ef4e6c8fe8 Fix access to cpu_model[] in mtk_soc_set_cpu_model()
There may be cases where cpu_model[] may not be 32bit aligned, so it is
better to not try to access it as such in order to avoid unaligned access.

3154bc4680 Implement support for sysctl hw.model for Mediatek/Ralink SoCs
These SoCs have CHIPID registers, which store the Chip model, according
to the manufacturer; make use of those in order to better identify
the chip we're actually running on.

If we're unable to read the CHIPID registers for some reason we will
use the string "unknown " as a value for hw.model.

f7604b1b27 Align OF_getencprop_alloc API with OF_getencprop and OF_getprop_alloc
Change OF_getencprop_alloc semantics to be combination of malloc and
OF_getencprop and return size of the property, not number of elements
allocated.

For the use cases where number of elements is preferred introduce
OF_getencprop_alloc_multi helper function that copies semantics
of OF_getencprop_alloc prior to this change.

This is to make OF_getencprop_alloc and OF_getencprop_alloc_multi
function signatures consistent with OF_getencprop_alloc and
OF_getencprop_alloc_multi.

Functionality-wise this patch is mostly rename of OF_getencprop_alloc
to OF_getencprop_alloc_multi except two calls in ofw_bus_setup_iinfo
where 1 was used as a block size.

217d17bcd3 Clean up OF_getprop_alloc API
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.

d3bf5efc1f Fix device delete child function.
When detaching device trees parent devices must be detached prior to
detaching its children. This is because parent devices can have
pointers to the child devices in their softcs which are not
invalidated by device_delete_child(). This can cause use after free
issues and panic().

Device drivers implementing trees, must ensure its detach function
detaches or deletes all its children before returning.

While at it remove now redundant device_detach() calls before
device_delete_child() and device_delete_children(), mostly in
the USB controller drivers.

32f8bbf8cd Add proper PCIe init for MT7628/MT7688 SoCs
PCIe PHY needs different initialization on MT7628/MT7688 SoCs than it does
on MT7620.
However, LEDE (and OpenWRT) dts files have the PCIe node for MT7628/MT7688
as compatible with mt7620-pci.
We already can handle this properly in our driver, so we just need to add
compat strings to fbsd-mt7628an.dtsi and the PCIe driver.

cd642c88a1 INTRNG - redefine struct intr_map_data to avoid headers pollution. Each
struct associated with some type defined in enum intr_map_data_type
must have struct intr_map_data on the top of its own definition now.
When such structs are used, correct type and size must be filled in.

There are three such structs defined in sys/intr.h now. Their
definitions should be moved to corresponding headers by follow-up
commits.

While this change was propagated to all INTRNG like PICs,
pic_map_intr() method implementations were corrected on some places.
For this specific method, it's ensured by a caller that the 'data'
argument passed to this method is never NULL. Also, the return error
values were standardized there.

83089b1b11 Remove uart_dev_mtk_ns8250
The purpose of this file was to simply detect the UART speed before
attaching the actual ns8250 driver so that we don't have to specify the
UART speed in DTS files.

However, OpenWRT DTS files specify ns16550a as a compatible string in
their DTS files and this makes the original ns8250 driver attach to
the device. So we would have to edit the DTS files anyway and since this
is only the case for MT7621 and MT7628/MT7688 for now, it's better to
just add the clock-frequency property to those (UART is always clocked
by the same clock in both these SoCs, so that's fine) instead of having
a separate driver and still having to change the DTS files.

OpenWRT's dts files treat RT3050/RT3052/RT3350 within the same SoC dtsi

because the bit we use to determine the clock speed on RT3050/RT3052

slew rate calibration.
These are the only two SoCs, apart from MT7628, which actually make
use of the slew rate calibration routines implemented in the mtk_usb_phy
driver. Since MT7628 is actually a superset of MT7688 things should be
the same for it as well.

We do not remove the code, we simply define it out.

- uart_dev_mtk_ns8250.c is the new-style ns16550a-compatible UART driver
  found in newer Mediatek SoCs. It uses the uart_dev_ns8250.c driver
  indirectly and is basically just a wrapper around it and only overrides its
  probe method.
  The reason I am not using the uart_dev_ns8250.c driver directly is because
  I have some code that does UART clock detection before initializing the
  UART, so that we don't need to hard-code the UART clock frequency in the
  dts files for each board.

e56e179d55 Initial import of Ralink/Mediatek MIPS SoC support #3
Interrupt controllers found in various Mediatek/Ralink SoCs.

mtk_intr_v1 and mtk_intr_v2 are basically the same at the moment, with
just different register mappings.

However, v1 interrupt controller has a subset of the functionality of the
v2 interrupt controller, so in the future the v2 interrupt controller driver
may be enhanced, if needed, with things like level/edge interrupts and soft
interrupts. So, for the moment I suggest we keep them as 2 separate files.

mtk_intr_gic provides very basic (similar to v1 and v2) support for MIPS GIC
controllers, which currently maps all interrupts to a single core and sets
them to type level, active high. In the future this may be developed into a
generic GIC controller to support any new MIPS SoCs that include it. The GIC
is a standard MTI interrupt controller in their multi-core line-up (e.g.,
1004K, 1074K, etc.), rather than a SoC-specific controller.
