[PATCH v7 0/3] ARM: omap1: use real firmware node lookup for GPIOs on Nokia 770

[Bartosz Golaszewski]

This converts Nokia 770 to using real firmware node lookup for GPIOs by
attaching the software nodes describing GPIO controllers to their target
devices.

Changes in v7:
- Drop ADS7846_PENDOWN_GPIO define from patch 3/3, move the value to the
  property entry
- Convert the second dev_err() to pr_err()
- Add the device name.id in the pr_err() output
- Collect tags
- Link to v6: https://patch.msgid.link/20260427-nokia770-gpio-swnodes-v6-0-b693296c1985@oss.qualcomm.com

Changes in v6:
- Switch to using platform_device_register_full() and pass the software
  node via the swnode field of struct platform_device_info
- Drop driver-core prerequisites from the series
- Rebase on top of v7.1-rc1
- Add patch dropping an unused variable
- Link to v5: https://patch.msgid.link/20260402-nokia770-gpio-swnodes-v5-0-d730db3dd299@oss.qualcomm.com

Changes in v5:
