Create new directory to contain all Texas Instruments specific DAI,
platform and machine drivers instead of scattering them under davinci and
omap directories.
There is already inter dependency between the two directories becasue of
McASP (on dra7x it is serviced by sDMA, not EDMA).
With the upcoming AM654 we will need to introduce new platform driver for
UDMA and it does not fit under davinci, nor under omap.
With the move I have restructured the Kconfig to be more usable in the era
of simple-sound-card:
CPU DAIs can be selected individually and they will select the platform
driver they can be served with.
To avoid breakage, I have moved over deprecated Kconfig options so
defconfig builds will work without regression.

Recently TXQ teardown was moved earlier in ieee80211_unregister_hw(),
to avoid a use-after-free of the netdev data. However, interfaces
aren't fully removed at the point, and cfg80211_shutdown_all_interfaces
can for example, TX a deauth frame. Move the TXQ teardown to the
point between cfg80211_shutdown_all_interfaces and the free of
netdev queues, so we can be sure they are torn down before netdev
is freed, but after there is no ongoing TX.

There are systems in which non-wakeup GPEs fire during the "noirq"
suspend stage of suspending devices and that effectively prevents the
system that tries to suspend to idle from entering any low-power
state at all. If the offending GPE fires regularly and often enough,
the system appears to be suspended, but in fact it is in a tight loop
over "noirq" suspend and "noirq" resume of devices all the time.
To prevent that from happening, disable all non-wakeup GPEs except
for the EC GPE for suspend-to-idle (the EC GPE is special, because
on some systems it has to be enabled for power button wakeup events
to be generated as expected).

Signed-off-by: Mimi Zohar <zohar@linux.ibm.com>
Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
The code uses a bitmap to check for duplicate tokens during parsing, and
that doesn't work at all for the negative Opt_err token case.
There is absolutely no reason to make Opt_err be negative, and in fact
it only confuses things, since some of the affected functions actually
return a positive Opt_xyz enum _or_ a regular negative error code (eg
-EINVAL), and using -1 for Opt_err makes no sense.
There are similar problems in ima_policy.c and key encryption, but they
don't have the immediate bug wrt bitmap handing, and ima_policy.c in
particular needs a different patch to make the enum values match the
token array index. Mimi is sending that separately.

The dma_direct_supported() function intends to check the DMA mask against
specific values. However, the phys_to_dma() function includes the SME
encryption mask, which defeats the intended purpose of the check. This
results in drivers that support less than 48-bit DMA (SME encryption mask
is bit 47) from being able to set the DMA mask successfully when SME is
active, which results in the driver failing to initialize.
Change the function used to check the mask from phys_to_dma() to
__phys_to_dma() so that the SME encryption mask is not part of the check.

The signal delivery path of posix-timers can try to rearm the timer even if
the interval is zero. That's handled for the common case (hrtimer) but not
for alarm timers. In that case the forwarding function raises a division by
zero exception.
The handling for hrtimer based posix timers is wrong because it marks the
timer as active despite the fact that it is stopped.
Move the check from common_hrtimer_rearm() to posixtimer_rearm() to cure
both issues.

Commit f6aa5beb45be ("serial: 8250: Fix clearing FIFOs in RS485 mode
again") makes a change to FIFO clearing code which its commit message
suggests was intended to be specific to use with RS485 mode, however:
1) The change made does not just affect __do_stop_tx_rs485(), it also
affects other uses of serial8250_clear_fifos() including paths for
starting up, shutting down or auto-configuring a port regardless of
whether it's an RS485 port or not.
2) It makes the assumption that resetting the FIFOs is a no-op when
FIFOs are disabled, and as such it checks for this case & explicitly
avoids setting the FIFO reset bits when the FIFO enable bit is
clear. A reading of the PC16550D manual would suggest that this is
OK since the FIFO should automatically be reset if it is later
enabled, but we support many 16550-compatible devices and have never
required this auto-reset behaviour for at least the whole git era.
Starting to rely on it now seems risky, offers no benefit, and
indeed breaks at least the Ingenic JZ4780's UARTs which reads
garbage when the RX FIFO is enabled if we don't explicitly reset it.
3) By only resetting the FIFOs if they're enabled, the behaviour of
serial8250_do_startup() during boot now depends on what the value of
FCR is before the 8250 driver is probed. This in itself seems
questionable and leaves us with FCR=0 & no FIFO reset if the UART
was used by 8250_early, otherwise it depends upon what the
bootloader left behind.
4) Although the naming of serial8250_clear_fifos() may be unclear, it
is clear that callers of it expect that it will disable FIFOs. Both
serial8250_do_startup() & serial8250_do_shutdown() contain comments
to that effect, and other callers explicitly re-enable the FIFOs
after calling serial8250_clear_fifos(). The premise of that patch
that disabling the FIFOs is incorrect therefore seems wrong.
For these reasons, this reverts commit f6aa5beb45be ("serial: 8250: Fix
clearing FIFOs in RS485 mode again").

Some eMMCs from Micron have been reported to need ~800 ms timeout, while
enabling the CACHE ctrl after running sudden power failure tests. The
needed timeout is greater than what the card specifies as its generic CMD6
timeout, through the EXT_CSD register, hence the problem.
Normally we would introduce a card quirk to extend the timeout for these
specific Micron cards. However, due to the rather complicated debug process
needed to find out the error, let's simply use a minimum timeout of 1600ms,
the double of what has been reported, for all cards when enabling CACHE
ctrl.

In commit 5320226a0512 ("mmc: core: Disable HPI for certain Hynix eMMC
cards"), then intent was to prevent HPI from being used for some eMMC
cards, which didn't properly support it. However, that went too far, as
even BKOPS and CACHE ctrl became prevented. Let's restore those parts and
allow BKOPS and CACHE ctrl even if HPI isn't supported.

During a re-initialization of the eMMC card, we may fail to re-enable HPI.
In these cases, that isn't properly reflected in the card->ext_csd.hpi_en
bit, as it keeps being set. This may cause following attempts to use HPI,
even if's not enabled. Let's fix this!

While booting with rootfs on MMC, the following warning is encountered
on OMAP4430:
omap-dma-engine 4a056000.dma-controller: DMA-API: mapping sg segment longer than device claims to support [len=69632] [max=65536]
This is because the DMA engine has a default maximum segment size of 64K
but HSMMC sets:
mmc->max_blk_size = 512; /* Block Length at max can be 1024 */
mmc->max_blk_count = 0xFFFF; /* No. of Blocks is 16 bits */
mmc->max_req_size = mmc->max_blk_size * mmc->max_blk_count;
mmc->max_seg_size = mmc->max_req_size;
which ends up telling the block layer that we support a maximum segment
size of 65535*512, which exceeds the advertised DMA engine capabilities.
Fix this by clamping the maximum segment size to the lower of the
maximum request size and of the DMA engine device used for either DMA
channel.

According to the documentation in include/uapi/asm-generic/ioctl.h,
_IOW means userspace is writing and kernel is reading, and
_IOR means userspace is reading and kernel is writing.
In case of these two ioctls, kernel is writing and userspace is reading,
so they have to be _IOR instead of _IOW.
