9dfa2a5468 arm: dts: Remove some old DTS
RPI is using the firmware provided DTS since 12.0
Pandaboard works with the Linux DTS
RK* Exynos* and Meson*/Odroid* don't even work with current
source code, if someone wants to make them work again they
better use the Linux DTS.

64d41eddd7 Adapt FreeBSD specific DT stub for Jetson TK1 board to be consistent with
update of devicetree to 4.19 in r340337.
Our build system doesn't provide dependencies for included DTS files, so
nobody noticed this issue for long time.

851f1a1121 Fix test-dts{,o} targets
There were two main problems here:

1.) sys/dts/Makefile.inc is not included from various */overlays directories
    by default, only ../Makefile.inc
2.) When shelling out for DTS/DTSO, cwd != .CURDIR, so enumeration always
    failed

These changes allow make test-dts and make test-dtso to function in their
respective directories.

53c6ad1d62 Support RISC-V implementations that do not manage the A and D bits
(e.g. RocketChip, lowRISC and derivatives).

RISC-V page table entries support A (accessed) and D (dirty) bits. The
spec makes hardware support for these bits optional. Implementations that
do not manage these bits in hardware raise page faults for accesses to a
valid page without A set and writes to a writable page without D set.
Check for these types of faults when handling a page fault and fixup the
PTE without calling vm_fault if they occur.

58d5c51106 Remove Atmel AT91RM9200 and AT91SAM9 support.
The last known robust version of this code base was FreeBSD 8.2. There
are no users of this on current, and all users of it have abandoned
this platform or are in legacy mode with a prior version of FreeBSD.

All known users on arm@ approved this removal, and there were no
objections.

95e390b666 Add spi-max-frequency properties to all spigen nodes. This is a required
property for spi devices, although in the spigen case it's expected that
the speed will be overridden at runtime via the ioctl interface.  A very
conservative 500khz speed is used (I've never seen a spi device that
couldn't run at 1mhz).

ce0b0df7ab Add spigen(4) fdt data overlays for RPI-B, RPI-2.
By adding spigen-rpi{2,-b}.dtso to fdt_overlays= in loader.conf, the fdt data
will set up the correct pinmux and device nodes to create a spigen(4) device
for each available chipselect pin.

903da53796 Garbage collect the a83t emac overlays
The 4.16 DTS import brought in emac support for the a83t. Since these
boards' DTS is pulled from /boot and I forgot to hook these up to the build,
they should be fairly safe to go away.

The a83t-sid and h3-sid overlays are still relevant. a83t-sid will likely
come in with 4.18 DTS.

ded9da6832 Update mv_gpio driver to new FreeBSD API
This patch implements and exports functions described
in gpio_if.m file. It also uses new gpiobus_attach_bus function
instead of adding gpioc and gpiobus as children. It removes
ulgy reading SoC ID and related if..else, so it depends only on
data read from FDT.

91cc58af37 [rpi] Add fdt_pinctrl(4) support to Raspberry Pi GPIO driver
On Raspberry Pi platform GPIO controller also responsible for pins
multiplexing. Pi code predates proper FDT support in FreeBSD so a
lot of pinmux info is hardcoded. This patch:

- Implements pinctl methods in bcm2835_gpio
- Converts all devices with ad-hoc pinmux info to proper pin control
  mechanisms and adds pinmux info in FreeBSD's custom dts files.
- Adds fdt_pinctrl option to RPI2 and RPI-B kernels
- Adds SPI pinmux config to FreeBSD's customization of GNU DTS.

1e14d6eb3d Add a83t overlays for sid and emac
The sun8i-a83t-bananapi-m3-emac overlay technically doesn't match what will
be coming from upstream. The tx-delay and rx-delay should be specified in
terms of allwinner,tx-delay-ps and allwinner,rx-delay-ps respectively. The
values are still technically correct for what we write in if_awg, and
support for the new bindings will be coming soon.

Ranges in pcie-controller are unused, so could be changed to match Linux
device tree represntation. Same with interrupt-cells and interrupt-parent.
In PCI controller driver ocd_data are used for matching driver and
choose proper resources acquisition function.
fdt_win_process_child have new argument which provide information
about fdt node containing addresses of MMIO registers.

c7dbc00c34 Match Marvell Armada38X PCI compatible with Linux
In Linux FDT pcie does not have compatible string.
Configuration of windows in mv_common was based on fdt compatible.
Now pcie windows are configured by their parent: pcie_controller.
Processing is moved to fdt_win_process_child. fdt_win_process now
only walk through the tree. SOC_NODE_PCI is position of pcie function in
soc_node_spec array.

PCIe probe cannot use ofw_bus_search_compatible, because it needs to
check also device type and parents compatible.

c2f5940db3 Add dtb overlays support
DTB Overlays are useful to change/add nodes to a dtb without the need to
modify it.
Add support for building dtbo during buildkernel.
The goal of DTBO present in the FreeBSD source tree is to fill a gap in
time when we submit changes upstream (Linux). Instead of waiting 2 to 4 months
we can add a DTBO in tree in the meantime.
This is not for adding DTBO for capes/hat/addon boards, those will be
better to put in a ports.
This is also not for enabling a i2c/spi/pwm controller on certain pins,
each user have a different use case for those (which pins to use etc ...)
and we cannot have all possible configuration.

Add a dtbo for sun8i-h3-sid which add the SID node missing in upstream dts.

8e6a67d5be [rpi] remove IRQ support for BCM233x RNG
Upstream DTBs don't provide IRQ lines for the RNG. Moreover, harvesting
bytes as often as the RNG interrupt is triggered (87 times per sec) is an
overkill.

For these reasons, get rid of the interrupt mode and make callout mode the
default, with random bits harvested every 4 seconds.

instead of frobbing the registers directly.

As a hack the bcm2835_pwm kmod presently ignores the 'status="disabled"'
in the RPI3 DTB, assuming that if you load the kld you probably
want the PWM to work.
