Gentle ping on this one... I'd really like to remove [devm_]gpiod_get_from_of_node() API from 6.2. Thanks.

There are more important fixes and less important cleanups for this aardvark driver which are waiting in the queue for longer time: https://patchwork.kernel.org/project/linux-pci/list/?series=&submitter=&state=&q=aardvark&archive=&delegate=

Thank you Bjorn! I wonder if you could also consider picking up the mvebu patch: https://lore.kernel.org/all/Y3KbhIi4ZsSO7+Cl@google.com/ pci-mvebu.c is the very last user of of_get_named_gpio_flags() in the next tree, which we also want to stop exporting. Thanks.

Sure, but the 0-day bot found a couple issues, which I haven't bothered to look into: https://lore.kernel.org/all/202211151503.HLlq2Z4B-lkp@intel.com/ Bjorn

I sent out v3 tha compiles cleanly. Thanks.

I'm disappointed that such unimportant change is prioritized and taken before any other important changes which are fixing real issue and waiting for applying about half of year. > > --- > > > > v2: > > - collected reviewed-by/acked-by tags > > - updated commit description to remove incorrect assumption of why > > devm_gpiod_get_from_of_node() was used in the first place > > > > This is the last user of devm_gpiod_get_from_of_node() in the mainline > > (next), it would be great to have it in so that we can remove the API in > > the next release cycle. > > > > Thanks! > > > > > > drivers/pci/controller/pci-aardvark.c | 23 +++++++++++------------ > > 1 file changed, 11 insertions(+), 12 deletions(-) > > > > diff --git a/drivers/pci/controller/pci-aardvark.c b/drivers/pci/controller/pci-aardvark.c > > index ba36bbc5897d..5ecfac23c9fc 100644 > > --- a/drivers/pci/controller/pci-aardvark.c > > +++ b/drivers/pci/controller/pci-aardvark.c > > @@ -1859,20 +1859,19 @@ static int advk_pcie_probe(struct platform_device *pdev) > > return ret; > > } > > > > - pcie->reset_gpio = devm_gpiod_get_from_of_node(dev, dev->of_node, > > - "reset-gpios", 0, > > - GPIOD_OUT_LOW, > > - "pcie1-reset"); > > + pcie->reset_gpio = devm_gpiod_get_optional(dev, "reset", GPIOD_OUT_LOW); > > ret = PTR_ERR_OR_ZERO(pcie->reset_gpio); > > if (ret) { > > - if (ret == -ENOENT) { > > - pcie->reset_gpio = NULL; > > - } else { > > - if (ret != -EPROBE_DEFER) > > - dev_err(dev, "Failed to get reset-gpio: %i\n", > > - ret); > > - return ret; > > - } > > + if (ret != -EPROBE_DEFER) > > + dev_err(dev, "Failed to get reset-gpio: %i\n", > > + ret); > > + return ret; > > + } > > + > > + ret = gpiod_set_consumer_name(pcie->reset_gpio, "pcie1-reset"); > > + if (ret) { > > + dev_err(dev, "Failed to set reset gpio name: %d\n", ret); > > + return ret; > > } > > > > ret = of_pci_get_max_link_speed(dev->of_node); > > -- > > 2.38.1.431.g37b22c650d-goog > > > > > > -- > > Dmitry > > > > _______________________________________________ > > linux-arm-kernel mailing list > > linux-arm-kernel@lists.infradead.org > > http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
