The DM365 platform has a strange quirk (only present when using ancient
u-boot - mainline u-boot v2013.01 and later works fine) where if we
enable the second half of the timer in periodic mode before we do its
initialization - the time won't start flowing and we can't boot.
When using more recent u-boot, we can enable the timer, then reinitialize
it and all works fine.
To work around this issue only enable clockevents once tim34 is
initialized i.e. move clockevents_config_and_register() below tim34
initialization.

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.

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.

driver. However, with CONFIG_DRM=y and CONFIG_BACKLIGHT_CLASS_DEVICE=m,
the drm_panel_of_backlight is left out of drm_panel.o but the condition
tells the driver that it is there, leading to multiple link errors such as

With gcc -O3 in combination with the structleak plug, the compiler can
inline very aggressively, leading to rather large stack usage:
drivers/gpu/drm/panel/panel-tpo-td028ttec1.c: In function 'td028ttec1_prepare':
drivers/gpu/drm/panel/panel-tpo-td028ttec1.c:233:1: error: the frame size of 2768 bytes is larger than 2048 bytes [-Werror=frame-larger-than=]
}
Marking jbt_reg_write_*() as noinline avoids the case where
multiple instances of this function get inlined into the same
stack frame and each one adds a copy of 'tx_buf'.
The compiler is clearly making some bad decisions here, but I
did not open a new bug report as this only happens in combination
with the structleak plugin.
This fixes mmtom ("init/Kconfig: enable -O3 for all arches")

In order to avoid spamming the logs, this patch converts the

All timeouts are now handled by a dedicated timeout struct. This
variable is no longer needed.

The adis library only allows to define a `startup_delay` which for some
devices is enough. However, other devices define different timeouts with
significantly different timings which could lead to devices to not wait
enough time or to wait a lot more than necessary (which is not
efficient). This patch introduces a new timeout struct that must be
passed into `adis_init()`. There are mainly, for now, three timeouts
used. This is also an introductory patch with the goal of refactoring
`adis_initial_startup()`. New driver's (eg: adis16480, adis16460) are
replicating code for the device initial setup. With some changes (being
this the first one) we can pass this to `adis_initial_startup()`.

dma_request_slave_channel() is a wrapper on top of dma_request_chan()
eating up the error code.
The dma_request_chan() is the standard API to request slave channel,
clients should be moved away from the legacy API to allow us to retire
them.

By using dma_request_chan() directly the driver can support deferred
probing against DMA.
