Subject: Re: [PATCH V4 01/10] bluetooth: hci_bcm: Fix RTS handling during startup
Date: Mon, 21 Oct 2019 17:05:32 +0200 [thread overview]
Message-ID: <F722AF4D-B6C8-495E-B4F0-B4DD113C1938@holtmann.org> (raw)
In-Reply-To: <1570375708-26965-2-git-send-email-wahrenst@gmx.net>
Hi Stefan,
> 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.
