The driver is used only on Exynos based boards with DTS support.
After removal of board file support from max77686 and max77802 regulator
drivers, the MFD driver can be converted to DTS-only version. This
simplifies a little the code:
1. No dead (unused) entries in platform_data structure.
2. More code removed.
3. Regulator driver does not depend on allocated memory
from MFD driver.
4. It makes also easier extending the regulator driver.
Add to the max77686 MFD driver dependency on CONFIG_OF because without
DTS the regulator drivers (max77686 and max77802) won't bind.

Without suspend/resume functionality in the USB driver the USB core
will disconnect and reconnect the DLN2 port and because the GPIO
framework does not yet support removal of an in-use controller a
suspend/resume operation will result in a crash.
This patch provides suspend and resume functions for the DLN2 driver
so that the above scenario is avoided, if the host controller does not
drop VBUS during suspend, since in this case the device state is
preserved.
We chose not implemented reset_resume so that if the host controller
does drop VBUS the resume path will go through above the
disconnect/reconnect process since it is probably better to fix the
GPIO framework disconnect issue then to save and restore the device
state for every driver.

- Avoid platform ID collision in da9052
- Skip caching volatile registers in tps65218
- Use correct address base in tps65218
- Repair deadlock on suspend in rtsx_usb
|

sd_set_power_mode() in derived module drivers/mmc/host/rtsx_usb_sdmmc.c
acquires dev_mutex and then calls pm_runtime_get_sync() to make sure the
device is awake while initializing a newly inserted card. Once it is
called during suspending state and explicitly before rtsx_usb_suspend()
acquires the same dev_mutex, both routine deadlock and further hang the
driver because pm_runtime_get_sync() waits the pending PM operations.
Fix this by using an empty suspend method. mmc_core always turns the
LED off after a request is done and thus it is ok to remove the only
rtsx_usb_turn_off_led() here.

STATUS register can be modified by the HW, so we
should bypass cache because of that.
In the case of INT[12] registers, they are the ones
that actually clear the IRQ source at the time they
are read. If we rely on the cache for them, we will
never be able to clear the interrupt, which will cause
our IRQ line to be disabled due to IRQ throttling.

Modifying a non-existent slot is not allowed. Also check that the
first loop doesn't move a deleted slot beyond the used part of
the mslots array.
Signed-off-by: Paolo Bonzini <[email protected]>

Before commit 0e60b0799fed (kvm: change memslot sorting rule from size
to GFN, 2014-12-01), the memslots' sorting key was npages, meaning
that a valid memslot couldn't have its sorting key equal to zero.
On the other hand, a valid memslot can have base_gfn == 0, and invalid
memslots are identified by base_gfn == npages == 0.
Because of this, commit 0e60b0799fed broke the invariant that invalid
memslots are at the end of the mslots array. When a memslot with
base_gfn == 0 was created, any invalid memslot before it were left
in place.
This can be fixed by changing the insertion to use a ">=" comparison
instead of "<=", but some care is needed to avoid breaking the case
of deleting a memslot; see the comment in update_memslots.
Thanks to Tiejun Chen for posting an initial patch for this bug.

The __ldcw macro has a problem when its argument needs to be reloaded from
memory. The output memory operand and the input register operand both need to
be reloaded using a register in class R1_REGS when generating 64-bit code.
This fails because there's only a single register in the class. Instead, use a
memory clobber. This also makes the __ldcw macro a compiler memory barrier.

Implemented separate stream_tag assignment for input and output streams.
According to hda specification stream tag must be unique throughout the
input streams group, however an output stream might use a stream tag
which is already in use by an input stream. This change is necessary
to support HW which provides a total of more than 15 stream DMA engines
which with legacy implementation causes an overflow on SDxCTL.STRM
field (and the whole SDxCTL register) and as a result usage of
Reserved value 0 in the SDxCTL.STRM field which confuses HDA controller.
