module_register: cannot register simplebus/pcib from kernel; already loaded from kernel
r357614 added CTLFLAG_NEEDGIANT to make it easier to find nodes that are
still not MPSAFE (or already are but aren’t properly marked).
Use it in preparation for a general review of all nodes.
This is non-functional change that adds annotations to SYSCTL_NODE and
SYSCTL_PROC nodes using one of the soon-to-be-required flags.
Mark all obvious cases as MPSAFE. All entries that haven't been marked
as MPSAFE before are by default marked as NEEDGIANT

Delay the attachment of children, when requested, until after interrutps are
running. This is often needed to allow children to run transactions on i2c or
spi busses. It's a common enough idiom that it will be useful to have its own
wrapper.

Interrupt based driver, implements SPI mode and clock configuration.
Tested on espressobin and SG-3200.

This controller is a bit tricky as the STOP condition must be indicated in
the last tranferred byte, some devices will not like the repeated start
behavior of this controller. A proper fix to this issue is in the works.
This driver works in polling mode, can be used early in the boot (required
in some cases).

in simple multifunction driver.
- follow interrupt changes in DT. Split old ICU driver to function oriented
parts and add drivers for newly defined parts (system error interrupts).
- Many drivers are children of simple multifunction driver. But after r349596
simple MF driver doesn't longer exports memory resources, and all children
must use syscon interface to access their registers. Adapt affected
drivers to this fact.

The fdt node for this driver is a simple-mfd and syscon compatible one
meaning that simplemfd will be the driver attached for it. The gpio driver
is attached to the 'gpio' subnode so use syscon_get_handle_default to
obtain the handle of the syscon from the parent device and use this
to read/write to the memory region.
MFC after: 1 week
Since r349596 the syscon driver will map the memory. Since the gpio/pinctrl
controller wants it too set it to SHAREABLE.
This fix the gpio controller for attaching and so consumer can use it.
Now the sdhci_xenon driver can detect presence of an sdcard and attach
the mmc driver.

Nothing uses these anymore. They were for super small armv4 boards without
uboot. We removed armv4 support before 13.0, but neglected to garbage collect
this at the same time. Today, both flavors of armv5 kernels (mv and ralink) boot
via uboot which has its own compression scheme for boards that need it.
Note: OLDFILES has not been updated beacuse installkernel will move the whole
directory out of the way before installing the new kernel.

NANDFS has been broken for years. Remove it. The NAND drivers that
remain are for ancient parts that are no longer relevant. They are
polled, have terrible performance and just for ancient arm
hardware. NAND parts have evolved significantly from this early work
and little to none of it would be relevant should someone need to
update to support raw nand. This code has been off by default for
years and has violated the vnode protocol leading to panics since it
was committed.

The A3700 has a different GPIO controller and thus, do not use the old (and

The pinctrl driver, also part of the controller, is not supported yet (but

This allows replacing "sys/eventfilter.h" includes with "sys/_eventfilter.h"
in other header files (e.g., sys/{bus,conf,cpu}.h) and reduces header
pollution substantially.
EVENTHANDLER_DECLARE and EVENTHANDLER_LIST_DECLAREs were moved out of .c
files into appropriate headers (e.g., sys/proc.h, powernv/opal.h).
As a side effect of reduced header pollution, many .c files and headers no
longer contain needed definitions. The remainder of the patch addresses
adding appropriate includes to fix those files.
LOCK_DEBUG and LOCK_FILE_LINE_ARG are moved to sys/_lock.h, as required by
sys/mutex.h since r326106 (but silently protected by header pollution prior
to this change).
No functional change (intended). Of course, any out of tree modules that
relied on header pollution for sys/eventhandler.h, sys/lock.h, or
sys/mutex.h inclusion need to be fixed. __FreeBSD_version has been bumped.
Add parentheses to perform assignment before comparison. The prior
condition worked because fdt_parent_addr_cells returns 1 for the DTB
on which fdt_fixup_ranges is called and accidentally par_addr_cells
ends up to be set to the same value.

mv_pci driver reads PCI memory window layout from DTB data and if the
data is incomplete falls back to default value. The value is too small
to fit two PCI spaces for mwlwifi devices on WRT3200ACM so the resource
allocation for them fails. Increase the default to 4Mb from 1Mb so

OF_getprop_alloc takes element size argument and returns number of
elements in the property. There are valid use cases for such behavior
but mostly API consumers pass 1 as element size to get string
properties. What API users would expect from OF_getprop_alloc is to be
a combination of malloc + OF_getprop with the same semantic of return
value. This patch modifies API signature to match these expectations.
For the valid use cases with element size != 1 and to reduce
modification scope new OF_getprop_alloc_multi function has been
introduced that behaves the same way OF_getprop_alloc behaved prior to
this patch.
