[PATCH 0/4] Support UART over MicroSD slot on Transformer T20

[Artur Kowalski]

The first patch in the series brings general pinmux support for exposing
UART over SDB/SDD pins on T20. The following patches bring support
Transformer T20 allowing to enable UART over uSD by setting

CONFIG_TEGRA_ENABLE_UARTA=y
CONFIG_DEVICE_TREE_INCLUDES="tegra20-asus-transformer-uart-usd.dtsi"

Similarily, support for UART over uSD could be brought to Ventana which
has uSD on the same pins as TF101, and other Ventana-based boards.


Artur Kowalski (4):
  tegra: add funcmux for exposing UART over uSD slot on Tegra 20
  tegra: respect CONFIG_TEGRA_ENABLE_UART* options on Transformer T20
  ARM: tegra: expose UART-A over uSD on Transformer T20
  board: asus: transformer: add DTSI file for enabling UART over uSD
    slot
