d56fe359e6 ARM: dts: am57xx-idk: switch to new cpsw switch drv
Switch all am571/2/4-idk boards to use new cpsw switch driver.
Those boards have 2 Ext. port wired and configured in dual_mac mode by
default. Hence, dual_mac mode has been preserved the same way between
legacy and new driver it's safe to switch drivers.

75f66813e0 Replace HTTP links with HTTPS ones: OMAP DEVICE TREE SUPPORT
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.

b0bbc039d0 ARM: dts: am574x-idk: Disable m_can node
Since commit bcbb63b80284 ("ARM: dts: dra7: Separate AM57 dtsi files"),
the m_can node was inherited from dra76x.dtsi but the IP is not
connected on the idk board. Disable the node to reflect this.

Add DT nodes for new cpsw switchdev driver for am571x-idk board for now to
enable testing of the new solution.

fb59ee37cf ARM: dts: am57xx: Disable voltage switching for SD card
If UHS speed modes are enabled, a compatible SD card switches down to
1.8V during enumeration. If after this a software reboot/crash takes
place and on-chip ROM tries to enumerate the SD card, the difference in
IO voltages (host @ 3.3V and card @ 1.8V) may end up damaging the card.

The fix for this is to have support for power cycling the card in
hardware (with a PORz/soft-reset line causing a power cycle of the
card). Because the beaglebone X15 (rev A,B and C), am57xx-idks and
am57xx-evms don't have this capability, disable voltage switching for
these boards.

The major effect of this is that the maximum supported speed
mode is now high speed(50 MHz) down from SDR104(200 MHz).

commit 88a748419b84 ("ARM: dts: am57xx-idk: Remove support for voltage
switching for SD card") did this only for idk boards. Do it for all
affected boards.

bcbb63b802 ARM: dts: dra7: Separate AM57 dtsi files
AM5 and DRA7 SoC families have different set of modules
in them so the SoC sepecific dtsi files need to be separated.

e.g. Some of the major differences between AM576 and DRA76

		DRA76x	AM576x

USB3		x
USB4		x
ATL		x
VCP		x
MLB		x
ISS		x
PRU-ICSS1		x
PRU-ICSS2		x

This patch only deals with disabling USB3, USB4 and ATL for
AM57 variants.

fc7a0397d2 ARM: dts: am57xx-beagle-x15/am57xx-idk: Fix pinctrl-names
The IO lines of MMC2 in am57xx-beagle-x15/am57xx-idk is connected to
3.3v. Use "ddr_3_3v" instead of "ddr_1_8v" to indicate DDR mode
works in 3.3v on these boards.

configuration values for the various MMC modes for am574x SoC
and use it in the pinctrl properties of MMC devicetree

704f423ce0 ARM: dts: am57xx: Add support for am574x-idk
am574x-idk is similar to am572x-idk with am574x SoC. So create
a common file for both evms and include SoC dtsi as needed.
