From 3bbb9ba4f66006f27ad0d5ceaf2480117e16d489 Mon Sep 17 00:00:00 2001 From: RD Babiera Date: Mon, 8 Jan 2024 19:16:17 +0000 Subject: usb: typec: tcpci: add tcpm_transmit_type to tcpm_pd_receive tcpm_pd_receive adds the SOP type as a parameter, and passes it within the pd_rx_event struct for tcpm_pd_rx_handler to use. For now, the handler drops all SOP' messages. Maxim based tcpci drivers are capable of SOP' communication, so process_rx now takes the SOP type into account and passes the value to tcpm_pd_receive. tcpci_set_pd_rx now utilizes the cable_comm_capable flag to determine if TCPC_RX_DETECT_SOP1 should be added to the bitfield when enabling PD message reception. For all other consumers of tcpm_pd_receive, default the new field to TCPC_TX_SOP.
