Keerthy 5c8a6b9db5 ARM: dts: am57xx-idk-common: Hook smps12 regulator as cpu vdd-supply
am574x-idk has no cpu vdd-supply at the moment. Hence hook smps12
regulator as cpu vdd-supply in am57xx-idk-common as the same regulator
feeds on to cpu on am571/2/4-idks. So remove all the individual
instances and place that in common place.

Roger Quadros 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.

Kishon Vijay Abraham I 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.

Kishon Vijay Abraham I 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.

Kishon Vijay Abraham I 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.

Sekhar Nori 799ab3f4e0 ARM: dts: am57xx-idk: Move common MMC/SD properties to common file
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.
