f7b462646e ARM: dts: exynos: use local header for pinctrl register values
The DTS uses hardware register values directly in pin controller pin
configuration.  These are not some IDs or other abstraction layer but
raw numbers used in the registers.

These numbers were previously put in the bindings header to avoid code
duplication and to provide some context meaning (name), but they do not
fit the purpose of bindings.

Store the constants in a header next to DTS and use them instead of
bindings.

3d992fd8f4 ARM: dts: exynos: fix USB 3.0 VBUS control and over-current pins on Exynos5410
The VBUS control (PWREN) and over-current pins of USB 3.0 DWC3
controllers are on Exynos5410 regular GPIOs.  This is different than for
example on Exynos5422 where these are special ETC pins with proper reset
values (pulls, functions).

Therefore these pins should be configured to enable proper USB 3.0
peripheral and host modes.  This also fixes over-current warning:

    [    6.024658] usb usb4-port1: over-current condition
    [    6.028271] usb usb3-port1: over-current condition

f37b5d3aef ARM: dts: exynos: Replace HTTP links with HTTPS ones
Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

Deterministic algorithm:
For each file:
  If not .svg:
    For each line:
      If doesn't contain `\bxmlns\b`:
        For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
	  If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
            If both the HTTP and HTTPS versions
            return 200 OK and serve the same content:
              Replace HTTP with HTTPS.

17dcc16fbd ARM: dts: exynos: Use macros for pinctrl configuration on exynos5410
Usage of DTS macros instead of hard-coded numbers makes code easier to
read.  One does not have to remember which value means pull-up/down or
specific driver strength.

90c6e35383 ARM: dts: exynos: Use common macros for pinctrl configuration
Replace duplicated macros in each DTSI file with a common macro coming
from header.  Include the header in each pinctrl DTSI so further changes
could use it.

Although PIN_FUNC_SPC_2 does not bring much information about the
function itself, it still is more descriptive then hard-coded
number <2>.
