[ Upstream commit 3a47e381670f130870caef6e1155ac531b17b032 ]

The clock IDs for multiple MCSPI instances across wakeup as
well as main domain in J7200 are incorrect when compared with
documentation [1]. This results in kernel crashes when the said
instances are enabled. Fix the clock ids to their appropriate
values.

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-j7200: Configure pinctrl for timer IO pads

There are timer IO pads in the MCU domain, and in the MAIN domain. These
pads can be muxed for the related timers.

There are timer IO control registers for input and output. The registers
for CTRLMMR_TIMER*_CTRL and CTRLMMR_MCU_TIMER*_CTRL are used to control
the input. The registers for CTCTRLMMR_TIMERIO*_CTRL and
CTRLMMR_MCU_TIMERIO*_CTRL the output.

The multiplexing is documented in TRM "5.1.2.3.1.4 Timer IO Muxing Control
Registers" and "5.1.3.3.1.5 Timer IO Muxing Control Registers", and the
CASCADE_EN bit is documented in TRM "12.6.3.1 Timers Overview".

For chaining timers, the timer IO control registers also have a CASCADE_EN
input bit in the CTRLMMR_TIMER*_CTRL in the registers. The CASCADE_EN bit
muxes the previous timer output, or possibly and external TIMER_IO pad
source, to the input clock of the selected timer instance for odd numered
timers. For the even numbered timers, the CASCADE_EN bit does not do
anything. The timer cascade input routing options are shown in TRM
"Figure 12-3224. Timers Overview". For handling beyond multiplexing, the
driver support for timer cascading should be likely be handled via the
clock framework.

The MCU timer controls are also marked as reserved for
usage by the MCU firmware.

arm64: dts: ti: k3-j7200: Add general purpose timers

There are 20 general purpose timers on j721e that can be used for
things like PWM using pwm-omap-dmtimer driver. There are also
additional ten timers in the MCU domain which are meant for MCU
firmware usage and hence marked reserved by default.

The odd numbered timers have the option of being cascaded to even
timers to create a 64 bit non-atomic counter which is racy in simple
usage, hence the clock muxes are explicitly setup to individual 32 bit
counters driven off system crystal (HFOSC) as default.

arm64: dts: ti: k3-j7200-mcu: Add mcu_secproxy

MCU domain has it's own secure proxy for communicating with ROM and
for R5 micro controller firmware operations. This is in addition to
the one in the main domain NAVSS subsystem that is used for general
purpose communication.

Describe the node for use with bootloaders and firmware that require
this communication path which uses interrupts to corresponding micro
controller interrupt controller. Mark the node as disabled since this
instance does not have interrupts routed to the main processor by
default for a complete description of the node.
