This series switches phy drivers form using fwnode_get_named_gpiod() and
gpiod_get_from_of_node() that are scheduled to be removed in favor
of fwnode_gpiod_get_index() that behaves more like standard
gpiod_get_index() and will potentially handle secondary software
nodes in cases we need to augment platform firmware.
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.

I see that the patches are marked as "Not applicable" in the netdev patchwork. Does this mean that you decided against pulling this immutable branch, or you dropped them because of kbuild complaints (that happened because it could not figure out how to apply the patches)?

I can't, because the dependencies don't exist in my tree. So submit this into the tree that will have the dependencies. ^ permalink raw reply [flat|nested] 12+ messages in thread

Argh, Gmail decided to stuff your original ACK and this reply in spam so I completely missed it and just fished them out of my spam folder, sorry about that. OK, I'll add your ACKs and forward to Linus Walleij then. I should have had him on the original emails... Thanks! -- Dmitry ^ permalink raw reply [flat|nested] 12+ messages in thread
