pinmux. Modify the Jetson TK1 board to do this.
