dt-bindings: pinctrl: mt8195: Add and use drive-strength-microamp

As was already done for MT8192 in commit b52e695324bb ("dt-bindings:
pinctrl: mt8192: Add drive-strength-microamp"), replace the custom
mediatek,drive-strength-adv property with the standardized pinconf
'drive-strength-microamp' one.

Similarly to the mt8192 counterpart, there's no user of property
'mediatek,drive-strength-adv', hence removing it is safe.

2 years agobluetooth: don't use bitmaps for random flag accesses
Linus Torvalds [Sun, 5 Jun 2022 18:51:48 +0000 (11:51 -0700)]
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 0a97953fd221 ("lib: add
bitmap_{from,to}_arr64") changed the exact implementation details of
'bitmap_from_u64()', as reported by Sudip Mukherjee and Stephen Rothwell.
