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

Existing Tegra DSI driver mostly fits T114 apart MIPI calibration
which on T114 has dedicated driver. To resolve this MIPI calibration
logic was split for pre-T114 and T114+ devices.

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.

Adds support for both DSI outputs found on Tegra. Only very
minimal functionality is implemented, so advanced features
like ganged mode won't work. Driver is heavily based on
mainline Tegra DSI and re-uses much of its features.
Only T30 is supported for now but T20 support can be added
if any supported devices will be found.
Driver is wrapped as panel driver since Tegra DC driver supports
only panel drivers calls.

On popular request make the display driver from T20 work on T30 as
well. Turned out to be quite straight forward. However a few notes
about some things encountered during porting: Of course the T30 device
tree was completely missing host1x as well as PWM support but it turns
out this can simply be copied from T20. The only trouble compiling the
Tegra video driver for T30 had to do with some hard-coded PWM pin
muxing for T20 which is quite ugly anyway. On T30 this gets handled by
a board specific complete pin muxing table. The older Chromium U-Boot
2011.06 which to my knowledge was the only prior attempt at enabling a
display driver for T30 for whatever reason got some clocking stuff
mixed up. Turns out at least for a single display controller T20 and
T30 can be clocked quite similar. Enjoy.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

On currently supported SoCs, clk_m always runs at the same frequency as
the oscillator input. However newer SoC generations such as Tegra210 no
longer have that restriction. Prepare for that by separating clk_m from
the oscillator clock and allow SoC code to override the clk_m rate.

ARM: tegra: Use mem size from MC rather than ODMDATA
In addition to the move of using the Tegra memory controller (MC)
register rather than ODMDATA for T20, T30 and T114 as well it further
uses the generic get_ram_size() function (see "common/memsize.c")
<supposed to be used in each and every U-Boot port>TM. Added benefit is
that it should <catch 99% of hardware related (i. e. reliably

available which unfortunately does not include T114 and T124 (yet at
least) plus on the Jetson TK1.

arch/arm/include/asm/spl.h requires all SoCs to have
arch/arm/include/asm/arch-*/spl.h.
But many of them just define BOOT_DEVICE_* macros.
Those macros are used in the "switch (boot_device) { ... }"
statement in common/spl/spl.c.
So they should not be archtecture specific, but be described as
a simpile enumeration.
This commit merges most of arch/arm/include/asm/arch-*/spl.h
into arch/arm/include/asm/spl.h.
With a little more effort, arch-zynq/spl.h and arch-socfpga/spl.h
will be merged, while I am not sure about OMAP and Exynos.

Define enum PMUX_FUNC_DEFAULT, which indicates that a table entry passed
to pinmux_config_pingrp()/pinmux_config_pingrp_table() shouldn't change
the mux option in HW.
For pins that will be used as GPIOs, the mux option is irrelevant, so we
simply don't want to define any mux option in the pinmux initialization
table.

Use smaller fields in the Tegra pinmux structures in order to pack the
data tables into a smaller space. This saves around 1-3KB for the SPL
and around 3-8KB for the main build of U-Boot, depending on the board,
which SoC it uses, and how many pinmux table entries there are.
In order to pack PMUX_FUNC_* into a smaller space, don't hard-code the
values of PMUX_FUNC_RSVD* to values which require 16 bits to store them,
but instead let their values be assigned automatically, so they end up
fitting into 8 bits.

This renames all the pinmux pins, drive groups, and functions so they
have a prefix which matches the type name. These lists are also auto-
generated using scripts that were also used to generate the kernel
pinctrl drivers. This ensures that the lists are consistent between the
two.
The entries in tegra30_pingroups[] are all updated to remove the columns
which are no longer used.
All affected code is updated to match.
This introduces a few changes to pin/group/function naming and the set of
available functions for each pin. The new values now exactly match the
TRM; the chip documentation. I adjusted one entry in
pinmux-config-cardhu.h due to this.

Clean up the naming of pinmux-related objects:
* Refer to drive groups rather than pad groups to match the Linux kernel.
* Ensure all pinmux API types are prefixed with pmux_, values (defines)
are prefixed with PMUX_, and functions prefixed with pinmux_.
* Modify a few type names to make their content clearer.
* Minimal changes to SoC-specific .h/.c files are made so the code still
compiles. A separate per-SoC change will be made immediately following,
in order to keep individual patch size down.

Much of arch/arm/cpu/tegra*-common/pinmux.c is identical. Remove the
duplication by creating pinmux-common.c for all the identical code.
This leaves:
* arch/arm/include/asm/arch-tegra*/pinmux.h defining only the names of
the various pins/pin groups, drive groups, and mux functions.
* arch/arm/cpu/tegra*-common/pinmux.c containing only the lookup table
stating which pin groups support which mux functions.
The code in pinmux-common.c is semantically identical to that in the
various original pinmux.c, but had some consistency and cleanup fixes
applied during migration.
I removed the definition of struct pmux_tri_ctlr, since this is different
between SoCs (especially Tegra20 vs all others), and it's much simpler to
deal with this via the new REG/MUX_REG/... defines. spl.c, warmboot.c,
and warmboot_avp.c needed updates due to this, since they previously
hijacked this struct to encode the location of some non-pinmux registers.
Now, that code simply calculates these register addresses directly using
simple and obvious math. I like this method better irrespective of the
pinmux code cleanup anyway.

Pad config registers exist in APB_MISC_GP space, and control slew
rate, drive strengh, schmidt, high-speed, and low-power modes for
all of the pingroups in Tegra30. This builds off of the pinmux
way of constructing init tables to configure select pads (SDIOCFG,
for instance) during pinmux_init().
Currently, only SDIO1CFG is changed as per the TRM to work with
the SD-card slot on Cardhu.
