Certain Broadcom bluetooth chips (bcm4377/bcm4378/bcm438) need ACL streams carrying audio to be set as "high priority" using a vendor specific command to prevent 10-ish second-long dropouts whenever something does a device scan. This patch sends the command when the socket priority is set to TC_PRIO_INTERACTIVE, as BlueZ does for audio. Signed-off-by: Sasha Finkelstein <fnkl.kernel@gmail.com>
The current approach of silently disabling all rust drivers if the toolchain is missing results in users that try to compile their own kernels getting a "successful" build and then being confused about where did their drivers go. In comparison, missing openssl results in a build failure, not a disappearance of everything that depends on it. This also means that allyesconfig will depend on rust, but since the rust experiment concluded with "rust is here to stay", i believe that allyesconfig should be building rust drivers too.

Apple M3 Pro and Max devices are using 'gp00' keys for GPIO in addition to 'gP00' keys. Add a second compatible to handle this keys with an additional macsmc-gpio instance. Signed-off-by: Janne Grunau <j@jannau.net>
Add support for SMC GPIO keys with a lower letter 'p' via the "apple,smc-low-gpio" compatible. This adds support for a second macsmc-gpio controller using 'gp00' keys. These keys are used on Apple M3 Pro and Max MacBooks in the controller for keyboard and trackpad and for the built-in DisplayPort to HDMI converter. Signed-off-by: Janne Grunau <j@jannau.net>

The IRQ fires as soon as the reply is available, which is usually takes a few us instead of the 10ms sleep interval for polling Signed-off-by: Alba Mendez <me@alba.sh> Signed-off-by: Sasha Finkelstein <k@chaosmail.tech>

Add support for sn201202x (aka ACE3), a tipd variant that uses a very similar register map, that is exposed over a "logical register" interface on the SPMI bus.
