[V3,0/2] pinctrl: bcm2835: Implement pin_conf_get

Message

For years, the Raspberry Pi users relied on userspace programs to read
the pin configuration. In the meantime, it has become apparent that this
approach has reached its limits for various reasons.

This patch series now attempts to improve the debugging possibilities on
the kernel side in order to reduce the dependency on these userspace
programs.

Changes in V3:
- convert changes to single return point of success as suggested by
  Andy Shevchenko
- justify ENOTSUPP checkpatch false positive

Changes in V2:
- adjust the BCM2711/7211 pull resistor value according to the Broadcom
  datasheet
