pkgver=4.14.56
core/linux-raspberrypi to 4.14.56-2 (#1605) - The serial device bus was compiled as a module, but this disabled use of the serial device TTY port controller that actually interfaces with the serdev drivers[1], rendering them unusable. Examples include the serdev driver for broadcom bluetooth HCI. - Once built in to the kernel, enabling SERIAL_DEV_CTRL_TTYPORT to be built in, the userspace dependency on btattach is removed and the presence of the bluetooth controller can be indicated in the device tree, instead. This doesn't simply get rid of the dependency on btattach, but improves functionality, as the kernel does not restore the UART link to a higher baud rate after uploading the firmware to the bluetooth controller when notified of the controller over btattach but does so when notified through the device tree. hciattach does restore a higher set baud rate, but that is deprecated. - According to [2], the configuration settings USB_CONFIGFS_F_* are meant for the user to indicate what sort of gadget functionality is to be enabled, while settings USB_F_* are meant to be used in the makefile for compilation. - Enabled USB_CONFIGFS_F_UAC2 at the same time, since UAC1 does not play well when used with a high-speed composite device (UAC1 is not compatible with high-speed, while UAC2 is) - Kernel image size increased by 4008 bytes after these changes 1 - http://events17.linuxfoundation.org/sites/events/files/slides/serdev-elce-2017-2.pdf 2 - https://www.spinics.net/lists/linux-usb/msg142134.html
