[PATCH 1/1] gpio: tegra186: Set fwnode of the GPIO chip

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
