The mlxsw driver relies on NETDEV_CHANGEUPPER events to configure the
device in case a port is enslaved to a master netdev such as bridge or
bond.
Since the driver ignores events unrelated to its ports and their
uppers, it's possible to engineer situations in which the device's data
path differs from the kernel's.
One example to such a situation is when a port is enslaved to a bond
that is already enslaved to a bridge. When the bond was enslaved the
driver ignored the event - as the bond wasn't one of its uppers - and
therefore a bridge port instance isn't created in the device.
Until such configurations are supported forbid them by checking that the
upper device doesn't have uppers of its own.

Do not check which flash type the SoC was booted from before
using this driver. Assume that the device tree is correct and use this
driver when it was added to device tree. This also removes a build
dependency to the SoC code.
All device trees I am aware of only have one correct flash device entry
in it. The device tree is anyway bundled with the kernel in all systems
using device tree I know of.
The boot mode can be specified with some pin straps and will select the
flash type the rom code will boot from. One SPI, NOR or NAND flash chip
can be connect to the EBU and used to load the first stage boot loader
from.

This can cause issues with processes using the poll()
interface:
1) client sends two oneway transactions
2) the second one gets queued on async_todo
(because the server didn't handle the first one
yet)
3) server returns from poll(), picks up the
first transaction and does transaction work
4) server is done with the transaction, sends
BC_FREE_BUFFER, and the second transaction gets
moved to thread->todo
5) libbinder's handlePolledCommands() only handles
the commands in the current data buffer, so
doesn't see the new transaction
6) the server continues running and issues a new
outgoing transaction. Now, it suddenly finds
the incoming oneway transaction on its thread
todo, and returns that to userspace.
7) userspace does not expect this to happen; it
may be holding a lock while making the outgoing
transaction, and if handling the incoming
trasnaction requires taking the same lock,
userspace will deadlock.
By queueing the async transaction to the proc
workqueue, we make sure it's only picked up when
a thread is ready for proc work.

This allows userspace to request death notifications without
having to worry about getting an immediate callback on the same
thread; one scenario where this would be problematic is if the
death recipient handler grabs a lock that was already taken
earlier (eg as part of a nested transaction).

Instead of pushing new transactions to the process
waitqueue, select a thread that is waiting on proc
work to handle the transaction. This will make it
easier to improve priority inheritance in future
patches, by setting the priority before we wake up
a thread.
If we can't find a waiting thread, submit the work
to the proc waitqueue instead as we did previously.

Removes the process waitqueue, so that threads
can only wait on the thread waitqueue. Whenever
there is process work to do, pick a thread and
wake it up. Having the caller pick a thread is
helpful for things like priority inheritance.
This also fixes an issue with using epoll(),
since we no longer have to block on different
waitqueues.

The PowerA gamepad initialization quirk worked with the PowerA
wired gamepad I had around (0x24c6:0x543a), but a user reported [0]
that it didn't work for him, even though our gamepads shared the
same vendor and product IDs.
When I initially implemented the PowerA quirk, I wanted to avoid
actually triggering the rumble action during init. My tests showed
that my gamepad would work correctly even if it received a rumble
of 0 intensity, so that's what I went with.
Unfortunately, this apparently isn't true for all models (perhaps
a firmware difference?). This non-working gamepad seems to require
the real magic rumble packet that the Microsoft driver sends, which
actually vibrates the gamepad. To counteract this effect, I still
send the old zero-rumble PowerA quirk packet which cancels the
rumble effect before the motors can spin up enough to vibrate.

Add early console functionality to the Goldfish tty driver.
When 'earlycon' kernel command line parameter is used with no options,
the early console is determined by the 'stdout-path' property in device
tree's 'chosen' node. This is illustrated in the following device tree
source example:
Device tree example:
chosen {
stdout-path = "/goldfish_tty@1f004000";
};
goldfish_tty@1f004000 {
interrupts = <0xc>;
reg = <0x1f004000 0x0 0x1000>;
compatible = "google,goldfish-tty";
};

Implement tty r/w operations using streaming DMA.
Goldfish tty for Ranchu platforms has been modified to use
streaming DMA mappings for read/write operations. This change
eliminates the need for snooping through the TLB in QEMU using
cpu_get_phys_page_debug() which does not guarantee that it will
return the valid va -> pa mapping.
The streaming DMA mapping is implemented using dma_map_single() per
transfer, while dma_unmap_single() is used for unmapping right after
the DMA transfer.
Using DMA API is the proper way for handling r/w transfers and
makes this driver more portable, thus effectively eliminating
the need for virt_to_page() and page_to_phys() conversions.
This change does not affect the old style Goldfish tty behaviour
which is still used by the Goldfish emulator. Version register has
been added and probed to see which platform is running this driver.
Reading from the new register GOLDFISH_TTY_REG_VERSION using the
Goldfish emulator will return 0 and driver will work with virtual
addresses. Whereas if run on Ranchu it returns 1, and thus DMA is
used.
(Goldfish and Ranchu are code names for the first and the second
generation of virtual boards used by Android emulator.)

Classify constants GOLDFISH_TTY_xxx into two groups: command ids and
register offsets. Apply different naming for register offsets (add
'REG_' after 'GOLDFISH_TTY_' in constant names). Change implementation
to use preprocessor's '#define' statements instead of 'enum'
declaration (as this is more common way of implementation in such
cases).
This makes the driver code easier to follow and hopefully prevents
future bugs.

The .release function of driver_ktype is 'driver_release()'.
This function frees the container_of this kobject.
So, this memory must not be freed explicitly in the error handling path of
'bus_add_driver()'. Otherwise a double free will occur.

Allow the idt_89hpesx driver to get information from child nodes from
both OF and ACPI by using more generic fwnode_property_read*() functions.

Device(IDT0) {

If 'chameleon_get_bar()' fails, we will return 0, which mean success.
We should return the corresponding error code instead.
Remove the useless initialisation of 'ret' which was hiding the issue.
(if 'ret' is not set, gcc generates a warning ("warning: ‘ret’ may be used
uninitialized in this function"))

For now baud field of earlycon structure device is't initialised at all
in of_setup_earlycon (in oppositе to register_earlycon).
So when I use stdout-path to point earlycon device
(like stdout-path = &serial or stdout-path = "serial:115200n8")
baud field of earlycon device structure remains uninitialised and
earlycon initialization is not performed correctly as
of_setup_earlycon is used.
When pass all arguments via bootargs
(like bootargs = "earlycon=uart8250,mmio32,0xf0005000,115200n8")
initialization is performed correctly as register_earlycon is used.
So initialise baud field of earlycon device structure by value of
"current-speed" property from device tree or from options
(if they exist) when we use of_setup_earlycon

Checking for CONFIG_FB_DEFERRED_IO is not the right thing to do since
the fbdev code may be built as a module while vboxvideo is builtin.
This can only happen when DRM_KMS_FB_HELPER is not set:
a) DRM_VBOXVIDEO selects DRM_KMS_HELPER
b) DRM_KMS_FB_HELPER depends on DRM_KMS_HELPER
c) DRM_KMS_FB_HELPER selects FB_DEFERRED_IO
So when DRM_KMS_FB_HELPER is set and vboxvideo is builtin then
FB_DEFERRED_IO must be builtin too.
This commit moves the #ifdefs around fbdefio code over to
CONFIG_DRM_KMS_FB_HELPER, as other drm drivers already do, fixing:
drivers/staging/vboxvideo/vbox_fb.o: In function `vbox_fbdev_fini':
vbox_fb.c:(.text+0x36): undefined reference to `fb_deferred_io_cleanup'
