USB PD specification defines a bunch of timers that can have a range of acceptable values instead of specific values. These values have to be tuned based on the platform. However, TCPM currently sets them to a default value without providing a mechanism to set platform specific values. This patchset adds new DT properties per timer to allow users to define platform specific values. Changes compare to v2: - Added min, max & default values to DT property in Documentation. - Changed return type of tcpm_fw_get_timings to void instead of int. Changes compared to v1: - Defined new properties per timer that we are interested in rather than defining a single pd-timers u32 array property. - Better description of the timer properties. - Since subject has changed, adding link for previous patchset for posterity: https://lore.kernel.org/all/20240911000715.554184-1-amitsd@google.com/ Amit Sunil Dhamne (2): dt-bindings: connector: Add properties to define time values usb: typec: tcpm: Add support for parsing time dt properties .../bindings/connector/usb-connector.yaml | 35 ++++++++- drivers/usb/typec/tcpm/tcpm.c | 74 +++++++++++++++---- 2 files changed, 92 insertions(+), 17 deletions(-) base-commit: 68d4209158f43a558c5553ea95ab0c8975eab18c
