- Atomics-related code sees some rework & cleanup, most notably allowing
Loongson LL/SC errata workarounds to be more bulletproof & their
correctness to be checked at build time.
- Command line setup code is simplified somewhat, resolving various
corner cases.
- MIPS kernels can now be built with kcov code coverage support.
- We can now build with CONFIG_FORTIFY_SOURCE=y.
- Miscellaneous cleanups.
And some platform specific changes:
- We now disable some broken TLB functionality on certain Ingenic
systems, and JZ4780 systems gain some devicetree nodes to support
more devices.
- Loongson support sees a number of cleanups, and we gain initial

- We gain support for MediaTek MT7688-based GARDENA Smart Gateway

- SGI IP27 (Origin 2*) see a number of fixes, cleanups &

The firmware corresponding to a device (dev.fwnode) might be able to
provide functional dependency information between a device and its
supplier and consumer devices. Tracking this functional dependency
allows optimizing device probe order and informing a supplier when all
its consumers have probed (and thereby actively managing their
resources).
The existing device links feature allows tracking and using
supplier-consumer relationships. So, this patch adds the add_links()
fwnode callback to allow firmware to create device links for each
device as the device is added.
However, when consumer devices are added, they might not have a supplier
device to link to despite needing mandatory resources/functionality from
one or more suppliers. A waiting_for_suppliers list is created to track
such consumers and retry linking them when new devices get added.

Here is the big driver core update for 5.4-rc1.
There was a bit of a churn in here, with a number of core and OF
platform patches being added to the tree, and then after much discussion
and review and a day-long in-person meeting, they were decided to be
reverted and a new set of patches is currently being reviewed on the
mailing list.
Other than that churn, there are two "persistent" branches in here that
other trees will be pulling in as well during the merge window. One
branch to add support for drivers to have the driver core automatically
add sysfs attribute files when a driver is bound to a device so that the
driver doesn't have to manually do it (and then clean it up, as it
always gets it wrong).
There's another branch in here for generic lookup helpers for the driver
core that lots of busses are starting to use. That's the majority of
the non-driver-core changes in this patch series.
There's also some on-going debugfs file creation cleanup that has been
slowly happening over the past few releases, with the goal to hopefully
get that done sometime next year.
All of these have been in linux-next for a while now with no reported
issues.

shared it.
Also note that that common branch introduced an i2c bug due to a bad

RST conversion is happily mostly behind us.
- A new document on reproducible builds.
- We finally got around to zapping the documentation for hardware support
that was removed in 2004; one doesn't want to rush these things.
- The usual assortment of fixes, typo corrections, etc.
You'll still find a handful of annoying conflicts against other trees,
mostly tied to the last RST conversions; resolutions are straightforward
and the linux-next ones are good.

Hierarchical IRQ domains can be used to stack different IRQ
controllers on top of each other.
Bring hierarchical IRQ domains into the GPIOLIB core with the
following basic idea:
Drivers that need their interrupts handled hierarchically
specify a callback to translate the child hardware IRQ and
IRQ type for each GPIO offset to a parent hardware IRQ and
parent hardware IRQ type.
Users have to pass the callback, fwnode, and parent irqdomain
before calling gpiochip_irqchip_add().
We use the new method of just filling in the struct
gpio_irq_chip before adding the gpiochip for all hierarchical
irqchips of this type.
The code path for device tree is pretty straight-forward,
while the code path for old boardfiles or anything else will
be more convoluted requireing upfront allocation of the
interrupts when adding the chip.
One specific use-case where this can be useful is if a power
management controller has top-level controls for wakeup
interrupts. In such cases, the power management controller can
be a parent to other interrupt controllers and program
additional registers when an IRQ has its wake capability
enabled or disabled.
The hierarchical irqchip helper code will only be available
when IRQ_DOMAIN_HIERARCHY is selected to GPIO chips using
this should select or depend on that symbol. When using
hierarchical IRQs, the parent interrupt controller must
also be hierarchical all the way up to the top interrupt
controller wireing directly into the CPU, so on systems
that do not have this we can get rid of all the extra
code for supporting hierarchical irqs.
