Subject: [PATCH v2 0/8] arm64: qcom: add Type-C Altmode support
Date: Wed, 07 Jun 2023 10:04:59 +0200 [thread overview]
Message-ID: <20230601-topic-sm8550-upstream-type-c-v2-0-3bbdf37575c3@linaro.org> (raw)
This adds the missing bits to support the USB-C Altmode
support on SM8550.
These are the following changes since the previous SM8450 SoC:
- No more GLINK altmode events for USB only changes, only DP
- Type-C orientation is available on a PMIC signal connected
to a GPIO line
- When altmode is disconnected, an 0xff mode event is sent.
In order to handle those changes, a new orientation-gpios property
is added to the usb-c connector bindings.
The 0xff altomode is translated as a SAFE type-c mux mode.
And in order to handle such info, we tie this to the UCSI connector
events to propagate the orientation to Type-C switches.
Redriver driver & bindings dependency at [1].

Changes in v2:
- Updated redriver node to use retimer-switch on QRD
- Fixed redriver data-lane according to v2 bindings
- Added review/ack tags
- Added new change to handle retimer-switch in pmic-glink altmode driver
- Link to v1: https://lore.kernel.org/r/20230601-topic-sm8550-upstream-type-c-v1-0-d4d97b4d8bab@linaro.org
