There is a timer wrap issue on dra7 for the ARM architected timer.
In a typical clock configuration the timer fails to wrap after 388 days.
To work around the issue, we need to use timer-ti-dm percpu timers instead.
Let's configure dmtimer3 and 4 as percpu timers by default, and warn about
the issue if the dtb is not configured properly.
Let's do this as a single patch so it can be backported to v5.8 and later
kernels easily. Note that this patch depends on earlier timer-ti-dm
systimer posted mode fixes, and a preparatory clockevent patch
"clocksource/drivers/timer-ti-dm: Prepare to handle dra7 timer wrap issue".
For more information, please see the errata for "AM572x Sitara Processors
Silicon Revisions 1.1, 2.0":
https://www.ti.com/lit/er/sprz429m/sprz429m.pdf
The concept is based on earlier reference patches done by Tero Kristo and
Keerthy.

This is a relatively low-cost AST2500-based Xeon E-2100/E-2200 series
mini-ITX board that we hope can provide a decent platform for OpenBMC
development.
This initial device-tree provides the necessary configuration for
basic BMC functionality such as host power control, serial console and
KVM support, and POST code snooping.

Samsung DTS ARM changes for v5.13
1. Configure battery charger and front camera on GT-I9100 phone.
2. Fix in several boards the Maxim PMIC/MUIC/fuel gauge interrupt flags
to match real type of interrupt coming from the device.
3. Correct DTS with dtschema. This brings back the commit adding input
clock to CMU in Exynos4412 Odroid which was reverted some time ago
due to unsupported deferred probes (now supported and tested).

Missing "chosen" node can cause issues when booting a kernel
with a boot-loader that doesn't create a chosen node if this
isn't present in the DTB since the decompressor relies on a
pre-existing chosen node to be available to insert the command
line and merge other ATAGS info.

Use the `marvell,reg-init` DT property to configure the LED[2]/INTn pin
of the Marvell 88E1514 ethernet PHY on Turris Omnia into interrupt mode.
Without this the pin is by default in LED[2] mode, and the Marvell PHY
driver configures LED[2] into "On - Link, Blink - Activity" mode.
This fixes the issue where the pca9538 GPIO/interrupt controller (which
can't mask interrupts in HW) received too many interrupts and after a
time started ignoring the interrupt with error message:
IRQ 71: nobody cared
There is a work in progress to have the Marvell PHY driver support
parsing PHY LED nodes from OF and registering the LEDs as Linux LED
class devices. Once this is done the PHY driver can also automatically
set the pin into INTn mode if it does not find LED[2] in OF.
Until then, though, we fix this via `marvell,reg-init` DT property.
