      net: amd: a2065: Use print_hex_dump_debug() helper · e07c5f2e
      由 Geert Uytterhoeven 提交于 
      Use the print_hex_dump_debug() helper, instead of open-coding the same
operations.

      Merge branch 'IXP4xx-networking-cleanups' · cbd19d09
      由 Jakub Kicinski 提交于 
      Linus Walleij says:

====================
IXP4xx networking cleanups

This is a patch series which jams together Arnds and mine
cleanups for the IXP4xx networking.

I also have patches for device tree support but that
requires more elaborate work, this series is some of
mine and some of Arnds patches that is a good foundation
for his multiplatform work and my device tree work.

These are for application to the networking tree so
that can be taken in one separate sweep.

I have tested the patches for a bit using zeroday builds
and some boots on misc IXP4xx devices and haven't run
into any major problems. We might find some new stuff
as a result from the new compiler coverage.

I had to depromote enabling compiler coverage at one
point in the v2 set because it depended on other patches
making the code more generic.

The change in v3 was simply dropping one offending
patch hardcoding base addresses into the driver.

The change in v4 drops a stable@ tag that was
unnecessary.

This v5 is a rebase of the v4 patch set on top of
net-next.

      net: ethernet: ixp4xx: Use parent dev for DMA pool · e45d0fad
      由 Linus Walleij 提交于 
      Use the netdevice struct device .parent field when calling
dma_pool_create(): the .dma_coherent_mask and .dma_mask
pertains to the bus device on the hardware (platform)
bus in this case, not the struct device inside the network
device. This makes the pool allocation work.

      ARM/net: ixp4xx: Pass ethernet physical base as resource · f458ac47
      由 Linus Walleij 提交于 
      In order to probe this ethernet interface from the device tree
all physical MMIO regions must be passed as resources. Begin
this rewrite by first passing the port base address as a
resource for all platforms using this driver, remap it in
the driver and avoid using any reference of the statically
mapped virtual address in the driver.

      Use "ndev" for the struct net_device and "dev" for the

"dev" pointer for later use in refactoring.

Take this opportunity to fix inverse christmas tree

      net: ethernet: ixp4xx: Standard module init · c83db9ef
      由 Linus Walleij 提交于 
      The IXP4xx driver was initializing the MDIO bus before even
probing, in the callbacks supposed to be used for setting up
the module itself, and with the side effect of trying to
register the MDIO bus as soon as this module was loaded or
compiled into the kernel whether the device was discovered
or not.

This does not work with multiplatform environments.

To get rid of this: set up the MDIO bus from the probe()
callback and remove it in the remove() callback. Rename
the probe() and remove() calls to reflect the most common
conventions.

Since there is a bit of checking for the ethernet feature
to be present in the MDIO registering function, making the
whole module not even be registered if we can't find an
MDIO bus, we need something similar: register the MDIO
bus when the corresponding ethernet is probed, and
return -EPROBE_DEFER on the other interfaces until this
happens. If no MDIO bus is present on any of the
registered interfaces we will eventually bail out.

None of the platforms I've seen has e.g. MDIO on EthB
and only uses EthC, there is always a Ethernet hardware
on the NPE (B, C) that has the MDIO bus, we just might
have to wait for it.
