Subject[PATCH 05/11] firmware: ti_sci: rm: Add support for extended_ch_type for tx channel
Date
Sysfw added 'extended_ch_type' to the tx_ch_cfg_req message which should be
used when BCDMA block copy channels are configured:
extended_ch_type = 0 : the channel is split tx channel (tchan)
extended_ch_type = 1 : the channel is block copy channel (bchan)
