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.

2022-06-22arm64: dts: mediatek: mt6795: Add watchdog node to avoid timeoutsAngeloGioacchino Del Regno
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.

2022-06-05bluetooth: don't use bitmaps for random flag accessesLinus Torvalds
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.

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.
