Subject: ARM: tegra: clamp inputs on Jetson TK1
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=4ff213b8e478ee06feaee3505b4228163661bd3f;p=u-boot.git

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.
