[Marcel Ziswiler]

This series addresses various issues as seen on Colibri T20. Please
note that for successful Ethernet operation not only on Colibri T20
but also on Colibri T30 the following patch will still be required
already waiting in Marek's usb tree:

[PATCH v2] net: asix: Fix ASIX 88772B with driver model

https://www.mail-archive.com/u-boot@lists.denx.de/msg224349.html

Changes in v4:
- Use full regulator rather than reg wording again in debug message as
  suggested by Przemyslaw.
- Tighten up error handling as suggested by John.
- Fix set_enable() as suggested by Stephen.
- Add Stephen's ack.

Changes in v3:
- Add Stephen's ack.
- Introduce new patch to honour optionality of fixed regulator enable
  GPIO.
- Get rid of dummy N/C GPIO work around now as the fixed regulator
  properly honours optionality of enable GPIO.
- Add Stephen's ack.

Changes in v2:
- As suggested by Stephen gating the CONFIG_CI_UDC_HAS_HOSTPC define
  with CONFIG_TEGRA20 rather than duplicating the same into all other
  SoC type specific header files.
- Add Anatolij's ack.
- Rename dummy regulator to reg_3v3 as suggested by Stephen.
- Keep dummy N/C GPIO to work around bug in U-Boot regulator driver
  requiring such node despite its binding claiming it being optional.
- As suggested by Stephen remove last patch 5/5 colibri_t20: enable dfu
  also for nand.
