Emmanuel Vadot be82b3a0bf clk: Move clock code in dev/clk
We've removed kernel option EXT_RESOURCES almost two years ago.
While it was ok to have some code under a common 'extres' subdirectory
at first, we now have a lot of consumer of it and we made it mandatory
so no need to have it under a cryptic name.

Emmanuel Vadot 4c52dde5bd if_cgem: Rewrite clock part
- pclk and hclk are mandatory so always try to get them.
   Don't make it fatal if it fails as some platform (like Zynq) don't
   have a proper clock driver.
 - Always use pclk for the reference clock.
 - Try to get all the possible clocks and enable them.

Emmanuel Vadot bdbbbbb321 if_cgem: Cleanup compatible and add new ones
- Remove cdns,gem, it's the generic binding but for all platform that include
  this one we need specific drivers setup so remove it.
- Remove cdns,macb, it's the generic binding for Atmel AT91 which we don't suport
- Remove cadence,gem, it's not an official binding and seems to be only used in some
  obscure ARM11 SoC.
- Note that the cdns,zynq* are deprecated
- Add the new Xilinx compatible for zynq and zynqmp

As the PolarFire SoC needs SGMII to connect the PHY, check the

appropriately.

Add the compatible strings for the PolarFire SoC device tree.
'microchip,mpfs-mss-gem" is not officially documented but has been
observed in the available firmware for this platform, so it is included
for now.

Also, fix a typo in if_cgem_hw.h.

Mitchell Horne 04d2d2d7fd cgem: improve usage of busdma(9) KPI
BUS_DMA_NOCACHE should only be used when one needs to guarantee the
created mapping has uncached memory attributes, usually as a result
of buggy hardware. Normal use cases should pass BUS_DMA_COHERENT, to
create an appropriate mapping based on the flags passed to
bus_dma_tag_create().

This should have no functional change, since the DMA tags in this driver
are created without the BUS_DMA_COHERENT flag.

This is mostly indentation whitespace, and reflowing a few multiline

for style don't clutter up the diffs for some upcoming functional changes.

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

Pedro F. Giffuni 718cf2ccb9 sys/dev: further adoption of SPDX licensing ID tags.
Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

Ian Lepore 0f822edead Fix the Zedboard/Zynq ethernet driver to handle media speed changes so
that it can connect to switches at speeds other than 1gb.

This requires changing the reference clock speed.  Since we still don't
have a general clock API that lets a SoC-independant driver manipulate its
own clocks, this change includes a weak reference to a routine named
cgem_set_ref_clk().  The default implementation is a no-op; SoC-specific
code can provide an implementation that actually changes the speed.

- Add missing calls to bus_dmamap_unload() in et(4).
- Check the bus address against 0 to decide when to call
  bus_dmamap_unload() instead of comparing the bus_dma map against NULL.
- Check the virtual address against NULL to decide when to call
  bus_dmamem_free() instead of comparing the bus_dma map against NULL.
- Don't clear bus_dma map pointers to NULL for static allocations.
  Instead, treat the value as completely opaque.
- Pass the correct virtual address to bus_dmamem_free() in wpi(4) instead
  of trying to free a pointer to the virtual address.
