delay select values for MMCSD subsystems
The following speed modes are now supported in J7200 SoC,
- HS200 and HS400 modes at 1.8 V card voltage, in MMCSD0 subsystem [1].
- UHS-I speed modes in MMCSD1 subsystem [1].
Add support for UHS-I modes by adding voltage regulator device tree nodes
and corresponding pinmux details, to power cycle and voltage switch cards.
Set respective tags in sdhci0 and remove no-1-8-v tag from sdhci1
device tree nodes.
Also update the delay values for various speed modes supported, based on
the revised january 2021 J7200 datasheet[2].

There are 6 gpio instances inside SoC with 2 groups as show below:
Group one: wkup_gpio0, wkup_gpio1
Group two: main_gpio0, main_gpio2, main_gpio4, main_gpio6
Only one instance from each group can be used at a time. So use main_gpio0
and wkup_gpio0 in current linux context and disable the rest of the nodes.

There are 4 instances of gpio modules in main domain:
gpio0, gpio2, gpio4 and gpio6
Groups are created to provide protection between different processor
virtual worlds. Each of these modules I/O pins are muxed within the
group. Exactly one module can be selected to control the corresponding
pin by selecting it in the pad mux configuration registers.
This group in main domain pins out 69 lines (5 banks). Add DT modes for
each module instance in the main domain.
Similar to the gpio groups in main domain, there is one gpio group in
wakeup domain with 2 module instances in it.
The gpio group pins out 72 pins (6 banks) of the first 85 gpio lines. Add
DT nodes for each module instance in the wakeup domain.

Add the sub-mailbox nodes that are used to communicate between MPU and
various remote processors present in the AM64x SoCs for the AM642 EVM
and AM642 SK boards. These include the R5F remote processors in the two
dual-R5F clusters (MAIN_R5FSS0 & MAIN_R5FSS1) in the MAIN domain; and a
M4 processor in the MCU safety island.
These sub-mailbox nodes utilize the System Mailbox clusters 2, 4 and 6.
The remaining clusters 3, 5 and 7 are currently not used, and so are
disabled. Clusters 0 and 1 were never added to the dts file as they do
not support interrupts towards the A53 core.
The sub-mailbox nodes added match the hard-coded mailbox configuration
used within the TI RTOS IPC software packages. The R5F processor
sub-systems are assumed to be running in Split mode, so a sub-mailbox
node is used by each of the R5F cores. Only the sub-mailbox node for
the first R5F core in each cluster is used in case of a Single-CPU mode
for that R5F cluster.
NOTE:
The cluster nodes only have the Mailbox IP interrupt outputs that are
routed to the GIC_SPI. The sub-mailbox nodes' irq-id are indexing into
the listed interrupts, with the usr-id using the actual interrupt output
line number from the Mailbox IP.

The AM64 MAIN domain contains a Mailbox IP instance with multiple
clusters, and is a variant of the IP on current AM65x and J721E
SoCs. The AM64x SoC has only 8 clusters with no interrupts routed
to the A53 core on the first 2 clusters. The interrupt outputs
from the IP do not go through any Interrupt Routers and are
hard-wired to each processor, with only couple of interrupts
from each cluster reaching the A53 core.
Add all the Mailbox clusters that generate interrupts towards the
A53 core as their own nodes under the cbass_main node instead of
creating an almost empty parent node for the Mailbox IP and the
clusters as its child nodes. All these nodes are enabled by default
in the base dtsi file, but any cluster that does not define any
child sub-mailbox nodes should be disabled in the corresponding
board dts files.

Set the Tx bus width to 8 so 8D-8D-8D mode can be selected. Change the
frequency to 25 MHz. This is the frequency that the flash has been
successfully tested with in Octal DTR mode. The total performance should
still increase since 8D-8D-8D mode should be at least twice as fast as
1S-1S-8S mode.

itap delay values for MMCSD subsystems
According to latest errata of J721e [1], HS400 mode is not supported
in MMCSD0 subsystem (i2024) and SDR104 mode is not supported in MMCSD1/2
subsystems (i2090). Therefore, replace mmc-hs400-1_8v with mmc-hs200-1_8v
in MMCSD0 subsystem and add a sdhci mask to disable SDR104 speed mode.
Also, update the itap delay values for all the MMCSD subsystems according
the latest J721e data sheet[2]

Add the DT entry for a watchdog based on RTI1.
On SR1.0 silicon, it requires additional firmware on the MCU R5F cores
to handle the expiry, e.g. https://github.com/siemens/k3-rti-wdt. As
this firmware will also lock the power domain to protect it against
premature shutdown, mark it shared.

