[PATCH v1 0/3] Support patches for Raspberry Pi boards

[PATCH v1 0/3] Support patches for Raspberry Pi boards

[Dave Jones]

These patches are derived from Raspbian's bluez variant and implement
support for the Bluetooth modules found in the Raspberry Pi boards up to
and including the Pi 400, and the two UARTs that can be used to
communicate with them.

If these would be better submitted as individual threads, or as a single
monolithic patch, please let me know - I'm happy to revise things!

  hciattach: Add BCM43xx 3-wire variant
  bdaddr: Treat Cypress devices as Broadcom
  hciattach: Enable loading BCM43xx firmware on RPi

[PATCH v1 1/3] hciattach: Add BCM43xx 3-wire variant

[Dave Jones]

Adds the bcm43xx-3wire variant to the hciattach tool; this is for use
when the Raspberry Pi's mini-UART (which lacks flow-control) is used
instead of the PL011 UART to drive the bluetooth module.

[PATCH v1 2/3] bdaddr: Treat Cypress devices as Broadcom

[Dave Jones]

Adds an entry to cause bdaddr to treat Cypress Semiconductor devices as
Broadcom devices; Cypress (vendor ID 305) acquired Broadcom's (vendor ID
15) wireless division in 2016.

[PATCH v1 3/3] hciattach: Enable loading BCM43xx firmware on RPi

[Dave Jones]

Corrects the location of the firmware from /etc/firmware to
/lib/firmware, and disables setting the UART interface speed prior to
loading the firmware. An already existing later call to
bcm43xx_set_speed still sets the speed of the interface as requested.

For certain bluetooth devices, in particular that on the Raspberry Pi
400, setting the UART speed prior to loading the firmware causes the
firmware load to fail.
