5f3cc16483 ARM: dts: am57xx-idk: Enable dual role for USB2 port
Dual-role support was added in v4.12. We should be using
it for USB2 port on the am57xx-idk.

edfc459c10 ARM: dts: am57xx-idk: Use pinctrl group from dra7-mmc-iodelay.dtsi to select pulldown
commit 18aa0f4bca ("ARM: dts: am57xx-idk: Select pull down
for mmc1_clk line in default mode") modified mmc1_pins_default
pinctrl group in am57xx-idk-common.dtsi in order to change the CLK
line to PIN_INPUT_PULLDOWN. However instead of modifying the pinctrl
group, use the new pinctrl group "mmc1_pins_default_no_clk_pu" in
dra7-mmc-iodelay.dtsi added specifically to be used for CLK line without
external pull up.

18aa0f4bca ARM: dts: am57xx-idk: Select pull down for mmc1_clk line in default mode
During a short period when the bus voltage is switched from 3.3v to 1.8v,
(to enumerate UHS mode), the mmc module is disabled and the mmc IO lines
are kept in a state according to the programmed pad mux pull type.

According to 4.2.4.2 Timing to Switch Signal Voltage in "SD Specifications
Part 1 Physical Layer Specification Version 5.00 February 22, 2016", the
host should hold CLK low for at least 5ms.

In order to keep the card line low during voltage switch, the pad mux of
mmc1_clk line should be configured to pull down.

This is specific to am57xx-idk (and not all dra72/dra74 based boards)
since mmc1_clk line in am57xx-idk is not connected to an external
pullup.

While at that change the order of header files in am571x-idk.dts and
am572x-idk.dts so that the modified pinctrl values in am57xx-idk-common
could take effect.

AM572x IDK and AM571x IDK boards have equivalent
design of how SD card and eMMC are connected.

The two EVMs mainly differ in IOdelay configuration
needed (because of difference in SoC used).

Move the common properties to am57xx-idk-common.dtsi
file which is common for both EVMs.

85d604902e ARM: Device-tree updates
Device-tree continues to see lots of updates. The majority of patches
 here are smaller changes for new hardware on existing platforms, and
 there are a few larger changes worth pointing out.
 
 Major new platforms:
 
  - Gemini has been ported to DT, so a handful of "new" platforms moved over
    from board files
  - Rockchip RK3288 support for Tinkerboard and Phytec phyCORE-RK3288 SoM and RDK
  - A bunch of embedded platforms, several Linksys platforms, Synology DS116,
  - Motorola Droid4 (really old OMAP-based phone) support is added.
 
 Some refactorings, i.e. Allwinner H3/H5 support is commonalized.
 
 And lots of smaller changes, cleanups, etc. See shortlog for more description
 
 We're adding ability to cross-include DT files between arm and arm64,
 by creating appropriate links in the dt-include directory, and using arm/
 and arm64/ as include prefixes. This will avoid other local hacks such as
 per-file links between the two arch trees (this broke for external mirroring
 of DT contents). Now they can just provide their own appropriate dt-include
 hierarcy per platform.

The AM572x-IDK board is a board based on TI's AM5728 SOC
which has a dual core 1.5GHz A15 processor. This board is a
development platform for the Industrial market with:
- 2GB of DDR3L
- Dual 1Gbps Ethernet
- HDMI,
- PRU-ICSS
- uSD
- 16GB eMMC
- CAN
- RS-485
- PCIe
- USB3.0
- Video Input Port
- Industrial IO port and expansion connector

The link to the data sheet and TRM can be found here:

http://www.ti.com/product/AM5728

This patch creates a common dtsi file that will provide a common board
dtsi file to define the nodes that are common to AM57xx (including the
upcoming AM5718) IDK boards.

Initial support is only for basic peripherals
