9b909db680 arm64: dts: mediatek: asurada: Add keyboard mapping for the top row 
Chromebooks' embedded keyboards differ from standard layouts for the
top row in that they have shortcuts in place of the standard function
keys. Map these keys to achieve the functionality that is pictured on
the printouts.

There's a minor difference between the keys present on Hayato, which
uses an older layout, and Spherion, which uses a newer one.

468deda82f arm64: dts: mediatek: mt6795: Remove incorrect fixed-clocks 
Remove the RTC and UART fixed clocks, as these were introduced to
temporarily provide a dummy clock to devices: since the two 26M/32K
fixed oscillators clocks (which do really exist in the SoC) have
been added, there's no reason to keep the aforementioned (and now
redundant) dummies in this devicetree.

In order to remove the uart dummy clock, it was necessary to also
reassign the clock of all UART nodes to clk26m.

ac4cf9a2e3 arm64: dts: mediatek: mt6795: Add watchdog node to avoid timeouts 
At least on commercial devices like some smartphones, the bootloader
will initialize the SoC watchdog and set it to reboot the board when
it times out. The last pet that this watchdog is getting is right
before booting the kernel and left it enabled as a protection against
boot failure: this means that Linux is expected to initialize this
device and pet as soon as possible, or it will bark and reset the AP.

In order to prevent that, add the required watchdog node as default
enabled: this will have no side effects on boards that are not
performing the aforementioned watchdog setup before booting Linux.

e1cff7002b bluetooth: don't use bitmaps for random flag accesses 
The bluetooth code uses our bitmap infrastructure for the two bits (!)
of connection setup flags, and in the process causes odd problems when
it converts between a bitmap and just the regular values of said bits.

It's completely pointless to do things like bitmap_to_arr32() to convert
a bitmap into a u32.  It shoudln't have been a bitmap in the first
place.  The reason to use bitmaps is if you have arbitrary number of
bits you want to manage (not two!), or if you rely on the atomicity
guarantees of the bitmap setting and clearing.

The code could use an "atomic_t" and use "atomic_or/andnot()" to set and
clear the bit values, but considering that it then copies the bitmaps
around with "bitmap_to_arr32()" and friends, there clearly cannot be a
lot of atomicity requirements.

So just use a regular integer.

In the process, this avoids the warnings about erroneous use of
bitmap_from_u64() which were triggered on 32-bit architectures when
conversion from a u64 would access two words (and, surprise, surprise,
only one word is needed - and indeed overkill - for a 2-bit bitmap).

That was always problematic, but the compiler seems to notice it and
warn about the invalid pattern only after commit 0a97953fd2 ("lib: add
bitmap_{from,to}_arr64") changed the exact implementation details of
'bitmap_from_u64()', as reported by Sudip Mukherjee and Stephen Rothwell.

It used to grab an extra reference to struct file rather than
just transferring to caller the one it had removed from descriptor
table.  New variant doesn't, and callers need to be adjusted.
