Subject: [PATCH v2 0/2] usb: typec: tcpm: Make tSenderResponse timer configurable
Date: Sat, 10 Oct 2026 01:37:36 +0000 [thread overview]
Message-ID: <20261010-tcpm-sender-response-time-v2-0-67ea364a21d7@google.com> (raw)
TCPM currently uses a fixed, relaxed tSenderResponse value of 60 ms
(PD_T_SENDER_RESPONSE) for all typec ports. This series adds an
optional "sender-response-time-ms" connector property so that platforms
can specify a different value. Ports that don't specify the property
continue to use 60 ms, so the existing behavior is unchanged.
Dependencies:
Patch 2 ("usb: typec: tcpm: Allow configuring tSenderResponse via
fwnode") depends on patch 1 ("dt-bindings: connector: Add time property
for tSenderResponse"), as patch 1 documents the property that patch 2
parses.
Signed-off-by: Amit Sunil Dhamne <amitsd@google.com>

Changes in v2:
- Added minimum, maximum & default constraints to the dt property.
