Subject: [PATCH 1/1] gpio: tegra186: Set fwnode of the GPIO chip
Any driver that depends on the GPIO match function to locate the GPIO
controller, it has to use the fwnode from the gpio_chip structure. But
with [1], it is GPIO providers job to set any members of the gpio_chip
structure. This patch addresses that.
