It turns out that the current PCIe reset implementation in the PCIe
board init function is not quite working reliably due to PCIe reset
timing violations. Fix this by overriding the
tegra_pcie_board_port_reset() function.
Also allow optionally bringing up the PCIe switch as found on the Apalis
Evaluation board. Note however that the Apalis PCIe port is also left
disabled in the device tree by default.

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.

Convert this PMIC driver to driver model and fix up other users. The
regulator and GPIO functions are now handled by separate drivers.
Update nyan-big to work correct. Three boards will need to be updated by
the maintainers: apalis-tk1, cei-tk1-som. Also the TODO in the code re
as3722_sd_set_voltage() needs to be completed.

This patch adds board support for the Toradex Apalis TK1 a computer on
module which can be used on different carrier boards.
The module consists of a Tegra TK1 SoC, a PMIC solution, 2 GB of DDR3L
RAM, a bunch of level shifters, an eMMC, a TMP451 temperature sensor
chip, an I210 gigabit Ethernet controller and a SGTL5000 audio codec.
Furthermore, there is a Kinetis MK20DN512 companion micro controller for
analogue, CAN and resistive touch functionality.
For the sake of ease of use we do not distinguish between different
carrier boards for now as the base module features are deemed
sufficient enough for regular booting.
The following functionality is working so far:
- eMMC boot, environment storage and Toradex factory config block
- Gigabit Ethernet
- MMC/SD cards (both MMC1 as well as SD1 slot)
- USB client/host (dual role OTG port as client e.g. for DFU/UMS or host,
other two ports as host)
