_after_ the triggered BUS_OFF event.
In the current CAN state handling code, this will lead to an

clk_set_rate() tries to take clk's prepare_lock mutex while being in atomic
context entered in sdhci_do_set_ios().
The solution is inspired by similar situation in sdhci_set_power() also called
from sdhci_do_set_ios():
spin_unlock_irq(&host->lock);
mmc_regulator_set_ocr(mmc, mmc->supply.vmmc, vdd);
spin_lock_irq(&host->lock);
Note that since sdhci_s3c_set_clock() sets SDHCI_CLOCK_CARD_EN, proposed change
first resets this bit. It is reset anyway (by setting SDHCI_CLOCK_INT_EN bit
only) after call to clk_set_rate() in order to wait for the clock to stabilize
and is set again as soon as the clock becomes stable.

return type of wait_for_completion_timeout is unsigned long not int, this
patch adds an appropriate variable and fixes up the assignment. It removes
the else branch as the only thing it was doing is assigning ret = 0; - but
ret is never used thereafter so that is not needed. As the string in
dev_err already states "timeout" there is little point in printing the 0.
A typo in "trasfer" -> transfer is also fixed.

CR4 manipulation was split, seemingly at random, between direct
(write_cr4) and using a helper (set/clear_in_cr4). Unfortunately,
the set_in_cr4 and clear_in_cr4 helpers also poke at the boot code,
which only a small subset of users actually wanted.
This patch replaces all cr4 access in functions that don't leave cr4
exactly the way they found it with new helpers cr4_set_bits,
cr4_clear_bits, and cr4_set_bits_and_update_boot.

Add support for DRA7xx DPI output.
DRA7xx has three DPI outputs, each of which gets its input from a DISPC
channel. However, DRA72x has only one video PLL, and DRA74x has two
video PLLs. In both cases the video PLLs need to be shared between
multiple outputs. The driver doesn't handle this at the moment.
Also, DRA7xx requires configuring CONTROL module bits to route the clock
from the PLL to the used DISPC channel.

A race issue has been observed with the encoder-tpd12s015 driver, which
leads to errors when trying to read EDID. This has only now been
observed, as OMAP4 and OMAP5 boards used SoC's GPIOs for LS_OE GPIO. On
dra7-evm boards, the LS_OE is behind a i2c controlled GPIO expander,
which increases the time to set the LS_OE.
This patch simplifies the handling of the LS_OE gpio in the driver by
removing the interrupt handling totally. The only time we actually need
to enable LS_OE is when we are reading the EDID, and thus we can just
set and clear the LS_OE gpio inside the read_edid() function.
This also has the additional benefit of very slightly decreasing the
power consumption.

The OMAP5 HW supports directing DIGIT channel to DPI output, but the
driver doesn't support that. However, we have marked that configuration
as possible in the dss features, so in certain cases the driver tries to
use that configuration, leading to broken display.
Fix the problem by allowing DIGIT channel to go only to HDMI output.

drm: Add multi buffer plane pixel formats
which hasn't seen a lot of review really. The problem is that it's not
a real pixel format, but just a different way to lay out NV12 pixels
in macroblocks, i.e. a tiling format.
The new way of doing this is with the soon-to-be-merged fb modifiers.
This was brough up in some long irc discussion around the entire
topic, as an example of where things have gone wrong. Luckily we can
correct the mistake:
- The kms side support for NV12MT is all dead code because
format_check in drm_crtc.c never accepted NV12MT.
- The gem side for the gsc support doesn't look better: The code
forgets to set the pixel format and makes a big mess with the tiling
mode bits, inadvertedly setting them all.
Conclusion: This never really worked (at least not in upstream) and
hence we can safely correct our mistake here.

This patch provides a simple mmc-pwrseq-emmc driver, which controls
single gpio line. It perform standard eMMC hw reset procedure, as
descibed by Jedec 4.4 specification. This procedure is performed just
after MMC core enabled power to the given mmc host (to fix possible
issues if bootloader has left eMMC card in initialized or unknown
state), and before performing complete system reboot (also in case of
emergency reboot call). The latter is needed on boards, which doesn't
have hardware reset logic connected to emmc card and (limited or broken)
ROM bootloaders are unable to read second stage from the emmc card if
the card is left in unknown or already initialized state.

Jonas Jensen wanted to submit a patch for these, but apparently
forgot about it. I stumbled over this symptom first:
drivers/built-in.o: In function `moxart_probe':
:(.text+0x2af128): undefined reference to `of_dma_request_slave_channel'
This is because of_dma_request_slave_channel is an internal helper
and not exported to loadable module. I'm changing the driver to
use dma_request_slave_channel_reason() instead.
Further problems from inspection:
* The remove function must not call kfree on the host pointer,
because it is allocated together with the mmc_host.
* The clock is never released
* The dma_cap_mask_t is completely unused and can be removed
* deferred probing does not work if the dma driver is loaded
after the mmc driver.
This patch should fix all of the above.

The current implementation limits nci_core_conn_create_req()
to only manage NCI_DESTINATION_NFCEE.
Add new parameters to nci_core_conn_create() to support all
destination types described in the NCI specification.
Because there are some parameters with variable size dynamic
buffer allocation is needed.

Older machines with more then 16 domains need a special check before
PQAP instructions can be processed. With commit 5bc334bff9a6e189 this
check was reverted by accident. This patch re-establishes the additional
code needed for checking the extended domains for older machines.

The 3.2 revision has a different target BMI

Introduce an optional log level configuration for the existing debugfs fw_dbglog file. It
allows users to configure the desired log level for firmware dbglog messages.
To configure log level as WARN:
echo 0xffffffff 2 > /sys/kernel/debug/ieee80211/phy0/ath10k/fw_dbglog
The values are:
VERBOSE 0
INFO 1
WARN 2
ERR 3

Otherwise ath10k will just checksum everything even if it did not
go through the TCP/IP stack (for example bridged frames). In the worst
case this could mean recreating the checksum for incorrect data.

Ath10k driver sets wrong default key idx that results in
sending unicast frames with multicast key.
The reason for this behavior is that cached broadcast key
is installed for station MAC address on association. After
dot1x completes, unicast key is installed for station
MAC address. Default key idx is set to broadcast key id when
driver tries to send broadcast frame. This causes firmware
to use broadcast key id to transmit unicast frames to stations.
Used TX_USAGE flag to set default key for stations.
Added callback for setting unicast default idx which will be
invoked on every default key idx configuration.

This reverts commit 3d0ad09412ffe00c9afa201d01effdb6023d09b4.
Now that GSO functionality can correctly track if the fragment
id has been selected and select a fragment id if necessary,
we can re-enable UFO on tap/macvap and virtio devices.

This reverts commit 5188cd44c55db3e92cd9e77a40b5baa7ed4340f7.
Now that GSO layer can track if fragment id has been selected
and can allocate one if necessary, we don't need to do this in
tap and macvtap. This reverts most of the code and only keeps
the new ipv6 fragment id generation function that is still needed.
