Subject: [PATCH] drm/bridge: ti-tfp410: switch to using
 fwnode_gpiod_get_index()

Instead of fwnode_get_named_gpiod() that I plan to hide away, let's use
the new fwnode_gpiod_get_index() that mimics gpiod_get_index(), but
works with arbitrary firmware node.

Andrzej, Neil,

This depends on the new code that can be bound in
ib-fwnode-gpiod-get-index immutable branch of Linus' Walleij tree:

        git pull git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio.git ib-fwnode-gpiod-get-index

I hope that it would be possible to pull in this immutable branch and
not wait until after 5.5 merge window, or, alternatively, merge through
Linus Walleij's tree.

Thanks!
