Subject: [PATCH 0/4] arm64: tegra: Small hardware enablement for Jetson TX1

This series consists of Device Tree changes enabling two features:
 - Using both TCA9539 GPIO expanders found on P2597 as IRQ controllers
 - TMP451 temperature sensor found on P2180

For the first feature some preparation is needed:
 - Patch 01: fix the enable GPIO line number for a regulator, freeing an
   	     exposed line on P2597 expansion header J21
 - Patch 02: add voltage level pinctrl information
 - Patch 03: fill the TCA9539 DT nodes for IRQ controller operation

Patch 04 simply adds the TMP451 node to the Device Tree of the P2180
module.
