ae781d56fe arm: dts: exynos: Add ramp delay property to LDO regulators to Odroid XU3 family
Add startup time to LDO regulators of S2MPS11 PMIC on Odroid XU3/XU4/HC1
family of boards to be sure the voltage is proper before relying on the
regulator.

The datasheet for all the S2MPS1x family is inconsistent here and does
not specify unambiguously the value of ramp delay for LDO.  It mentions
30 mV/us in one timing diagram but then omits it completely in LDO
regulator characteristics table (it is specified for bucks).

However the vendor kernels for Galaxy S5 and Odroid XU3 use values of 12
mV/us or 24 mV/us.

Without the ramp delay value the consumers do not wait for voltage
settle after changing it.  Although the proper value of ramp delay for
LDOs is unknown, it seems safer to use at least some value from
reference kernel than to leave it unset.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
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.

568197fa03 ARM: dts: exynos: fix property values of LDO15/17 for ODROID-XU3/4
Looking at the schematic, LDO15 and LDO17 are tied as a power source of a
builtin network chipset. The voltage on LDO15 is corrected to 3.3V and the
name of LDO17 is corrected to "vdd_ldo17".

9090d1dd0e Odroid-XU3: dts: enable ADC, with request for pre-reloc bind
This ADC is required for Odroid's board revision detection.
The pre-reloc request is enabled, since board detection will
be done in one of early function call.
