Subject: Re: [PATCH 4/5] usb: typec: fusb302: Tell SOP' messages apart from SOP
Date: Tue, 03 Nov 2026 11:47:21 +0000 [thread overview]
Message-ID: <sashiko-outbox-195186@kernel.org> (raw)
In-Reply-To: <20261103-husb311-cable-comm-v1-4-6217dabc1a85@flipper.net>
> The driver sends every message with the SOP ordered set and reports
> every received one as SOP, which leaves TCPM no way to reach the cable
> plug. Start a message with the SOP' ordered set when TCPM asks for it,
> and report a received message as SOP' when its RX FIFO token says so.
>
> SOP' is Sync-1, Sync-1, Sync-3, Sync-3 in USB PD. The Sync-3 TX token
> and the RX FIFO token codes are from the token tables of the FUSB302B
> datasheet.
>
> Nothing changes yet: TCPM asks for SOP' only from a port that claims
> cable communication, and the chip drops SOP' packets until ENSOP1 is
> set.
