654b60a8fd arm: dts: k3-am654-base-board: Add r5 specific u-boot dtsi
So far all the u-boot specific properties for both r5 and a53 are
placed in k3-am654-base-board-u-boot.dtsi. But there are few a53
nodes that should be updated but doesn't belong to r5. So create a
separate r5 specific u-boot dtsi.

2121c7e2d5 arm: dts: k3-am65: Fix mmc nodes
Because of fundamental interface issues in am65x pg1, only the
initial sdhci1 node at 25 MHz was added in the u-boot.dtsi
from which both the base-board.dts and r5-base-board.dts
inherit the node. Move the node out to k3-am65-main.dtsi
where it belongs and add the board specific properties
in base-board.dts and r5-base-board.dts

This ensures dts compatibility with the kernel dts in the
base-board.dts and enables the SD card interface at 50 MHz
and High Speed mode

While we are here, also fix the main_mmc0_pins_default
property to be included and inherit from the base-board.dts
instead of the u-boot.dtsi

57a088a0f0 arm: dts: k3-am654-r5-base-board: Fix power-domains for wkup_vtm0
wkup_vtm populates only 1 power-domain cell in it's node. But the
power-domain cell are defined as 2. Due to this the following warning
comes during build:

arch/arm/dts/k3-am654-r5-base-board.dtb: Warning (power_domains_property):

wkup_vtm@42050000:power-domains: property size (8) too small for cell size 2

Fix this by updating the power-domain cells.

Although we currently use the MAIN_UART0 for R5 SPL console output there
are cases where we require access to the MCU_UART0 as well for example in
case of UART-based Y-Modem boot. To support these scenarios add related
DTS definitions to be able to use that UART early on.

To enable the use of an EEPROM-based board detection scheme we need to
be able to access the I2C bus associated with the EEPROMs across all
3 stages of U-Boot: R5 SPL, A53 SPL, and A53 U-Boot (proper). So go
ahead and add/update the wkup_i2c0 peripheral module DTS definitions
and its associated pinmux node accordingly.

7202af927b arm: dts: k3-am654: Sync IOPAD macros with Linux
Transition to the IOPAD macros as used in Linux in which the pin mux
mode is specified using a dedicated parameter while also dropping the
related MUX_MODEx macros that are no longer needed. This transition
will allow us to keep both Linux and U-Boot DTS in sync more easily.
While at it also align the file name of the include file itself and
update any references accordingly.

12df71cd74 armv7R: dts: k3: am654: Switch DMSC TX message thread ID
Switch from using the high priority DMSC transmit message queue used
by the secure R5 MCU island boot context to the low priority message
queue. While the change in priority is irrelevant for the current boot
architecture it however gives us access to a deeper message queue that
will allow us to buffer more messages. This is an important aspect when
sending several messages without requesting and waiting for a response
in a row which is a communication scheme used during core shutdown for
example. See AM654 TISCI User Guide for additional details.
