DT law_trgt_if property defines Local Access Window Target Interface.
Local Access Window Target Interface is used for identifying individual
peripheral and mapping its memory to CPU. Interface id is defined by
hardware itself.
U-Boot uses law_trgt_if DT property in PCIe nodes for configuring

Let GPIO library assign of_node from the parent device.
This allows to move GPIO library and drivers to use fwnode
APIs instead of being stuck with OF-only interfaces.

powerpc's asm/prom.h includes some headers that it doesn't
need itself.
In order to clean powerpc's asm/prom.h up in a further step,
first clean all files that include asm/prom.h
Some files don't need asm/prom.h at all. For those ones,
just remove inclusion of asm/prom.h

RTAS runs in real mode (MSR[DR] and MSR[IR] unset) and in 32bits
big endian mode (MSR[SF,LE] unset).
The change in MSR is done in enter_rtas() in a relatively complex way,
since the MSR value could be hardcoded.
Furthermore, a panic has been reported when hitting the watchdog interrupt

When introduced, IRQFD resampling worked on POWER8 with XICS. However
KVM on POWER9 has never implemented it - the compatibility mode code
("XICS-on-XIVE") misses the kvm_notify_acked_irq() call and the native
XIVE mode does not handle INTx in KVM at all.
This moved the capability support

Many archs have termbits.h as octal numbers. It makes hard for humans
to parse the magnitude of large numbers correctly and to compare with
hex ones of the same define.
Convert octal values to hex.
First step is an automated conversion with:
