e7a95ee2b5 pinctrl: Tighten some pinctrl driver dependencies
A few pinctrl drivers cannot build without access to some platform
specific header files. Express those requirements in Kconfig as well.

427dd4dd27 ARM: tegra20: add funcmux for exposing UART over uSD slot on Tegra 20
UART-A can be exposed through uSD, this was tested on Transformer T20
but should work on all Ventana-based boards.

TX is exported on SDD pingroup corresponding to uSD CLK pin
RX is exported on SDB which is CMD pin in uSD slot

a35bf832d7 pinctrl: tegra20: detect unknown/invalid pin/func configurations
Tegra20 driver doesn't know about some pin configurations and even about
some pins. In case when pin configuration is unknown the pin would be
muxed to whatever is under function 0, in case when pin itself is
unknown, it could cause out-of-bounds array access in pinmux_set_func
and pinmux_set_pullupdown.

59bc308221 pinctrl: tegra: adjust default values of pins
The current default pin and drive values were more of temporary
placeholders. They have to be replaced with accurate default values as
specified in the TRM and header file.

efb7964cc1 pinctrl: tegra20: adjust pin type detection
Pin detection on t20 depends on node name. With recent changes
in node naming, let's remove '_' to be safe about both '_' or
'-' use.

b515d7ae0d Tegra30: Add funcmux for UART over SD slot
Tegra 3 has UART-E exposable via SD card slot which may be
handy for debugging. This change only adds funcmux part, to
use UART-E on the device you additionally would need:
- set stdout-path to serial@70006400 (uarte)
- configure sdmmc1_dat3_py4 and sdmmc1_dat2_py5 pinmux for
  uarte
- disable or remove sdhci@7800000 node
- enable CONFIG_TEGRA_ENABLE_UARTE in defconfig
- set CFG_SYS_NS16550_COM to NV_PA_APB_UARTE_BASE in device
  header

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.

This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing
changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

91069320a5 drivers: pinctrl: create Tegra DM pinctrl driver
The existing pinctrl driver available for Tegra SOC is well
designed, but it lacks DM support. Let's add a DM compatible
overlay, which allows use of the device tree, along with preserving
backward compatibility with all existing setups and the ability
to use it in SPL board configuration stage.