Add the DT nodes for the ICSSG0 and ICSSG1 processor subsystems that are
present on the K3 J721E SoCs. The two ICSSGs are identical to each other
for the most part, with the ICSSG1 supporting slightly enhanced features
for supporting SGMII PRU Ethernet. Each ICSSG instance is represented by
a PRUSS subsystem node and other child nodes. These nodes are enabled by
default.
The ICSSGs on K3 J721E SoCs are revised versions of the ICSSG on the first
AM65x SR1.0 SoCs. The PRU IRAMs are slightly smaller, and the IP includes
two new auxiliary PRU cores called Tx_PRUs. The Tx_PRUs have 6 KB of IRAMs
and leverage the same host interrupts as the regular PRU cores. All The
ICSSG host interrupts intended towards the main Arm core are also shared
with other processors on the SoC, and can be partitioned as per system
integration needs.
The ICSSG subsystem node contains the entire address space. The various
sub-modules of the ICSSG are represented as individual child nodes (so
platform devices themselves) of the PRUSS subsystem node. These include
the two PRU cores, two RTU cores, two Tx_PRU cores and the interrupt
controller. All the Data RAMs are represented within a child node of
its own named 'memories' without any compatible. The Real Time Media
Independent Interface controller (MII_RT), the Gigabit capable MII_G_RT
and the CFG sub-module are represented as syscon nodes. The ICSSG CFG
sub-module provides two internal clock muxes, and these are represented
as children of the CFG child node 'clocks' by the 'coreclk-mux' and
iepclk-mux' clk nodes. The default parents for these mux clocks are also
defined using the assigned-clock-parents property.
The DT nodes use all standard properties. The regs property in the
PRU/RTU/Tx_PRU nodes define the addresses for the Instruction RAM, the
Debug and Control sub-modules for that PRU core. The firmware for each
PRU/RTU/Tx_PRU core is defined through a 'firmware-name' property.
The default names for the firmware images for each PRU, RTU and Tx_PRU
cores are defined as follows (these can be adjusted either in derivative
board dts files or through sysfs at runtime if required):
ICSSG0 PRU0 Core : j7-pru0_0-fw ; PRU1 Core : j7-pru0_1-fw
ICSSG0 RTU0 Core : j7-rtu0_0-fw ; RTU1 Core : j7-rtu0_1-fw
ICSSG0 Tx_PRU0 Core : j7-txpru0_0-fw ; Tx_PRU1 Core : j7-txpru0_1-fw
ICSSG1 PRU0 Core : j7-pru1_0-fw ; PRU1 Core : j7-pru1_1-fw
ICSSG1 RTU0 Core : j7-rtu1_0-fw ; RTU1 Core : j7-rtu1_1-fw
ICSSG1 Tx_PRU0 Core : j7-txpru1_0-fw ; Tx_PRU1 Core : j7-txpru1_1-fw
Note:
1. The ICSSG INTC on J721E SoCs share all the host interrupts with other
processors, so use the 'ti,irqs-reserved' property in derivative board
dts files _if_ any of them should not be handled by the host OS.
2. There are few more sub-modules like the Industrial Ethernet Peripherals
(IEPs), MDIO, PWM, UART that do not have bindings and so will be added
in the future.

Add the DT nodes for the ICSSG0, ICSSG1 and ICSSG2 processor subsystems
that are present on the K3 AM65x SoCs. The three ICSSGs are identical
to each other for the most part, with the ICSSG2 supporting slightly
enhanced features for supporting SGMII PRU Ethernet. Each ICSSG instance
is represented by a PRUSS subsystem node. These nodes are enabled by
default.
The ICSSGs on K3 AM65x SoCs are super-sets of the PRUSS on the AM57xx/
6AK2G SoCs except for larger Shared Data RAM and the lack of a PRU-ICSS
crossbar. They include two auxiliary PRU cores called RTUs and few other
additional sub-modules. The interrupt integration is also different on
the K3 AM65x SoCs and are propagated through various SoC-level Interrupt
Router and Interrupt Aggregator blocks. The AM65x SR2.0 SoCs have a
revised ICSSG IP that is based off the subsequent IP used on J721E SoCs,
and has two new auxiliary PRU cores called Tx_PRUs. The Tx_PRUs have 6 KB
of IRAMs and leverage the same host interrupts as the regular PRU cores.
The Broadside (BS) RAM within each core is also sized differently w.r.t
SR1.0.
The ICSSG subsystem node contains the entire address space. The various
sub-modules of the ICSSG are represented as individual child nodes (so
platform devices themselves) of the PRUSS subsystem node. These include
the various PRU cores and the interrupt controller. All the Data RAMs
are represented within a child node of its own named 'memories' without
any compatible. The Real Time Media Independent Interface controllers
(MII_RT and MII_G_RT), and the CFG sub-module are represented as syscon
nodes. The ICSSG CFG module has clock muxes for IEP clock and CORE clock,
these clk nodes are added under the CFG child node 'clocks'. The default
parents for these mux clocks are also assigned.
The DT nodes use all standard properties. The regs property in the
PRU/RTU/Tx_PRU nodes define the addresses for the Instruction RAM, the
Debug and Control sub-modules for that PRU core. The firmware for each
PRU/RTU/Tx_PRU core is defined through a 'firmware-name' property.
The default names for the firmware images for each PRU, RTU and Tx_PRU

