Fabio Aiuto 47ce45906c usb: dwc3: leave default DMA for PCI devices 
in case of a PCI dwc3 controller, leave the default DMA
mask. Calling of a 64 bit DMA mask breaks the driver on
cherrytrail based tablets like Cyberbook T116.

Fixes: 45d39448b4 ("usb: dwc3: support 64 bit DMA in platform driver")

Fabio Aiuto 968bd3f038 extcon: extcon-axp288: Use P-Unit semaphore lock for register accesses 
use low level P-Unit semaphore lock for axp288 register
accesses directly and for more than one access a time,
to reduce the number of times this semaphore is locked
and released which is an expensive operation.

i2c-bus to the XPower is shared between the kernel and the
SoCs P-Unit. The P-Unit has a semaphore wich the kernel must
lock for axp288 register accesses. When the P-Unit semaphore
is locked CPU and GPU power states cannot change or the system
will freeze.

The P-Unit semaphore lock is already managed inside the regmap
access logic, but for each access the semaphore is locked and
released. So use directly iosf_mbi_(un)block_punit_i2c_access(),
we are safe in doing so because nested calls to the same
semaphore are turned to nops.

This happens because when we enqueue a frame for
transmission we do it under xmit_priv lock, then calling
rtw_get_stainfo (needed for enqueuing) takes sta_hash_lock
and this leads to the following lock dependency:

xmit_priv->lock -> sta_hash_lock

Turning off a connection will bring to call
rtw_free_assoc_resources which will set up
the inverse dependency:

sta_hash_lock -> xmit_priv_lock

This could lead to a deadlock as lockdep complains.

Fix it by removing the xmit_priv->lock around
rtw_xmitframe_enqueue call inside rtl8723bs_hal_xmit
and put it in a smaller critical section inside
rtw_xmit_classifier, the only place where
xmit_priv data are actually accessed.

Replace spin_{lock,unlock}_bh(pxmitpriv->lock)
in other tx paths leading to rtw_xmitframe_enqueue
call with spin_{lock,unlock}_bh(psta->sleep_q.lock)
- it's not clear why accessing a sleep_q was protected
by a spinlock on xmitpriv->lock.

This way is avoided the same faulty lock nesting
order.

Extra changes in v2 by Hans de Goede:
-Lift the taking of the struct __queue.lock spinlock out of
 rtw_free_xmitframe_queue() into the callers this allows also
 protecting a bunch of related state in rtw_free_stainfo():
-Protect psta->sleepq_len on rtw_free_xmitframe_queue(&psta->sleep_q);
-Protect struct tx_servq.tx_pending and tx_servq.qcnt when
 calling rtw_free_xmitframe_queue(&tx_servq.sta_pending)
-This also allows moving the spin_lock_bh(&pxmitpriv->lock); to below
 the sleep_q free-ing code, avoiding another ABBA locking issue

This happens because when we enqueue a frame for
transmission we do it under xmit_priv lock, then calling
rtw_get_stainfo (needed for enqueuing) takes sta_hash_lock
and this leads to the following lock dependency:

xmit_priv->lock -> sta_hash_lock

Turning off a connection will bring to call
rtw_free_assoc_resources which will set up
the inverse dependency:

sta_hash_lock -> xmit_priv_lock

This could lead to a deadlock as lockdep complains.

Fix it by removing the xmit_priv->lock around
rtw_xmitframe_enqueue call inside rtl8723bs_hal_xmit
and put it in a smaller critical section inside
rtw_xmit_classifier, the only place where
xmit_priv data are actually accessed.

Replace spin_{lock,unlock}_bh(pxmitpriv->lock)
in other tx paths leading to rtw_xmitframe_enqueue
call with spin_{lock,unlock}_bh(psta->sleep_q.lock)
- it's not clear why accessing a sleep_q was protected
by a spinlock on xmitpriv->lock.

This way is avoided the same faulty lock nesting
order.

This happens because the wrapping function _rtw_init_queues()
bring lockdep considering all queues as a single one. But
all queues are different with their own lock.

Applied the following semantic patch:

expression a;

-       _rtw_init_queue(&a);
+       INIT_LIST_HEAD(&a.queue);
+       spin_lock_init(&a.lock);

Fabio Aiuto 658dfbec96 staging: rtl8723bs: remove unused BIT macros definitions 
BIT(x) macro used all over the driver is defined in
include/vsdo/bit.h as

	- #define BIT(nr)	(UL(1) << (nr))

which is safer than the local BIT macros declared.
Local macros shift a signed integer which brings
unespected results. For example:

(unsigned long)(1 << 31) => 0xffffffff80000000

shift.c:

int main() {
        printf("%lx\n", (unsigned long)(1 << 31));
        printf("%lx\n", (unsigned long)(1U << 31));
        return 0;
}

...

$ ./shift
ffffffff80000000
80000000

...

So just remove redundant, less safe macro declarations.

works only on 2.4Ghz band so there's no need to check which
band we are on. Removed all code branches that would be valid
only for 5Ghz for it's dead code. Removed enums, table fields
indexing by band type, function arguments passing current
band type and all other thing related to telling us
which band we are on.

Fabio Aiuto 7d5fd85ea8 staging: rtl8723bs: rename enum items related to channel bonding 
since rtl8723bs card allows only 20Mhz and 40Mhz channels,
rename enum items related to channel bonding accordingly to
the only composite channel bandwidth allowed in 2.4Ghz
(i.e. 40Mhz) in a HT context (since VHT isn't supported)

Example:

VHT_DATA_SC_20_LOWER_OF_80MHZ ->
	HT_DATA_SC_LOWER_OF_40MHZ

Module parameter rtw_bw_mode can only have two

the default value setting to zero the 5Ghz nibble.
