Subject: [PATCH] dt-bindings: extcon: tusb320: add SGM7220 fallback compatible
Date: Sat, 10 Oct 2026 16:19:06 +0800 [thread overview]
Message-ID: <20261010081907.479226-1-jerrysteve1101@gmail.com> (raw)
The SGM7220 is register-compatible with the TI TUSB320, even reporting
the same device ID, so it can be described in a device tree using
ti,tusb320 as the fallback compatible string.
