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.
