[ Upstream commit 3b6345e3fcf4c93a79f396121cd0e6f98f04da13 ]

SDHCI nodes defined in the top-level AM64 SoC dtsi files are incomplete
and will not be functional unless they are extended.

As the attached SD/eMMC is only known about at the board integration level,
these nodes should only be enabled when provided with this information.

Disable the SDHCI nodes in the dtsi files and only enable the ones that
are actually pinned out on a given board.

Pull ARM devicetree updates from Arnd Bergmann:
"These are the devicetree updates for Arm and RISC-V based SoCs, mainly
from Qualcomm, NXP/Freescale, Aspeed, TI, Rockchips, Samsung, ST and
Starfive.

Only a few new SoC got added:

- TI AM62P5, a variant of the existing Sitara AM62x family

- Intel Agilex5, an FPGFA platform that includes an Cortex-A76/A55
SoC.

- Qualcomm ipq5018 is used in wireless access points

- Qualcomm SM4450 (Snapdragon 4 Gen 2) is a new low-end mobile phone
platform.

In total, 29 machines get added, which is low because of the summer
break. These cover SoCs from Aspeed, Broadcom, NXP, Samsung, ST,
Allwinner, Amlogic, Intel, Qualcomm, Rockchip, TI and T-Head. Most of
these are development and reference boards.

Despite not adding a lot of new machines, there are over 700 patches
in total, most of which are cleanups and minor fixes"

Merge tag 'soc-dt-6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull ARM SoC devicetree updates from Arnd Bergmann:
"The biggest change this time is for the 32-bit devicetree files, which
are all moved to a new location, using separate subdirectories for
each SoC vendor, following the same scheme that is used on arm64, mips
and riscv. This has been discussed for many years, but so far we never
did this as there was a plan to move the files out of the kernel
entirely, which has never happened.

The impact of this will be that all external patches no longer apply,
and anything depending on the location of the dtb files in the build
directory will have to change. The installed files after 'make
dtbs_install' keep the current location.

There are six added SoCs here that are largely variants of previously
added chips. Two other chips are added in a separate branch along with
their device drivers.

- The Samsung Exynos 4212 makes its return after the Samsung Galaxy
Express phone is addded at last. The SoC support was originally
added in 2012 but removed again in 2017 as it was unused at the
time.

- Amlogic C3 is a Cortex-A35 based smart IP camera chip

- Qualcomm MSM8939 (Snapdragon 615) is a more featureful variant of
the still common MSM8916 (Snapdragon 410) phone chip that has been
supported for a long time.

- Qualcomm SC8180x (Snapdragon 8cx) is one of their earlier high-end
laptop chips, used in the Lenovo Flex 5G, which is added along with
the reference board.

- Qualcomm SDX75 is the latest generation modem chip that is used as
a peripherial in phones but can also run a standalone Linux. Unlike
the prior 32-bit SDX65 and SDX55, this now has a 64-bit Cortex-A55.

- Alibaba T-Head TH1520 is a quad-core RISC-V chip based on the
Xuantie C910 core, a step up from all previously added rv64 chips.

All of the above come with reference board implementations, those
included there are 39 new board files, but only five more 32-bit this
time, probably a new low:

- Marantec Maveo board based on dhcor imx6ull module

- Endian 4i Edge 200, based on the armv5 Marvell Kirkwood chip

- Epson Moverio BT-200 AR glasses based on TI OMAP4

- PHYTEC STM32MP1-3 Dev board based on STM32MP15 PHYTEC SOM

- ICnova ADB4006 board based on Allwinner A20

On the 64-bit side, there are also fewer addded machines than we had
in the recent releases:

- Three boards based on NXP i.MX8: Emtop SoM & Baseboard, NXP i.MX8MM
EVKB board and i.MX8MP based Gateworks Venice gw7905-2x device.

- NVIDIA IGX Orin and Jetson Orin Nano boards, both based on tegra234

- Qualcomm gains support for 6 reference boards on various members of
their IPQ networking SoC series, as well as the Sony Xperia M4 Aqua
phone, the Acer Aspire 1 laptop, and the Fxtec Pro1X board on top
of the various reference platforms for their new chips.

- Rockchips support for several newer boards: Indiedroid Nova
(rk3588), Edgeble Neural Compute Module 6B (rk3588), FriendlyARM
NanoPi R2C Plus (rk3328), Anbernic RG353PS (rk3566), Lunzn
Fastrhino R66S/R68S (rk3568)

- TI K3/AM625 based PHYTEC phyBOARD-Lyra-AM625 board and Toradex
Verdin family with AM62 COM, carrier and dev boards

Other changes to existing boards contain the usual minor improvements
along with

- continued updates to clean up dts files based on dtc warnings and
binding checks, in particular cache properties and node names

- support for devicetree overlays on at91, bcm283x

- significant additions to existing SoC support on mediatek,
qualcomm, ti k3 family, starfive jh71xx, NXP i.MX6 and i.MX8, ST
STM32MP1

As usual, a lot more detail is available in the individual merge

arm64: dts: ti: k3-am64: Only set UART baud for used ports

As the binding for "current-speed" states, this should only be used
when the baud rate of an attached device cannot be detected. This is
the case for our attached on-board USB-to-UART converter used for
early kernel console. For all other unconnected/disabled ports this
can be configured in userspace later, DT is not the place for device
configuration, especially when there are already standard ways to
set serial baud in userspace.

Remove setting baud for all disabled serial ports and move setting
it for the couple enabled ports down into the board files.

arm64: dts: ti: k3-am64: Enable Mailbox nodes at the board level

Mailbox nodes defined in the top-level AM64x SoC dtsi files are incomplete
and may not be functional unless they are extended with a chosen interrupt
and connection to a remote processor.

As the remote processors depend on memory nodes which are only known at
the board integration level, these nodes should only be enabled when
provided with the above information.

Disable the Mailbox nodes in the dtsi files and only enable the ones that
are actually used on a given board.

arm64: dts: ti: k3-am64: Add general purpose timers

There are 11 general purpose timers on am64 that can be used for things
like PWM using pwm-omap-dmtimer driver. There are also additional four
timers in the MCU domain that do not have interrupts routable for Linux.

We configure the timers with the 25 MHz input clock by default as the
32.768 kHz clock may not be wired on the device. We leave the MCU domain
timers clock mux unconfigured, and mark the MCU domain timers reserved.
The MCU domain timers are likely reserved by the software for the ESM
module.

Compared to am65, the timers on am64 do not have a dedicated IO mux for
the timers. On am62, the timers have different interrupts, clocks and
power domains compared to am65, and the MCU timers are at a different
IO address. Compared to AM62, the AM64 times have different clocks and
count in main domain are different as well.
