[U-Boot] [PATCH 0/14] dm: omap: Provide access to driver model for am335x, and move boards

[Simon Glass]

This series adjusts the serial and GPIO drivers, used by Beaglebone for
example, to work with driver model. Since there are still boards using
these drivers but not driver model, this adds new functionality rather
than replacing what exists.

Several patches tweak and fix the existing driver model serial and GPIO
implementation.

There are two Beaglebone Black configurations:

- Device tree control with verified boot
- No device tree control

The first uses device tree to select the serial console and provide
information needed by the serial driver (similar to how things work on
Tegra). The second uses platform data provided by a common board file.

Both are converted, so this is a good example of how to support both device
tree and platform data if needed.


Simon Glass (14):
  dm: gpio: Support numbered GPIOs
  dm: serial: Reset the watchdog while waiting in getc()
  dm: serial: ns16550: Correct logic for checking for character
  dm: ns16550: Use an address instead of a pointer for the uart base
  dm: ns16550: Correct the probe logic for platform data
  dm: serial: Support CONFIG_CONS_INDEX if available
  dm: dts: omap: Select correct console for beaglebone
  dm: omap: gpio: Put _get_gpio_value() logic into its own function
  dm: omap: gpio: Support driver model
  dm: am33xx: Provide platform data for GPIOs
  dm: am33xx: Provide platform data for serial
  dm: omap: serial: Add driver model support
  dm: am335x: Remove serial options from CONFIG_SYS_EXTRA_OPTIONS
  dm: am33xx: Move to driver model for GPIO and serial
