Subject: [PATCH 0/2] usb: typec: tcpm: Handle Accessory Modes
Date: Tue, 21 Nov 2023 01:11:06 +0200 [thread overview]
Message-ID: <20231120231757.2309482-1-dmitry.baryshkov@linaro.org> (raw)
In addition to Alternative Modes (see [1]), some of the TCPM-backed
boards (e.g. Qualcomm SM8150-HDK) can support USB-C Accessory Modes
(e.g. the Analog Audio). Add bindings and driver support for parsing
this kind of information.
Note, while it might make sense to put accessory-mode-audio and -debug
handling to typec_get_fw_cap(), I decided against it. Several existing
drivers use this function, while providing AccMode caps based on some
internal logic.
