Added support for firmware download for wcn6855. Signed-off-by: Steev Klimaszewski Reviewed-by: Bjorn Andersson Tested-by: Bjorn Andersson Reviewed-by: Johan Hovold Tested-by: Johan Hovold --- Changes since v5: * Revert Set qcadev->initspeed since 6855 doesn't use it, don't touch. * Convert get_fw_build_info to a switch statement * Add poweroff handling * Fix up line alignments * Drop from microsoft extensions check since I don't actually know if we need Changes since v4: * Remove unused firmware check because we don't have mbn firmware. * Set qcadev->init_speed if it hasn't been set. Changes since v3: * drop unused regulators Changes since v2: * drop unnecessary commit info Changes since v1: * None drivers/bluetooth/btqca.c | 14 ++++++++- drivers/bluetooth/btqca.h | 10 +++++++ drivers/bluetooth/hci_qca.c | 57 ++++++++++++++++++++++++++++--------- 3 files changed, 66 insertions(+), 15 deletions(-) diff --git a/drivers/bluetooth/btqca.c b/drivers/bluetooth/btqca.c index c9064d34d830..fd0941fe8608 100644 --- a/drivers/bluetooth/btqca.c +++ b/drivers/bluetooth/btqca.c @@ -614,6 +614,9 @@ int qca_uart_setup(struct hci_dev *hdev, uint8_t baudrate, config.type = ELF_TYPE_PATCH; snprintf(config.fwname, sizeof(config.fwname), "qca/msbtfw%02x.mbn", rom_ver); + } else if (soc_type == QCA_WCN6855) { + snprintf(config.fwname, sizeof(config.fwname), + "qca/hpbtfw%02x.tlv", rom_ver); } else { snprintf(config.fwname, sizeof(config.fwname), "qca/rampatch_%08x.bin", soc_ver); @@ -648,6 +651,9 @@ int qca_uart_setup(struct hci_dev *hdev, uint8_t baudrate, else if (soc_type == QCA_WCN6750) snprintf(config.fwname, sizeof(config.fwname), "qca/msnv%02x.bin", rom_ver); + else if (soc_type == QCA_WCN6855) + snprintf(config.fwname, sizeof(config.fwname), + "qca/hpnv%02x.bin", rom_ver); else snprintf(config.fwname, sizeof(config.fwname), "qca/nvm_%08x.bin", soc_ver); @@ -685,11 +691,17 @@ int qca_uart_setup(struct hci_dev *hdev, uint8_t baudrate, return err; } - if (soc_type == QCA_WCN3991 || soc_type == QCA_WCN6750) { + switch (soc_type) { + case QCA_WCN3991: + case QCA_WCN6750: + case QCA_WCN6855: /* get fw build info */ err = qca_read_fw_build_info(hdev); if (err < 0) return err; + break; + default: + break; } bt_dev_info(hdev, "QCA setup on UART is completed"); diff --git a/drivers/bluetooth/btqca.h b/drivers/bluetooth/btqca.h index 61e9a50e66ae..b884095bcd9d 100644 --- a/drivers/bluetooth/btqca.h +++ b/drivers/bluetooth/btqca.h @@ -147,6 +147,7 @@ enum qca_btsoc_type { QCA_WCN3991, QCA_QCA6390, QCA_WCN6750, + QCA_WCN6855, }; #if IS_ENABLED(CONFIG_BT_QCA) @@ -168,6 +169,10 @@ static inline bool qca_is_wcn6750(enum qca_btsoc_type soc_type) { return soc_type == QCA_WCN6750; } +static inline bool qca_is_wcn6855(enum qca_btsoc_type soc_type) +{ + return soc_type == QCA_WCN6855; +} #else @@ -206,6 +211,11 @@ static inline bool qca_is_wcn6750(enum qca_btsoc_type soc_type) return false; } +static inline bool qca_is_wcn6855(enum qca_btsoc_type soc_type) +{ + return false; +} + static inline int qca_send_pre_shutdown_cmd(struct hci_dev *hdev) { return -EOPNOTSUPP; diff --git a/drivers/bluetooth/hci_qca.c b/drivers/bluetooth/hci_qca.c index 3df8c3606e93..38ff962662ff 100644 --- a/drivers/bluetooth/hci_qca.c +++ b/drivers/bluetooth/hci_qca.c @@ -1317,7 +1317,8 @@ static int qca_set_baudrate(struct hci_dev *hdev, uint8_t baudrate) /* Give the controller time to process the request */ if (qca_is_wcn399x(qca_soc_type(hu)) || - qca_is_wcn6750(qca_soc_type(hu))) + qca_is_wcn6750(qca_soc_type(hu)) || + qca_is_wcn6855(qca_soc_type(hu))) usleep_range(1000, 10000); else msleep(300); @@ -1394,7 +1395,8 @@ static unsigned int qca_get_speed(struct hci_uart *hu, static int qca_check_speeds(struct hci_uart *hu) { if (qca_is_wcn399x(qca_soc_type(hu)) || - qca_is_wcn6750(qca_soc_type(hu))) { + qca_is_wcn6750(qca_soc_type(hu)) || + qca_is_wcn6855(qca_soc_type(hu))) { if (!qca_get_speed(hu, QCA_INIT_SPEED) && !qca_get_speed(hu, QCA_OPER_SPEED)) return -EINVAL; @@ -1428,7 +1430,8 @@ static int qca_set_speed(struct hci_uart *hu, enum qca_speed_type speed_type) * changing the baudrate of chip and host. */ if (qca_is_wcn399x(soc_type) || - qca_is_wcn6750(soc_type)) + qca_is_wcn6750(soc_type) || + qca_is_wcn6855(soc_type)) hci_uart_set_flow_control(hu, true); if (soc_type == QCA_WCN3990) { @@ -1446,7 +1449,8 @@ static int qca_set_speed(struct hci_uart *hu, enum qca_speed_type speed_type) error: if (qca_is_wcn399x(soc_type) || - qca_is_wcn6750(soc_type)) + qca_is_wcn6750(soc_type) || + qca_is_wcn6855(soc_type)) hci_uart_set_flow_control(hu, false); if (soc_type == QCA_WCN3990) { @@ -1682,7 +1686,8 @@ static int qca_power_on(struct hci_dev *hdev) return 0; if (qca_is_wcn399x(soc_type) || - qca_is_wcn6750(soc_type)) { + qca_is_wcn6750(soc_type) || + qca_is_wcn6855(soc_type)) { ret = qca_regulator_init(hu); } else { qcadev = serdev_device_get_drvdata(hu->serdev); @@ -1723,7 +1728,8 @@ static int qca_setup(struct hci_uart *hu) bt_dev_info(hdev, "setting up %s", qca_is_wcn399x(soc_type) ?
