Subject: [PATCH v2 0/3] ARM: dts: lan966x: Extend pcb8291

Extend pcb8291 with different features like, add support to reset the board
using GPIO and add network support.

v1->v2:
- instead of removing the can0 node, just disable and add a comment
- reorder the nodes to be alphabetical

Horatiu Vultur (3):
ARM: dts: lan966x: Add gpio-restart
ARM: dts: lan966x: Disable can0 on pcb8291
ARM: dts: lan966x: Enable network driver on pcb8291
