This partially reverts c0f3b8643a6fa2461d70760ec49d21d2b031d611.
The "armada370-nand" compatible support is not complete, and it was mistake
to add it. Revert it and postpone the support until the infrastructure is
in place.

If a muxed i2c bus gets created the default retry count and
timeout of the muxed bus is zero. Hence it it possible that you
end up with a situation where the parent controller sets a default
retry count and timeout which gets applied and used while the muxed
bus (using the same controller) has a default retry count of zero
and a default timeout of 1s (set in i2c_add_adapter()). This can be
solved by initializing the retry count and timeout of the muxed
bus with the values used by the the parent at creation time.

There is a mistake in checking the gso_prefix mask when passing large
packets to a guest. The wrong shift is applied to the bit - the raw skb
gso type is used rather then the translated one. This leads to large packets
being handed to the guest without the GSO metadata. This patch fixes the
check.
The mistake manifested as errors whilst running Microsoft HCK large packet
offload tests between a pair of Windows 8 VMs. I have verified this patch
fixes those errors.

This patch changes the RING_FINAL_CHECK_FOR_REQUESTS in
xenvif_build_tx_gops to a check for RING_HAS_UNCONSUMED_REQUESTS as the
former call has the side effect of advancing the ring event pointer and
therefore inviting another interrupt from the frontend before the napi
poll has actually finished, thereby defeating the point of napi.
The event pointer is updated by RING_FINAL_CHECK_FOR_REQUESTS in
xenvif_poll, the napi poll function, if the work done is less than the
budget i.e. when actually transitioning back to interrupt mode.

netback seems to be somewhat confused about the napi budget parameter. The
parameter is supposed to limit the number of skbs processed in each poll,
but netback has this confused with grant operations.
This patch fixes that, properly limiting the work done in each poll. Note
that this limit makes sure we do not process any more data from the shared
ring than we intend to pass back from the poll. This is important to
prevent tx_queue potentially growing without bound.

The W83L786NG stores the fan speed on 4 bits while the sysfs interface
uses a 0-255 range. Thus the driver should scale the user input down
to map it to the device range, and scale up the value read from the
device before presenting it to the user. The reserved register nibble
should be left unchanged.

Call of_dma_controller_register() so that DMA clients can look up the
Tegra DMA controller using standard APIs. This requires the of_xlate()
function to save off the DMA slave ID, and for tegra_dma_slave_config()
not to over-write this information; once DMA client drivers are converted
to dma_request_slave_channel() and DT-based lookups, they won't set this
field of struct dma_slave_config anymore.

The old Tegra-specific API used a struct clock to represent the module

far, the driver exposes the clock feature via the common clock API and

reset implementation will be removed once all drivers have been

Removed the shared ei_debug variable. Replaced it by adding u32 msg_enable to
the private struct ei_device. Now each 8390 ethernet instance has a per-device
logging variable.
Changed older style printk() calls to more canonical forms.
Tested on: ne, ne2k-pci, smc-ultra, and wd hardware.
V4.0
- Substituted pr_info() and pr_debug() for printk() KERN_INFO and KERN_DEBUG
V3.0
- Checked for cases where pr_cont() was most appropriate choice.
- Changed module parameter from 'debug' to 'msg_enable' because debug was
no longer the best description.
V2.0
- Changed netif_msg_(drv|probe|ifdown|rx_err|tx_err|tx_queued|intr|rx_status|hw)

skb_partial_csum_set requires that the linear area of the skb covers the
checksum field. The checksum setup code in netback was only doing that
pullup in the case when the pseudo header checksum was being recalculated
though. This patch makes that pullup unconditional. (I pullup the whole
transport header just for simplicity; the requirement is only for the check
field but in the case of UDP this is the last field in the header and in the
case of TCP it's the last but one).
The lack of pullup manifested as failures running Microsoft HCK network
tests on a pair of Windows 8 VMs and it has been verified that this patch
fixes the problem.

Fix the issue by parsing the necessary configuration like the
