It appears that pinctrl-single is misused on this SoC to control both
the mux and the input and output and bias settings. This results in
non-working pinctrl configurations for GPIOs within the device tree.
This is what happens:
(1) During startup the pinctrl settings are applied according to the
device tree. I.e. the pin is configured as output and with
pull-ups enabled.
(2) During startup a device driver requests a GPIO.
(3) pinctrl-single is applying the default GPIO setting according to
the pinctrl-single,gpio-range property.
This would work as expected if the pinctrl-single is only controlling
the function mux, but it also controls the input/output buffer enable,
the pull-up and pull-down settings etc (pinctrl-single,function-mask
covers the entire pad setting instead of just the mux field).
Remove the pinctrl-single,gpio-range property, so that no settings are
applied during a gpio_request() call.

Similar to the TI K3-AM62x Soc commit ce27f7f9e3
("arm64: dts: ti: k3-am62-wakeup: Configure ti-sysc for wkup_uart0")
The devices in the wkup domain are capable of waking up the system from
suspend. We can configure the wkup domain devices in a generic way using
the ti-sysc interconnect target module driver like we have done with the
earlier TI SoCs.
As ti-sysc manages the SYSCONFIG related registers independent of the
child hardware device, the wake-up configuration is also set even if
wkup_uart0 is reserved by sysfw.
The wkup_uart0 device has interconnect target module register mapping like
dra7 wkup uart. There is a 1 MB interconnect target range with one uart IP
block in the target module. The power domain and clock affects the whole
interconnect target module.
Note we change the functional clock name to follow the ti-sysc binding
and use "fck" instead of "fclk".
Also note that we need to disable the target module reset as noted by
Markus. Otherwise the sysfw using wkup_uart0 can get confused on some
devices leading to boot time issues such as mbox timeouts.

gather_bootmem_prealloc() assumes the start nid as 0 and size as
num_node_state(N_MEMORY). That means in case if memory attached numa
nodes are interleaved, then gather_bootmem_prealloc_parallel() will fail
to scan few of these nodes.
Since memory attached numa nodes can be interleaved in any fashion, hence
ensure that the current code checks for all numa node ids
(.size = nr_node_ids). Let's still keep max_threads as N_MEMORY, so that
it can distributes all nr_node_ids among the these many no. threads.

We can run into an infinite loop in __get_longterm_locked() when
collect_longterm_unpinnable_folios() finds only folios that are isolated
from the LRU or were never added to the LRU. This can happen when all
folios to be pinned are never added to the LRU, for example when
vm_ops->fault allocated pages using cma_alloc() and never added them to
the LRU.
Fix it by simply taking a look at the list in the single caller, to see if
anything was added.
