Revision 81a87b6697876855f7ec19cde74d6836b380d58d authored by Stefan Wahren on 06 October 2019, 15:28:19 UTC, committed by popcornmix on 13 July 2020, 12:27:19 UTC
commit 3347a80965b38f096b1d6f995c00c9c9e53d4b8b upstream. The RPi 4 uses the hardware handshake lines for CYW43455, but the chip doesn't react to HCI requests during DT probe. The reason is the inproper handling of the RTS line during startup. According to the startup signaling sequence in the CYW43455 datasheet, the hosts RTS line must be driven after BT_REG_ON and BT_HOST_WAKE.