ICSSG0 PRU0 Core : am65x-pru0_0-fw ; PRU1 Core : am65x-pru0_1-fw

ICSSG0 Tx_PRU0 Core : am65x-txpru0_0-fw ; Tx_PRU1 Core : am65x-txpru0_1-fw
ICSSG1 PRU0 Core : am65x-pru1_0-fw ; PRU1 Core : am65x-pru1_1-fw
ICSSG1 RTU0 Core : am65x-rtu1_0-fw ; RTU1 Core : am65x-rtu1_1-fw
ICSSG1 Tx_PRU0 Core : am65x-txpru1_0-fw ; Tx_PRU1 Core : am65x-txpru1_1-fw
ICSSG2 PRU0 Core : am65x-pru2_0-fw ; PRU1 Core : am65x-pru2_1-fw
ICSSG2 RTU0 Core : am65x-rtu2_0-fw ; RTU1 Core : am65x-rtu2_1-fw
ICSSG2 Tx_PRU0 Core : am65x-txpru2_0-fw ; Tx_PRU1 Core : am65x-txpru2_1-fw
Note:
1. The ICSSG nodes are all added as per the SR2.0 device. Any sub-module IP
differences need to be handled within the driver using SoC device match
logic or separate dts/overlay files (if needs to be supported) with the
Tx_PRU nodes expected to be disabled at the minimum.
2. The ICSSG INTC on AM65x SoCs share 5, 6, 7 host interrupts with other
processors, so use the 'ti,irqs-reserved' property in derivative board
dts files _if_ any of them should not be handled by the host OS.
3. There are few more sub-modules like the Industrial Ethernet Peripherals
(IEPs), MDIO, PWM, UART that do not have bindings and so will be added
in the future.

On am642-evm the CPSW3g ext. Port1 is directly connected to TI DP83867 PHY
and Port2 is connected to TI DP83869 PHY which is shared with ICSS
subsystem. The TI DP83869 PHY MII interface is configured using pinmux for
CPSW3g, while MDIO bus is connected through GPIO controllable 2:1 TMUX154E
switch (MDIO GPIO MUX) which has to be configured to route MDIO bus from
CPSW3g to TI DP83869 PHY.
Hence add networking support for am642-evm:
- add CPSW3g MDIO and RGMII pinmux entries for both ext. ports;
- add CPSW3g nodes;
- add mdio-mux-multiplexer DT nodes to represent above topology.

Qualcomm ARM64 DT updates for 5.13
This extends the initial SM8350 description merged in v5.12 with
CPUfreq, SMMU, UFS, RPMHPD, SPMI, USB and remoteproc support. It adds
initial PMIC definitions for the 6 PMICs found on the MTP and it
introduces the new SM8350 Hardware Development Kit (HDK).
SC7180 is further polished, the DisplayPort portion of the QMP phy is
defined and several new SKUs of the Trogdor devices are introduced.
The new SC7280 platform is introduced, with RPMH, RPMHPD, RPMCC, SPMI,
CPU idle, SMMU and watchdog defined.
SDM845 gains the camera related nodes and some cleanups.
For SM8250 it brings some cleanups and migrates SPI0 to use GPIO for
chip select.

line is controlled by the QUP itself (see 37dd4b777942 ("arm64: dts:

The PM8150 comes with everything the RTC needs, so let's just leave it
enabled instead of having to explicitly enable it for all boards.
In effect this patch enables the RTC on the SM8150 MTP and the SM8250
HDK.

WSA881x powerdown pin is connected to GPIO1 not gpio2, so correct this.
This was working so far due to a shift bug in gpio driver, however
once that is fixed this will stop working, so fix this!

This moved from being trogdor specific to being part of the general
sc7180.dtsi SoC file in commit 681a607ad21a ("arm64: dts: qcom:
sc7180: Add DisplayPort HPD pin dt node"). Then we dropped the pinconf
from the general sc7180.dtsi file in commit 8d079bf20410 ("arm64: dts:
qcom: sc7180: Drop pinconf on dp_hot_plug_det") and added it back to
the trogdor dts file in commit f772081f4883 ("arm64: dts: qcom:
sc7180: Add "dp_hot_plug_det" pinconf for trogdor").
As part of this we managed to forget to drop the old copy in the
trogdor dts. Let's do it now.
