fa09b12dc5 arm: ti: k3: Resync dts files and bindings with Linux Kernel v5.14
This resyncs the dts files for all of the currently in-tree K3
platforms, along with relevant bindings, with the v5.14 Linux Kernel
release.  Of note are that the main-navss/mcu-navss nodes were renamed
to main_navss / mcu_navss and so the u-boot.dtsi files needed to be
updated to match.

Tested on j721e_evm and am65x_evm.

9aa4302c02 arm: dts: k3-am654-base-board: Limit Sd card to High speed modes
There's an issue with the base board in which the power cycle
circuit takes way longer to power down than expected by mmc core.
code. This prevents the card from enumerating in UHS modes.

Disable UHS modes for this board until a new board revision fixes
the issue.

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

d5a1f4f551 arm: dts: k3-am654: Increase OSPI default frequency to 50MHz
In 1 bit mode OSPI can work at upto 50MHz, this provides better write
performance. Therefore increase frequency from 40MHz to 50MHz

35f21c3ac6 arm: dts: k3-am65-mcu: Add MCU domain R5F DT nodes
The AM65x SoCs has a single dual-core Arm Cortex-R5F processor
subsystem/cluster (MCU_R5FSS0) within the MCU domain. This cluster
can be configured at boot time to be either run in a LockStep mode
or in an Asymmetric Multi Processing (AMP) fashion in Split-mode.
This subsystem has 64 KB each Tightly-Coupled Memory (TCM) internal
memories for each core split between two banks - ATCM and BTCM
(further interleaved into two banks). There are some IP integration
differences from standard Arm R5 clusters such as the absence of
an ACP port, presence of an additional TI-specific Region Address
Translater (RAT) module for translating 32-bit CPU addresses into
larger system bus addresses etc.

Add the DT node for the MCU domain R5F cluster/subsystem, the two
R5 cores are added as child nodes to the main cluster/subsystem node.
The cluster is configured to run in Split-mode by default, with the
ATCMs enabled to allow the R5 cores to execute code from DDR with
boot-strapping code from ATCM. The inter-processor communication
between the main A72 cores and these processors is achieved through
shared memory and Mailboxes.

ba7907c79c arm64: dts: k3-am654-base-board: Add I2C GPIO expander @ 0x38
The AM654 base board has a TCA9554/PCA9554-type GPIO expander on the
wkup_i2c0 bus at address 0x38 that is used to detect the presence of
daughter cards.  Add a respective DTS description of this expander
to enable its use.

7e0363b285 arm: dts: k3-am654-base-board: Enable wkup_i2c0 across all boot stages
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.

3a1a0dfc39 arm64: dts: k3: Sync sdhci0 node from kernel and change driver name
Sync the sdhci0 node from kernel. This changes the compatible that is
required to be there in the driver. Change the same for the SD card node
which is not yet supported in kernel. This also syncs the main_pmx0 node
as a side effect.

Also change the name of the driver to match the compatible in kernel.
