From 1c552e08b29895d31bbf82bdb549811cfde31db4 Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi Date: Sun, 25 Oct 2020 12:10:02 -0700 Subject: firmware: ti_sci: rm: Add support for tx_tdtype parameter for tx channel The system controller's resource manager have support for configuring the TDTYPE of TCHAN_CFG register on j721e. With this parameter the teardown completion can be controlled: TDTYPE == 0: Return without waiting for peer to complete the teardown TDTYPE == 1: Wait for peer to complete the teardown Signed-off-by: Peter Ujfalusi Reviewed-by: Tero Kristo Tested-by: Keerthy Reviewed-by: Grygorii Strashko Signed-off-by: Santosh Shilimkar --- drivers/firmware/ti_sci.c | 1 + drivers/firmware/ti_sci.h | 7 +++++++ 2 files changed, 8 insertions(+) (limited to 'drivers') diff --git a/drivers/firmware/ti_sci.c b/drivers/firmware/ti_sci.c index 896f53ec7857..65a8c2e82093 100644 --- a/drivers/firmware/ti_sci.c +++ b/drivers/firmware/ti_sci.c @@ -2362,6 +2362,7 @@ static int ti_sci_cmd_rm_udmap_tx_ch_cfg(const struct ti_sci_handle *handle, req->fdepth = params->fdepth; req->tx_sched_priority = params->tx_sched_priority; req->tx_burst_size = params->tx_burst_size; + req->tx_tdtype = params->tx_tdtype; ret = ti_sci_do_xfer(info, xfer); if (ret) { diff --git a/drivers/firmware/ti_sci.h b/drivers/firmware/ti_sci.h index 57cd04062994..dca19ca5fc49 100644 --- a/drivers/firmware/ti_sci.h +++ b/drivers/firmware/ti_sci.h @@ -910,6 +910,7 @@ struct rm_ti_sci_msg_udmap_rx_flow_opt_cfg { * 12 - Valid bit for @ref ti_sci_msg_rm_udmap_tx_ch_cfg::tx_credit_count * 13 - Valid bit for @ref ti_sci_msg_rm_udmap_tx_ch_cfg::fdepth * 14 - Valid bit for @ref ti_sci_msg_rm_udmap_tx_ch_cfg::tx_burst_size + * 15 - Valid bit for @ref ti_sci_msg_rm_udmap_tx_ch_cfg::tx_tdtype * * @nav_id: SoC device ID of Navigator Subsystem where tx channel is located * @@ -973,6 +974,11 @@ struct rm_ti_sci_msg_udmap_rx_flow_opt_cfg { * * @tx_burst_size: UDMAP transmit channel burst size configuration to be * programmed into the tx_burst_size field of the TCHAN_TCFG register. + * + * @tx_tdtype: UDMAP transmit channel teardown type configuration to be + * programmed into the tdtype field of the TCHAN_TCFG register: + * 0 - Return immediately + * 1 - Wait for completion message from remote peer */ struct ti_sci_msg_rm_udmap_tx_ch_cfg_req { struct ti_sci_msg_hdr hdr; @@ -994,6 +1000,7 @@ struct ti_sci_msg_rm_udmap_tx_ch_cfg_req { u16 fdepth; u8 tx_sched_priority; u8 tx_burst_size; + u8 tx_tdtype; } __packed; /** -- cgit v1.2.3-59-g8ed1b
