Has no one tested this on sc8280xp/x13s before merging?
I see a bunch of errors with this series applied to 6.7-rc4:
[ 11.999960] ucsi_glink.pmic_glink_ucsi pmic_glink.ucsi.0: timeout waiting for UCSI sync write response
[ 12.000430] ucsi_glink.pmic_glink_ucsi pmic_glink.ucsi.0: ucsi_handle_connector_change: GET_CONNECTOR_STATUS failed (-110)
[ 17.120515] ucsi_glink.pmic_glink_ucsi pmic_glink.ucsi.0: timeout waiting for UCSI sync write response
[ 17.124204] ucsi_glink.pmic_glink_ucsi pmic_glink.ucsi.0: GET_CONNECTOR_STATUS failed (-110)
[ 23.264792] ucsi_glink.pmic_glink_ucsi pmic_glink.ucsi.0: timeout waiting for UCSI sync write response
[ 23.264953] ucsi_glink.pmic_glink_ucsi pmic_glink.ucsi.0: GET_CONNECTOR_STATUS failed (-110)
Is it just broken or am I missing some undocumented dependency that is
only in linux-next?
