X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=79dd160c673294a7cc655b8af129ea068bf6528f;p=thirdparty%2Fkernel%2Flinux.git

arm64: dts: qcom: sm8750-mtp: Enable USB headset and Type-C accessory mode

MTP8750 does not have audio jack connected and relies on USB mux
(WCD9395).  Add necessary nodes for proper audio headset support along
with USB Type-C accessory mode and orientation.
