Subject: [PATCH v5 1/4] dt-bindings: usb: add documentation for typec switch simple driver
Date: Tue, 3 Nov 2020 19:40:07 +0800 [thread overview]
Message-ID: <1604403610-16577-1-git-send-email-jun.li@nxp.com> (raw)
Some platforms need a simple driver to do some controls according to
typec orientation, this can be extended to be a generic driver with
compatible with "typec-orientation-switch".
Signed-off-by: Li Jun <jun.li@nxp.com>

No changes for v5.
changes on v4:
- Use compatible instead of bool property for switch matching.
- Change switch GPIO to be switch simple.
- Change the active channel selection GPIO to be optional.
