Sort fixed clocks nodes by clock frequency and memory mapped device
nodes by reg address. Also, sort properties as shown in dt-bindings
examples.

This smartphone uses a MediaTek MT6582 system-on-chip with 512MB of RAM.
It can currently boot into initramfs with a working UART and
Simple Framebuffer using already initialized panel by the bootloader.

Other SoC DTSI files define this property for their uart nodes.
Do the same here too, to be consistent.

Bindings already have mt6582 compatible for timer, so add that to DTSI.
While at it, remove clock-names property (which is not required by timer
node) and fix node address.

At this point, if a symbol is compiled as part of the kernel,
information about which module the symbol belongs to is lost.
To save this it is possible to add the module name to the alias name.
It's not very pretty, but it's possible for now.

Hi all,
This series updates the drv-net XDP program used by the new xdp.py selftest
to use the bpf_dynptr APIs for packet access.
The selftest itself is unchanged.
The original program accessed packet headers directly via
ctx->data/data_end, implicitly assuming headers are always in the linear

I suggest to refine the word wrapping for such a change description.

The "jiggle" code was not actually expecting failure, which it should
because that's what actually happens when the device wasn't already woken
up by the regulator power-on (i.e. in the case of a shared regulator).
Also, do actually enter the internal suspend mode on shutdown,
The TODO about using the number of vCPUs instead of vcpu.id + 1
was already addressed by commit 376bc1b458c9 ("KVM: selftests: Don't
assume vcpu->id is '0' in xAPIC state test"). The comment is now
stale and can be removed.
